摘要
本文以红花风铃木、黄花风铃木、金花风铃木、蓝花风铃木、洋红风铃木等5种风铃木为研究对象,通过2次调查生长性状(树高、胸径、冠幅)、保存率、开花情况等指标综合评价其生长状况,从而筛选出优良品系。结果表明:5个风铃木品种树高、胸径、冠幅、保存率存在着极显著差异,黄花风铃木和洋红风铃木在生长、保存率、开花方面表现较好,5种风铃木根据生长、开花情况优劣排序为黄花风铃木>洋红风铃木>红花风铃木>金花风铃木>蓝花风铃木。
In order to select the best species of Tabebuia, investigations of growth traits（tree height, breast height diameter, and crown width）, survivals and flowering conditions were evaluated in five species：Handroanthuschrysanthus, Handroanthuspentaphylla, Tabebuiarosea, Tabebuiapentaphylla, Tabebuiachrysantha. Analyses of variance showed that there were significant differences among the five species for height, diameter, crown width and survival.For growth, survival and flowering condition, the best two species were H. chrysanthus and T.rosea, and the 5 species were ranked in the order： H.chrysanthusT.roseaH.pentaphylla T.chrysantha T.pentaphylla.
