PLANT WATER RELATIONS AND PHENOLOGICAL SHIFTS IN RESPONSE TO DROUGHT IN CASTANOPSIS INDICA AT PHULCHOWKI HILL, KATHMANDU, NEPAL

Agronomic and Photosynthetic Characteristics of Different Maize Hybrids in Response to Water Deficit Stress at Different Phenological Stages

The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...

Differences in growth and water relations among Phaseolus vulgaris cultivars in response to induced drought stress.

Relatively little ecophysiological research has been conducted to determine the responses to drought of Phaseolus vulgaris. Four bean cultivars (cvs.) from Brazil, A320, Carioca, Ouro Negro and Xodó were submitted to an imposed water deficit in order to evaluate the importance of some adaptive mechanisms of drought resistance through the analysis of growth parameters, water status, gas exchange...

Response to seasonal drought in three cultivars of Ceratonia siliqua L.: leaf growth and water relations

Alteration of Water Relations and Yield of Corn Genotypes in Response to Drought Stress

The influence of drought stress on internal water status and the final grain yield of three Egyptian corn (Zea mays L.) genotypes; GIZA2, TWC310 and TWC320 at different developmental stages was investigated. Plants grown in pots were subjected to four levels of water stress at vegetative and tassel emergence stages. Exposure of plants to drought led to noticeable decreases in leaf water potenti...

Response to seasonal drought in three cultivars of Ceratonia siliqua: leaf growth and water relations.

Responses of leaf growth and leaf water relations to seasonal drought were monitored during two successive years in three cultivars (Galhosa, Espargal and Mulata) of Ceratonia siliqua L. growing in the field in southern Portugal. Leaf water relations of fully expanded leaves were characterized by pressureâ volume analysis, and morphometric measurements of petiolar xylem were made. The three cu...
