摘要：在云南西双版纳对8个大果紫檀种源的苗期生长表现进行了研究,结果表明:大果紫檀种源间地径、苗高和径高比差异均极显著,越南种源的地径生长与绝大多数的泰国种源(MT5种源除外)差异不显著,但其苗高生长显著低于泰国种源,其径高比显著高于泰国种源;大果紫檀各种源的生长表现与其产地的经纬度呈现明显的相关性;以MT2和MT3泰国种源生长最快,可初步视为优良种源;大果紫檀各种源苗高生长均在2～5月份缓慢加快,6月份则生长迅速加快,与当地月最低气温有关。大果紫檀是一个典型的热带树种,在我国宜选择春季月最低气温较高的地区引种。
Eight provenances of Pterocarpus macrocarpus were introduced to Xishuangbanna Prefecture, Yunnan Province, China, so as to study their seedling growth performance. It showed that there was great significant differences among provenances in ground diameter, seedling height and ratio of ground diameter and height, respectively; the diameter of provenances from Vietnam was not significant different from that of ma）ority of provenances from Thailand except for Provenance MT5, while their seedling height was significant lower and ratio of height and diameter was significant higher than that from Thailand; the growth performances of these provenances were remarkably related to longitude and latitude of their sources; among these provenances, Provenance MT2 and MT3 grew fastest and could be preliminarily considered as excellent provenances; the seedlings of all sorts of provenances grew slowly from February to May, and grew much fast in June, which was perhaps due to monthly lowest air temperature in local nursery. P. macrocarpus is a kind of typical tropical tree species, and is suggested to introduce to areas with high monthly lowest air temperature in spring and autumn in China.
