摘要
通过对无性繁殖的 9个种源进行春笋不同部位含水率和新竹枝叶含水率动态的测定 ,结果表明 :种源间含水率没有显著差异 ,但春笋不同部位和新竹枝叶不同月份含水率有显著差异 ;春笋含水率与纬度、母竹胸径、笋长笋高、春笋最大直径等指标显著水平相关 ;枝叶含水率在一年中呈递减变化规律 ,但存在一个相对稳定时期 ,不同种源各月份含水率大小排序存在一定波动 ,但总体上是中带 >南带 >
The water rates in spring shoots and new bamboo of 9 provenances of Phyllostachy heterocycla cv. pubesens were measured. The results show that there are no remarkable differences in water rates in different provenances, but it is in a contrary case in different positions of spring shoots and the new bamboo twig and leaf in different months; the water rate of spring shoots has a remarkable relation with latitude, breast high diameter of mother bamboo, the length and largest diameter of spring shoots,the water rate of branch and leaf decreases during one year, but it has a stable period. In different provenances, the mean water rate of the middle zone is the largest, the second largest comes from the southern zone, and the northern zone is the smallest.
