Maize (Zea mays) is one of the important food crops of India with other potential uses in preparation of livestock feed and biofuel. But production of maize in India is low compared to top maize producing countries due to abiotic stresses (Ranum et al., 2014). Among abiotic stresses affecting maize production in India, drought is the major limiting factor. In spite of extensive research on drou...

Dry bean (Phaseolus vulgaris L.) is highly susceptible to drought stress, and drought affects 60% of global bean production. We evaluated elite exotic dry bean germplasm derived from the Mesoamerican gene pool for drought tolerance, yield, and adaptation to western Nebraska during 2006 and 2007 at three research sites. Seven tropical lines were evaluated with two great northern cultivars (Matte...

To explore the mechanisms underlying water regulation in clonal plants and its effects on carbon assimilation under water stress, we studied the responses of water status, gas exchange and abscisic acid (ABA) contents to water stress in leaves of pairs of strawberry ramets that consist of mother and daughter ramets. There was a greater decrease in photosynthetic rates (P(n)) and stomatal conduc...

Increase of frequency, duration, and intensity drought heatwave related water heat crops stress are among the principal effects climate change. This paper reports: (i) effect calcite particle film (CaPF) as a mitigation strategy against in well-watered (WW) or drought-stress (D) conditions; (ii) response leaf angle variation to stomatal conductance changes induced by Aleatico grapevine cultivar...

Agricultural industry is subjected to enormous environmental constraints, particularly due to salinity and drought. We evaluated the role of silicon (Si) in alleviating salinity and drought induced physio-hormonal changes in soybean grown in perlite. The plant growth attributes i.e., shoot length, plant fresh weight and dry weight parameters of soybean improved with elevated Si nutrition, while...

The response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. Common bean (Phaseolus vulgaris L.) is the most important pulse crop that is cultivated worldwide for human consumption. Understanding of the mechanisms responsible for its response to drought is, therefore, essential. An increasing numbe...

In this study, two-year-old bare-root Acer negundo and pseudoplatanus seedlings were grown indoors (control vs. drought-stressed) outside the hoop house to examine leaf gas exchange parameters in late growing period. Besides morphological features, several parameters, such as net photosynthetic rate (Anet), transpiration (E), stomatal conductance (gs), intercellular CO2 ambient (Ci/Ca), water u...

The effect of drought on the photosynthetic apparatus of leaves of Salix sp. was studied by measurements of the induction of chlorophyll fluorescence and the capacity for O(2) evolution. Using a multivariate analysis, a model was developed that could predict the degree of drought stress from the data of fluorescence kinetics. Even mild drought stress was detected with high precision; this was n...

The dynamics of local climates make development of agricultural strategies challenging. Yield improvement has progressed slowly, especially in drought-prone regions where annual crop production suffers from episodic aridity. Underlying drought responses are circadian and diel control of gene expression that regulate daily variations in metabolic and physiological pathways. To identify transcrip...

Dissection of the genetic loci controlling drought tolerance traits with a complex inheritance is important for drought-tolerant sugarcane improvement. In this study, we conducted large-scale candidate gene association study 649 genes in diversity panel to identify variants underlying agronomic and indices evaluated plant cane ratoon under water-stressed (WS) non-stressed (NS) environments. We ...
