Effects of Deficit-irrigation at Different Stages on Evapotranspiration and Yield of Summer Maize
Guan'gai paishui xuebao, 2022 【Objective】 Deficit irrigation is a technology used widely in most arid and semi-arid regions to increase water use efficiency, but how to optimize the timing of and duration of the deficit remains elusive. The objective of this paper is to fill this gap

Evaluation of growth, yield and physiological responses of some watermelon accessions to water deficit stress [PDF]
Zīst/shināsī-i Giyāhī-i Īrān, 2018 In order to evaluate the tolerance of watermelon (Citrullus lanatus L.) accessions to water deficit stress, an experiment was carried out in a split plot based on randomized complete block design with three replicates in research filed of university of ...

Water deficits and hydraulic limits to leaf water supply [PDF]
Plant, Cell & Environment, 2002 AbstractMany aspects of plant water use – particularly in response to soil drought – may have as their basis the alteration of hydraulic conductance from soil to canopy. The regulation of plant water potential (Ψ) by stomatal control and leaf area adjustment may be necessary to maximize water uptake on the one hand, while avoiding loss of hydraulic ...

Water Deficits and Reproduction in Maize [PDF]
Plant Physiology, 1989 Reproductive development in maize (Zea mays L.) is vulnerable to plant water deficits during anthesis but becomes less sensitive as reproduction progresses. To determine whether changes in tissue water status correlated with the change in sensitivity, we examined the water potential (Psi(w)), osmotic potential (Psi(s)), and turgor of reproductive ...

Daily variations of water use with vapor pressure deficit in a plantation of I214 poplars. [PDF]
, 2009 Daily rates of whole tree water use were measured in a homogeneous 7-year-old plantation over 84 days. Two trees were selected in the two most contrasting ends, i.e., with mean water table at -1.5 m and -3.5 m. Results showed that the mean tree water use

Evaluation of corn lines and hybrids resulting from their crossing based on biochemical and physiological traits in conditions of limited irrigation stress [PDF]
بیوتکنولوژی و بیوشیمی غلات, 2022 Introduction:Water deficit stress is one of the most common environmental stresses which has limited agricultural production. So, research on the water deficit tolerance in crops is very important.Materials and methods: In this study, 15 corn genotypes ...

Molecular Responses to Water Deficit [PDF]
Plant Physiology, 1993 Water deficit elicits a complex of responses beginning with stress perception, which initiates a signal transduction pathway(s) and is manifested in changes at the cellular, physiological, and developmental levels. The set of responses observed depends upon severity and duration of the stress, plant genotype, developmental stage, and environmental ...

Water uptake by roots: effects of water deficit [PDF]
Journal of Experimental Botany, 2000 The variable hydraulic conductivity of roots (Lp(r)) is explained in terms of a composite transport model. It is shown how the complex, composite anatomical structure of roots results in a composite transport of both water and solutes. In the model, the parallel apoplastic and cell-to-cell (symplastic and transcellular) pathways play an important role ...
