Low leaf hydraulic conductance associated with drought tolerance in soybean.
Lack of water is the most serious environmental constraint on agricultural production. More efficient use of water resources is a key solution for increased plant productivity in water-deficit environments. We examined the hydraulic characteristics of a 'slow wilting' phenotype in soybean (Glycine max Merr.), PI 416937, which has been shown to have relatively constant transpiration rates above ...
متن کاملLeaf rolling reduces photosynthetic loss in maize under severe drought
Effects of leaf rolling (LR) on maize photosynthesis under severe drought stress were studied in two cultivars with opposite drought responses, Batem 56-55 (drought tolerant) and Batem 51-52 (drought sensitive). Drought stress and artifi cial prevention of leaf rolling (PLR) were applied at grain fi lling stage for 30 days. LR in Batem 56-55 occurred later than in Batem 51-52. Leaf water potent...
متن کاملNew insight into leaf drought tolerance
Drought-induced forest dieback appears to have increased in frequency over the last decade (Van Mantgem et al. 2009; Allen et al. 2010; Peng et al. 2011). These diebacks have occurred across a wide diversity of forest types, suggesting that no forest biome is invulnerable to climate change (Choat et al. 2012). However, drought-influenced mortality rates differ substantially between species grow...
متن کاملLeaf water potential, stomatal resistance, and photosynthetic response to water stress in peach seedlings.
Individual groups of peach (Prunus persica [L.] Batsch) seedlings stressed to -17, -26 and -36 bars recovered to control levels within 1, 3, and 4 days, respectively. Stomatal resistance was significantly correlated with both leaf water potential and net photosynthesis. In seedlings stressed to -52 bars, leaf water potential and stomatal resistance recovered sooner than net photosynthesis, desp...
متن کاملEvaluation of Drought Tolerance in Rapeseed (Brassica napus L.) Cultivars Using Drought Tolerance Indices
Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...
