Leaf water potential leaf), typically measured using the pressure chamber, is the most important metric of plant water status, providing high theoretical value and information content for multiple ...
In this study we investigated the needle water potential of different pine species using a pressure chamber during winter months. Totally, seven pine species Pinus jeffreyi Greville & Balfour, Pinus p...
Irrigation efficiency improvement requires optimization of its parameters like irrigation scheduling, threshold and amount of water usage. If these parameters are not satisfactorily optimized, negat...
‘Meiwa’ kumquat (Fortunella crassifolia Swingle) trees were subjected to water stress in order to increase first-flush flowers by withholding water until the soil water content reached about 30% and w...
In order to clarify the dominant factor responsible for the reduction in photosynthetic rate caused by 1) an increase in leaf-air vapor pressure difference and 2) a decrease in leaf water potential i...
Rice panicles start to transpire just after heading. We can therefore expect that the water potential of panicles changes little prior to heading and varies in response to transpiration after heading...
It has been observed that wheat has a shallow root system in wet soil and a deep root system in dry soil. However, the control mechanisms of root growth depending on soil water status remain unclear. ...
In the previous report, we indicated that cold wind injury of tea leaf in Sanin region occurred under decreases of leaf water potential (ΨL) caused by low temperature and strong wind. We attempted to ...
Tea leaf sometimes receives serious damage as leaf blight or defoliation by winter cold wind in Sanin region of Japan. When wind of 4-7ms-1 blew, air temperature decreased to 0∼-4.4°C and a litt...
Experiments were conducted to examine whether the responses in panicle water potential under drought changes with panicle development. Twenty seedlings of two rice cultivars, Norin 20 and Milyang 23, ...
We observed previously (Part 1) that maintenance ability of leaf water potential (Ψ1) in rice plants under paddy field conditions changed depending on planting years and seasons and individual locatio...
Because the leaf water potential (Ψ1) of the rice plant (Oryza sativa L.) is strongly affected by the evaporative demand of the atmosphere under paddy field conditions, and most changes in Ψ1 reflect ...
This research was conducted to elucidate the mechanisms in water stress tolerance of Oryza glaberrima Steud. with special reference to stomatal conductance. Leaf photosynthesis (LPS) of O. glaberrima...
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...
Even though the nitrogen content (mgNdm-2) of rice leaves is the same, a large difference in the net photosynthetic rate (Pn) has been recognized. To determine the reasons for the difference, leaf xyl...
