| Abstract: | Leaf water status of Actinidia and its relationship with enviromental factors were studied under field conditions.The results showed that Leaf water potential followed a pronounced diurnal cycle from predawm maximum to midday minimun and back to the maximam from evening to the predawn.Leaf water potential before sunrise was a reliable indicator of soil water status whereas the minimun leaf water potential was influenced greatly by climatic factors.The values and ranges of the minimum leaf pofential under the same conditions reflected drought tolerance in Actinidia to some extent. |
