| 摘 要： | 通过对盆栽桃树果实贮存水运转动态的数学模拟发现，果实的贮存水汇入蒸腾流的最大量只占全天茎流总量的1．4％左右。白天，贮存水从果实汇入蒸腾流；晚上，由树干流入果实。晴天贮存水的变化明显大于阴天，其变化规律与水势的变化相一致，而水势的变化又主要是由太阳辐射的变化引起的。

THE DYNAMIC VARIETY OF STORAGE WATER IN PEACH FRUIT |
| |
| Abstract: | Through the simulation of the dynamic variety of storage water in peach fruit, we found that the storage water, which flow in transpiration stream was only 1.4% in total sap flow of a day. The fruit storage water is flow in transpiration steam in the day, but flow in fruit in night. And the variety in clear days is bigger than that of overcast day, but the pattern is similar to that of that of overcast days. And the variety is depend on the variety of water potential which depends on solar radiation. |
