Abstract:
... The geometrical structure of plant canopies has many implications for plant functioning, microclimatic conditions, and plant‐pathogen/herbivore interactions. Plant geometry can be described at several scales. At the finest scale, canopy structure includes the shape, size, location, and orientation of each organ in the canopy. This data set reports the three‐dimensional (3‐D) geometry of a set of f ...
... There are multiple flow paths with different flow directions in fracture intersections. A general flow model synthetically describing the nonlinear flow behavior of multiple flow paths in different directions in two-dimensional fracture intersections was proposed for the analysis of fluid flow in rock fracture networks. The flow behavior of seven typical fracture intersection models, according to ...

Abstract:
... How much ABA can be supplied by the roots is a key issue for modelling the ABA-mediated influence of drought on shoot physiology. We quantified accumulation rates of ABA (SABA) in maize roots that were detached from well-watered plants and dehydrated to various extents by air-drying. SABA was estimated from changes in ABA content in root segments incubated at constant relative water content (RWC). ...
... Instance segmentation for high-resolution remote sensing images (HRSIs) is a fundamental yet challenging task in earth observation, which aims at achieving instance-level location and pixel-level classification for instances of interest on the earth’s surface. The main difficulties come from the huge scale variation, arbitrary instance shapes, and numerous densely packed small objects in HRSIs. In ...
... Ecotype formation in eight populations of Echium leucophaeum was studied on La Palma (Canary Islands) at 100—m intervals from sea level to 600 m elevation. Climate varied with altitude, the lower elevation having higher temperatures, evaporation, and wind velocity and lower rainfall. A method for recording growth form of individual plants was developed whereby lateral branch production and branchi ...
branches; branching; clones; dieback; plant propagation; population density; simulation models
Abstract:
... Many plants reproduce clonally through vegetative extensions (spacers). This results in a patch of clones connected through a network of spacers. The resulting network has a nontrivial spatial pattern that can be an important determinant of survival and fitness of the clonal plant. Here, we develop general growth rules that dictate how individual clones under local density-dependent conditions add ...
... Fractal branching models can provide a non-destructive and generic tool for estimating tree shoot and root length and biomass, but field validation is rarely described in the literature. We compared estimates of above ground tree biomass for four indigenous tree used on farm in the Philippines based on the WanFBA model tree architecture with data from destructive sampling. Allometric equations for ...
... Plant density and sowing date were shown to affect branching in spring-sown white lupin (Lupinus albus L.), but the response varied among environments. The patterns of primary and secondary branching in the cv. Lublanc were studied as a function of both the number of axillary buds and the plant growth rate. Field experiments that used a wide range of sowing dates and plant densities to alter plant ...
... Since the first report of the 'A72' semidwarf peach [Prunus persica (L.) Batsch] tree in 1975, no new information has become available on this genotype. We evaluated the growth habit and verified the inheritance of 'A72' in a population of 220 progeny derived from self-pollination. Detailed tree and branch measurements revealed a unique forked-branch (FBR) character of the 'A72' (Nn) phenotype. Th ...
... Control of branch development is a major determinant of architecture in plants. Branching in petunia (Petunia hybrida) is controlled by the DECREASED APICAL DOMINANCE (DAD) genes. Gene functions were investigated by plant grafting, morphology studies, double-mutant characterization, and gene expression analysis. Both dad1-1 and dad3 increased branching mutants can be reverted to a near-wild-type p ...

Abstract:
... Plant architecture highly constrains pest infestation but is rarely considered in studies on plant–insect interactions. We analysed the relationships between apple tree architectural traits manipulated by tree training and within-branch development of Dysaphis plantaginea (rosy apple aphid, RAA), a major apple pest, during its multiplication wingless phase in spring. We hypothesised that the degre ...
... Apical control is the inhibition of a lateral branch growth by shoots above it (distal shoots). If the distal shoots are cut off to remove apical control, the lateral branch can grow larger and may bend upwards. Apical control starts when new lateral buds grow after passing through a period of dormancy. Buds initially break and produce leaves, then apical control is exerted and the lower (proximal ...
... In 1999-2001, at the Lithuanian Institute of Horticulture, the effects of apple rootstocks M.26Vf, M.26, MM.106Vf, MM.106, B.118, B.396, P 60, P 22 and Antonovka seedlings on the quality of one-year-old planting material were studied. Ten apple cultivars were included in the trial. The influence of rootstock on tree height, stem diameter, lateral branching and spur formation and branch length was ...
... • In the apple tree (Malus domestica), shoot architecture – the distribution of lateral bud types and growth along the parent shoot – has been extensively investigated. The distal zone of a shoot is characterized by a high proportion of vegetative or floral axillary branches mixed with latent buds and aborted laterals. The hypothesis tested here was that bud development was related to hydraulic co ...

Abstract:
... Epicormic branches can be a serious silvicultural problem in many Quercus species because of the potential reduction in log value associated with their occurrence. The phenomenon is also problematic for tree improvement since the genetic component of epicormic branching has not been well quantified. The strong influence of ontogeny on epicormic development in Quercus is well established; however, ...
... BACKGROUND AND AIMS: Intra-specific variation in root system architecture and consequent efficiency of resource capture by major crops has received recent attention.

METHODS: A subset of 111 genotypes ...
... Large wood (LW) exerts an important influence on the geomorphology and ecology of streams and rivers. The magnitudes of flow forces on LW are needed to support stream management activities and are typically computed using time mean lift and drag coefficients determined in laboratory flumes using small, smooth cylinders. Herein we report measurements of forces on LW of varying complexity (simple cy ...
... Nonstructural carbohydrate concentrations in stems are greater for sweet than grain sorghums [Sorghum bicolor (L.) Moench). Knowledge of plant characteristics associated with high nonstructural carbohydrates in sweet sorghum will aid efforts to increase nonstructural carbohydrates in grain sorghum stems. This study tested the hypothesis that variation of CO₂ assimilation rate, leaf area, branching ...
... Mutations within the Arabidopsis METHYL-CpG BINDING DOMAIN 9 gene (AtMBD9) cause pleotropic phenotypes including early flowering and multiple lateral branches. Early flowering was previously attributed to the repression of flowering locus C (FLC) due to a reduction in histone acetylation. However, the reasons for other phenotypic variations remained obscure. Recent studies suggest an important fun ...
... The functional characterization of mammalian proteins containing a methyl-CpG-binding domain (MBD) has revealed that MBD proteins can decipher the epigenetic information encoded by DNA methylation, and integrate DNA methylation, modification of chromatin structure and repression of gene expression. The Arabidopsis genome has 13 putative genes encoding MBD proteins, and no specific biological funct ...
... Cultural practices for canopy management in grapevines rely on intensive manipulation of shoot architecture to maintain canopy light levels. In contrast to common model plant systems used to study regulation of branch outgrowth, the grapevine has a more complex architecture. The node contains first, second and third order axillary meristems. The prompt bud (N+1) develops into a summer lateral and ...

Abstract:
... To investigate crown development patterns, branch architecture, branch-level light interception, and leaf and branch dynamics were studied in saplings of a plagiotropically branching tree species, Polyalthia jenkinsii Hk. f. & Thoms. (Annonaceae) in a Malaysian rain forest. Lengths of branches and parts of the branches lacking leaves ('bare' branches) were smaller in upper branches than in lower b ...
... Although the basal and uppermost lateral branches of Lupinus angustifolius L. frequently grow and contribute to yield, buds formed in the axils of leaves 6-12 (referred to as middle buds) rarely grow. This may be due to an inherent limitation of these buds, or some form of apical dominance or competition imposed by the plant. The hypothesis that middle buds have the full capacity to grow, but rema ...
... The concentrations of indole-3-acetic acid (IAA), cytokinins (CK) and abscisic acid (ABA) were measured in buds of different regions (main stem and lateral branches) of Lupinus angustifolius L. (cv. Merrit) and at different stages in the development of branches. In lupin, branching patterns are the result of discrete regions of axillary branches (upper, middle and basal) which elongate at much dif ...
... Custard apple has cryptic axillary buds, hidden from view by the base of the petiole. This has led to confusion about custard apple's flowering habit. Flowering only occurs during early branch development, and can be forced at any time of the growing season simply by removing leaves. Here, we show that flowering is terminal, not extra-axillary, and that the apparent continuation of the main stem b ...

... Plant architecture governs living conditions of herbivores. In fruit trees, the perennial structure is modulated by training and pruning which may affect pests. The effect of tree architecture manipulation on the development of the rosy apple aphid Dysaphis plantaginea (RAA) was investigated from 2002 to 2009 in apple orchards. The first step (2002-2005) consisted in comparing the Centrifugal Trai ...
... Attachment of branches in Schefflera is unusual in that it involves fingerlike woody extensions that originate in the cortex and pass gradually into the woody cylinder of the parent shoot. We tested the hypothesis that these structures could be roots since Schefflera is a hemi-epiphyte with aerial roots. These branch traces originate by secondary development in the many leaf traces (LTs) of the mu ...
... Developmental self-assembly of DNA nanostructures provides an ideal platform for studying the power and programmability of kinetically controlled structural growth in engineered molecular systems. Triggered initiation and designated sequencing of assembly and disassembly steps have been demonstrated in structures with branches and loops. Here we introduce a new strategy for selectively activating ...
... The developmental morphology of Terniopsis malayana, an unusual aquatic angiosperm from Thailand, was examined. A unique vegetative structure called the “ramulus” arises endogenously in the root tissue. The ramulus has an actively growing apical meristem. The ramulus branches several times to form a “ramulus complex” consisting of up to six ramuli, which are distichously arranged in almost a singl ...
... An increase in temperature and water deficits caused by the ongoing climate change might lead to a decline growth rates and threaten the persistence of tree species in drought-prone areas within the Mediterranean Basin. Developmental instability (the error in development caused by stress) may provide an index of the adaptability of woody plants to withstand climatic stressors such as water shortag ...
... • Premise of the study: Podostemaceae is a unique family of aquatic angiosperms that grow in swift-running water on rock surfaces in the tropics. Their plant bodies show a remarkable adaptation: the main plant body is mostly creeping or flattened, or in extreme cases foliose, functioning as an adhering and photosynthetic organ. In the subfamily Podostemoideae, the root is foliose, whereas in the s ...
... Branching is a key factor in the evolutionary diversification of plants and is a main criterion for plant architecture analysis. Among descriptive features, acrotony is defined as increased vigor of the vegetative proleptic branches (from dormant buds), from the proximal to the distal part of the parent growth unit. I hypothesized that acrotony could be extended to other, usually poorly described, ...
... Very little is known about how growth is distributed within thalli of fruticose lichens. To determine whether mature, non-apical regions of the beard lichen Ramalina usnea elongate, segments of the broadest axes were marked with thread and measured; thalli were then returned to the field to resume growth for about one year. Growth was evident in all segments measured and increments were roughly pr ...
... Jatropha shrubs grow tall if left non-pruned. Pruning helps to keep the height within harvestable distances. Since, Jatropha flowers are borne on leaf axils of new growth in the season, pruning is supposed to increase fruiting because of formation of more number of lateral branches due to suppression of apical dominance. However, results of exploratory studies revealed drastic reduction of fruit y ...
... In this study, in situ catalytically generated allylic indium from 1,3 dienes and InCl₂H was developed for use in the allylation of ketones. This protocol resulted in the unprecedented establishment of a successive combining of quaternary C–C bonds, which could then be applied to many types of ketones. Other branched 1,3 dienes and vinyl cyclopropanes, could also be coupled with ketones in a react ...

Abstract:
... In the paper, there is analysed one particular approach to the modelling uncertainty in the project management through an original version of the fuzzy CPM (Critical Path Method). First there is shown the relevance of using the fuzzy CPM in agriculture and the related branches and present the basics of the methods used. Then, there are described the imperfections of the work which is discussed and ...
... With the discovery of strigolactones as root exudate signals that trigger parasitic weed seed germination, and then as a branching inhibitor and plant hormone, the next phase of strigolactone research has quickly revealed this hormone class as a major player in optimizing plant growth and development. From the early stages of plant evolution, it seems that strigolactones were involved in enabling ...
... Branching is a key determinant of architectural quality of ornamental plants. Using plants trained to a single primary shoot, cultivars of Japanese maple (Acer sp.) 'Fireglow', 'Katsura', 'Orangeola', 'Red Emperor', 'Skeeter's Broom' and 'Sango Kaku' presented a diverse range of growth and sylleptic branching patterns. Shoot extension was more vigorous in 'Sango Kaku', which displayed uninterrupte ...
... Clonal architecture is involved in performance of clonal fragments, as it determines spatial distribution of ramets. It is expected to rely on the species-specific expression of several architectural traits (structural blue-print). However, in contrasting environments, realized clonal architectures may differ, due to phenotypic plasticity. In this paper, we compared clonal architectures between tw ...
... Few studies have assessed directly the impact of warming on plant growth and biomass production in the High Arctic. Here, we aimed to investigate the impact of 7 years of warming (open greenhouses) on the aboveground relative growth rate (RGR) of Cassiope tetragona and Salix arctica in North-Eastern Greenland. RGR was assessed for apical (leaves, stem, reproductive organs) and lateral meristems (s ...

Abstract:
... Branch architecture in apple (Malus à domestica Borkh.) is defined according to the location, type (vegetative or reproductive), and length of lateral shoots. This is related to both an inherent genetic basis for architecture and the response of the lateral buds and shoots to environmental constraints. Architecture is typically viewed as the result of time and position bud burst and outgrowth, or ...
... • The performance of the whole plant is largely dependent on its ability to allocate limited resources to branches that perform best throughout its life. Here, the hypothesis that the fate of young branches is determined by their growth rates and not merely by their relative physical sizes or net photosynthetic outputs was tested. • The development of asymmetrical two‐branch plants was followed af ...
