摘要
通过对不同种源印度紫檀种子处理和苗木的培育方法,得出(普文)印度紫檀平均千粒重为80.1648g,平均发芽率为79%,(海南)印度紫檀千粒重为74.096g,平均发芽率为73%;普文种源比海南种源种子早出芽3天,普文种源地上部分(平均茎)为5.24cm,地下部分(根长)平均为3.27cm;海南种源地上部分为4.62cm,地下部分平均为2.72cm。
Seedling cultivation and seed treatments from different provenances of Pterocarpus indicus Willd were compared. The result showed that Pterocarpus indicus Willd from Puwen has average thousand kernel weight of 80. 1648g and the average germination rate 79~ ,wheras those from Hainan has average thousand kernel weight 74. 096g and the average germination rate 73%. Seeds from Pu- wen germinated three days earlier compared to Pterocarpus indicus Willd of from Hainan. Above-- ground part of seedlings with Puwen＇s provenance was 5.24cm high on average, and underground part was 3.27cm long of root on average. Above--ground part of seedlings with Hainan provenance, how- ever, was 4.62 cm high on average, and its underground part was 2.72cm long.
