Abstract:
... Growth rates vary widely among plants with different strategies. For crops, evolution under predictable and high‐resource environments might favour rapid resource acquisition and growth, but whether this strategy has consistently evolved during domestication and improvement remains unclear. Here we report a comprehensive study of the evolution of growth rates based on comparisons among wild, landr ...

Abstract:
... Methyl jasmonate (MeJA) is an airborne hormonal elicitor that induces a fast rise of emissions of characteristic stress marker compounds methanol and green leaf volatiles (GLV), and a longer-term release of volatile terpenoids, but there is limited information of how terpene emissions respond to MeJA in terpene-storing species. East-Indian lemongrass (Cymbopogon flexuosus), an aromatic herb with a ...

Abstract:
... The crop of broccoli in tropical regions is of great importance among flowering vegetables; however, the yield of this crop is severely impacted by climatic variations that can cause floods. In Tunja, Colombia, a study was carried out under greenhouse conditions in which the tolerance of broccoli plants to prolonged waterlogging was evaluated. One group of plants were kept under waterlogging condi ...

Abstract:
... Water use efficiency (WUE) and total transpiration (T) are the two pivotal traits that determine the differences in total biomass (BM) accumulation. A significant genetic variability in these traits has been demonstrated in several crop species. Exploring of latter traits through breeding efforts to improve crop productivity have been rather slow in rice. To achieve success in crop improvement, it ...

Abstract:
... Plants develop mechanisms that confer tolerance to sun or shade exposure and the knowledge of their responses may help to devise strategies for the conservation of natural populations and their propagation. We study the effect of shading on the ecophysiology and anatomy of Epiphyllum phyllanthus to determine its plasticity and tolerance. Specimens of E. phyllanthus were subjected to full sun, 35%, ...

Abstract:
... Salinity makes disorder to plant physiological causes decreasing in biomass production. Applying silica nutrients is expected to increase paddy (Oryza sativa L.) tolerance to salinity. The study aims to examine the effects of the application of silica nutrients under saline conditions regarding plant growth analysis and its correlation to paddy biomass production. The research was arranged in a fa ...

Abstract:
... Agriculture must improve the productivity of irrigation water due to several factors, such as global warming, the increasing water demand of other sectors or the protection of the environment. The “optimized regulated deficit irrigation for limited volumes of water” (ORDIL) methodology may contribute to reach this objective by optimizing the allocation of irrigation water during the growing cycle, ...
... Heat stress is one of the most important abiotic stresses confronted by plants under global climate change. Plant exposure to abiotic or biotic stress can improve its tolerance to subsequent severe episodes of the same or different stress (stress priming), but so far there is limited comparative information about how pre-exposures to different abiotic and biotic elicitors alter plant resistance to ...

Abstract:
... A field experiment was conducted during the winter (rabi) season of 2017–18 and 2018–19 at Chandra Shekhar Azad University of Agriculture and Technology Kanpur, Uttar Pradesh, to study the influence of irrigation scheduling and weed-management practices on growth and productivity of wheat (Triticum aestivum L.). The experiment was laid out in split-plot design with 4 irrigation scheduling in main ...
... In recent decades, nano-scale zero valent iron is reported to have plant growth enhancement capacity under laboratory conditions, but till date, there is no report to highlight its effect on the growth and yield of field-grown plants. In this study, we have evaluated the potential of nZVI priming on rice yield. A two-year field study has been conducted with different concentrations (10, 20, 40, an ...
... Sodium (Na) and arsenic (As) toxicity were monitored by hyperaccumulation of metals in Salvinia natans L. with 2,4-dichlorophenoxyacetic acid (2,4-D) induction. Salvinia was recorded with significant bioaccumulation of those metals with de-folding of cellular attributes in sustenance under toxic environment. 2,4-D priming has revised the growth components like net assimilation rate and relative wa ...

Abstract:
... Irrational use of agro chemicals decreases the ecological diversity and increases the biotic and abiotic stresses, ultimately affects the crop yield. The use of active silica counters such ill effects and also enhances the crop yield especially under organic farming. Therefore, a field experiment was conducted during the Kharif season of 2018 and 2019 at Organic Unit of Instructional Farm, Rajasth ...

Abstract:
... Establishing rice (Oryza sativa L.) crops by direct-seeding requires less water and less labor than transplanting. However, farmers need to know the net effects of suites of practices. So, evaluations of direct-seeding should also consider its interactions with other factors, including a practice, such as seed-priming. This paper reports on an experiment conducted in 2014 and 2015 at University of ...

Abstract:
... The effect of two drought acclimation treatments—high (HS) or moderated (MS) drought stress—on seedling growth was assessed in the two tree species Caesalpinia platyloba S.Watson (Fabaceae) and Ipomoea wolcottiana Rose (Convolvulaceae) in order to prepare them for dry spells. These species are mainly distributed in mature and disturbed sites, respectively, in a seasonal tropical dry forest in Jali ...

Abstract:
... Due to relatively low yield as well as low resources use efficiency with double rice (Oryza sativa L.) cropping systems (RR), exploring new cropping systems to increase yield and resources use efficiency simultaneously has become a large challenge of the middle reaches of the Yangtze River (MRYR). Our previous study demonstrated that the maize (Zea mays L.)–rice cropping system (MR) exhibited high ...

Abstract:
... Recent studies indicate that warming impairs the physiological performance of several plants; however, the warming effect depends on the thermal tolerance of each plant species. The effects of warming on oat ecophysiology and its biomass production have been little studied, although world oat demand is rising. Our aim was to evaluate how induced warming affects the ecophysiology and biomass produc ...
