Estimation of crop water stress index in almond orchards using thermal aerial imagery
canopy vapor pressure deficit almond
2015/1/12
An important method for estimating Crop Water Stress Index (CWSI) is by measuring surface temperature of the canopy. A remote sensing method was used to estimate CWSI of an almond orchard in Paramount...
Effect of water stress at different periods on seed yield and water use efficiency of guar under Shambat conditions
Guar Water Stress Water Use Efficiency Harvest Index
2013/3/4
Water stress effects on seed yield and water use efficiency of three indeterminate guar (Cyamopsis tetragonoloba L. Taub.) lines (L12, L18 and L33) were investigated in the experimental farm of the Fa...
Effects of Top Dressing on Growth and Panicle Dry Weight as Affected by Soil Water Stress at the Early Panicle-Development Stage in Rice (Oryza sativa L.)
Leaf area duration Net assimilation rate Rice SPAD Total dry weight
2010/3/4
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...

Interaction of Nitrogen Supply and Soil Water Stress on Photosynthesis and Transpiration in Rice
Nitrogen supply Oryza sativa L Photosynthesis Rice Stomata Water stress Water use efficiency
2009/8/6
The purpose of this study is to determine if there is an interaction of nitrogen nutrition and water stress on apparent photosynthesis (APS), transpiration (Tr), and water-use efficiency in rice (Oryz...
Changes of Heading Time and Panicle Weight in Rice Subjected to Water Stress during the Early Stage of Panicle Development
Cumulative water stress Heading time Leaf water potential Panicle weight Rice
2009/8/6
The increase of heading time in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) was demonstrated in a wetland rice cultivar Koshihikari subjec...
Growth Response of Rice (Oryza sativa L.) to Drought:II. Varietal difference in transpiration under water stress and its related plant characteristics
Drought tolerance Humidity Leaf-water content Rice Sugar content Transpiration Varietal
2009/8/5
Transpiration of a rice plant under a low water potential of rooting medium and low air-humidity conditions was studied in order to evaluate varietal difference in response to water stress. Water stre...
Growth and Adaptation of Soybean Cultivars under Water Stress Conditions:I. Leaf movement and leaf temperature
Irrigation Leaf temperature Paraheliotropic leaf movement Soybean Water stress
2009/8/4
The leaf movement of soybean under water stress conditions was investigated in terms of canopy structure and leaf temperature. Irrigated and non-irrigated treatment were conducted in concrete plots in...
Relationship between Panicle Weight per Plant and Cumulative Water Stress in Rice
Cumulative water stress Heading and anthesis Leaf water potential Panicle weight per plant
2009/7/31
Decrease of panicle weight per plant in rice in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) has been demonstrated in rice subjected to inc...
Growth and Adaptation of Soybean Cultivars under Water Stress Conditions:II. Effects of leaf movement on radiation interception
Drought resistance Integrated solarimeter film Irrigation treatment Leaf movement
2009/7/31
Leaf movement of field-grown soybeans under water stress conditions was examined with radiation interception. Two cultivars with different leaf movement, Zhenzhuta 2 (active) and Heinong 33 (inactive...
Effects of Panicle Water Potential on Water Stress Susceptibility in Rice
Development Panicle Rice Water potential Water stress susceptibility Winnowed paddy number
2009/7/30
The effects of drought on the rice yield differ depending on the time when plants are subjected to the drought. It is therefore probable that water stress susceptibility, the degree of yield reduction...
