The above inclusions show that the plant water stress is due to the lack of water, Thereis obvious negative correlation between CWSI and leaf water potential.
The tissue water content, water potential and, soluble sugar, as well as SOD and CAT activity of those samples were determined, respectively.
The analysis of variance shows a significant effect on the interaction of heat stress and growing media on leaf water potential when the treatment is applied only at midday.
Leaf water potential and transpiration velocity of plant is two important physiologic index that reflect water regime of plant.
Based on the theoretical analyses of water potential, a mathematical model of low-temperature vacuum drying was developed.
The model can predict not only the soil water dynamic profiles and the soil water potential profiles, but the changes of the effective root density with depth and time.
The diurnal change of water potential and water content of roots at dry side opposed to the transpiration.
It was revealed that significant differences in leaf water potential, stomatal resistance, transpiration rate, and rate of water loss of excised-leaves existed among genotypes.
During the day water loss by transpiration exceeds water absorption by the roots and leaf water potential decline.
The main characteristics of drought tolerance in plants which are of the ability of dehydration tolerance with low water potential are maintenance of turgor and protoplasmic desiccation tolerance.
Root water potential and root growth potential had strongly correlated, and should be considered as the main indicators for physiological and vigor.
Blade Angle is strikingly correlated to xylem water potential at midday.
Data from experiments carried out in peach field were analyzed and the patterns of soil water potential variation described.
Water deficit is influenced by the level of soil water potential at the root surface.
The change of root water potential is reverse.
