Effects of soil water deficit at different growth stages on rice growth and yield under upland conditions. 1. Growth during drought

Effect of temporary drought at different growth stages on snap bean pod quality and yield

“…Delayed maturity due to drought during vegetative growth may be due to low assimilation of photo-assimilate by stressed plants, which results in a slow growth rate (Boonjung and Fukai, 1996). Drought stress during V4.4 stage reduces leaf area and photoassimilation capacity (Hossain et al, 2015).…”

Rice Flag Leaf Physiology, Organ and Canopy Temperature in Response to Water Stress

“…Water is an important limiting factor for crops, adversely affecting their overall growth and development (Boonjung and Fukai, 1996;Kato et al, 2007), accumulation and revolution of dry material and photosynthetic characteristics (Kumar et al, 2006;Li et al, 2008;Wang et al, 2008), along with their yield and quality Yang et al, 2002). However, Zheng et al (2006) reported that water stress after heading had little effect on the yield of rice, and Wang et al (2004) reported that moderate water stress at the heading and filling stages significantly promoted the grain filling and increased the seed setting rate and grain weight.…”

Screening of some rice varieties and landraces cultivated in Nigeria for drought tolerance based on phenotypic traits and their association with SSR polymorphism

“…This accession is able to utilise much of the available water to grow in the absence of conservative drought responses, such as stomatal closure which restricts water use and maintains leaf water potential (as with isohydric species). Reports suggest that rice under severe drought shows anisohydric behaviour (Boonjung and Fukai, 1996;Jongdee et al, 2002;Sibounheuang et al, 2006) keeping their stomata open and photosynthetic rates high for longer periods, even in the presence of decreasing leaf water potential. Root growth was also maintained in IJS-09 and FARO-44, Groups 5 and 3 accessions respectively, where limited drought induced little reductions in leaf water potential, while the opposite was true for AGWU-116.…”
