摘要
本文应用PV技术研究了珍珠绣线菊等7种园林绿化树种的耐旱性,结果表明:根据被试树种的初始失膨点总体渗透势(πp)值大小将树种耐旱性强弱分为4组,由强到弱分别为:珍珠绣线菊和金焰绣线菊,金山绣线菊,栾树和金枝国槐,金叶莸和红王子锦带。
The drought tolerance of seven garden species such as Spiraea thunbergii was measured and studied by means of PV technique.The results showed： According to the osmotic potential at the initial loss turgor（πp）,the seven species can be divided into four groups.And the order of the drought tolerance（from strong to weak） was： Spiraea thunbergii and Spiraea×bumalda ＇Gold Flame＇,Spiraea×bumalda ＇Gold Mound＇,Koelreuteria paniculata and Sophora japonica ＇Golden stem＇,Caryopteris ×clandonensis ＇Worcester Gold＇ and Weigela florida ＇Red Prince＇.
