Abstract:
... Citrus Black Spot (CBS), caused by the ascomycete, Phyllosticta citricarpa, is a fruit, foliar, and twig spotting fungal disease affecting the majority of commercial cultivars of citrus. The disease causes cosmetic lesions, may cause fruit drop and P. citricarpa is considered a quarantine pathogen by some countries, impacting domestic and international trade of citrus fruit. Regulatory requirement ...

Abstract:
... Photoperiodic lighting can promote flowering of long‐day plants (LDPs) and inhibit flowering of short‐day plants (SDPs). Red (R) and far‐red (FR) light regulate flowering through phytochromes, whereas blue light does so primarily through cryptochromes. In contrast, the role of green light in photoperiodic regulation of flowering has been inconsistent in previous studies. We grew four LDP species ( ...

Abstract:
... BACKGROUND: Appropriate plant architecture can improve the amount of cotton boll opening and allow increased planting density, thus increasing the level of cotton mechanical harvesting and cotton yields. The internodes of cotton fruiting branches are an important part of cotton plant architecture. Thus, studying the molecular mechanism of internode elongation in cotton fruiting branches is highly ...

Here, we present a comparative microbiome analysis of endosymbiotic bacteria spanning the entire phylogenetic tree. We ...

Abstract:
... In cotton, the formation of fruiting branches affects both plant architecture and fiber yield. Here, we report map-based cloning of the axillary flowering mutation gene (GbAF) that causes bolls to be borne directly on the main plant stem in Gossypium barbadense, and of the clustered boll mutation gene (cl₁) in G. hirsutum. Both mutant alleles were found to represent point mutations at the Cl₁ locu ...

Abstract:
... BACKGROUND: and Aims Soil water deficit is a major abiotic stress with severe consequences for the development, productivity and quality of crops. However, it is considered a positive factor in grapevine management (Vitis vinifera), as it has been shown to increase grape quality. The effects of soil water deficit on organogenesis, morphogenesis and gas exchange in the shoot were investigated. METH ...

Abstract:
... A field experiment was conducted in 2000, 2001, and 2002 at Stoneville, MS, to determine the effect of spurred anoda interference on yield loss of two cotton cultivars, ‘‘Delta Pine 5415’’ and ‘‘Pima S-6’’, grown under wide (1 m) (WR) and ultra narrow (0.25 m) row (UNR) spacings. The relationship between spurred anoda density and dry weight per plot was linear each year. At a spurred anoda density ...

Abstract:
... The present study addresses the prediction of apple tree development, taking into account both the number and within-tree position of tree components. The architectural development of two trees per scion cultivar, 'Fuji' and 'Braeburn', was studied by describing all shoots over 6 years. Flowering and fruiting were observed over 3 years. The description included different scales [entire trees, axes ...

Abstract:
... The ability of peanut plants to adjust to wide plant-to-plant spacing and the use of more precise mechanical planters have not been thoroughly exploited to reduce seeding rates. The magnitude of plant growth adjustment of two runner peanut cultivars to reduced seeding rate was studied in 1992 and 1993. A precision vacuum planter was used to plant the cultivars GK-7 and Southern Runner (SR) in sing ...

Abstract:
... A better understanding of how drought stress affects soybean [Glycine max (L.) Merr.] seed-yield determination would aid in the development of improved cultivars for the southeastern Coastal Plain and better production systems aimed at ameliorating the effects of drought stress. The objective of this field study was to examine the effects of drought stress on both soybean branch vegetative growth ...

Abstract:
... The growth characteristics of six and the reproductive development of five soybean [Glycine max (L.) Merr.] cultivars were examined at 39 Pa (ambient) and 70 Pa (elevated) CO2 partial pressures in temperature-controlled glasshouses. Significant intraspecific variation for both growth and seed yield in response to elevated CO2 was observed among the cultivars. At elevated CO2, total biomass increas ...

Abstract:
... Oviposition and larval development of pink boll worm (PBW), Pectinophora Gossypiella (Saunders), on a breeding stock of upland cotton, Gossypium hirsutum L., designated AET-5, was compared to that on a commercial cultivar, 'Deltapine 61' (DPL-61), in greenhouse no-choice and free-choice tests, and in field free-choice tests. The field resistance of AET-5 was caused mainly by lower PBW oviposition. ...
