摘要
在雷公藤种质资源圃中对雷公藤3个类型132个单株,定期进行物候观察,结果表明:雷公藤枝条1 a春、秋生长2次,以春梢为主,典型雷公藤与中间型雷公藤春梢生长集中于4月上旬至5月上旬,昆明山海棠春梢生长比典型雷公藤迟20 d左右,生长季也长,集中在4月下旬至6月下旬。典型雷公藤5月中旬始花,5月下旬盛花,6月下旬花谢,果实10月上中旬成熟;中间型雷公藤与昆明山海棠花期比典型雷公藤迟10 d左右。
Phenological observation on 132 Tripterygium wilfordii plants of 3 types in T. wilfordii germplasm garden showed that branch growth occurred in spring and autumn, especially in spring. Spring shoot of typical and intermediate form grew during April and May, but T. hypoglaucum＇s would occurred 20 days later with longer growth period. Typical form started to flower at the first ten days in May, full-bloom stage at the middle ten days of May and blossom fall by the end of June, fruit mature at October, while flowering period of intermediate form and T. hypoglaucum would be 10 days later.
