干旱胁迫对银杏叶萜内酯年动态变化的影响
Effects of drought stress on annual dynamic changing pattern of the terpene lactones content in Ginkgo biloba leaves
摘要
Abstract
The effects of drought stress on terpene lactones contents of Ginkgo biloba grown in pots at 4 soil moisture levels under greenhouse conditions were investigated. The results showed that there were significant effects on the contents of bi-lobalide BB, ginkgolide GC, CA, CB and total terpene lactones in different growing seasons. With the development of season, terpene lactones contents were increased first and then decline at the subsequent. Moderate drought conditions can contribute to the synthesis of terpene lactones. The terpene lactones contents in mild and moderate drought conditions significantly increased if compared with the terpene lactones contents in appropriate water condition. Concerning the leaf yield, terpene lactones contents as well as the relationship between quantity and time of leaf collection, we suggested that the highest economic yield per single plant could be obtained by controlling soil water content at mild level ( relative water content ,55% -60% ) and harvesting leaves in June to October.关键词
