摘要:
 采用滇西地区9个滇橄榄自然居群的种子开展育苗试验，定期测定其苗高、地径，应用Logistic方程拟合其生长过程，以揭示其子代苗期生长节律，为其良种选育研究及苗木产业化生产奠定基础。结果表明，各居群子代苗高和地径生长过程均呈现“S”型曲线，符合Logistic方程；各居群子代幼苗地径、高的速生期分别为70~88 d和42~60 d，前者平均比后者长28 d，两者速生期生长量占总生长量的比例均在55%以上；各居群子代苗高和地径生长特性存在明显差异，以瑞丽市半宁村居群表现最佳，其苗高和地径的速生期开始早、持续时间长，生长拐点出现早，表现出较强的适应性。
Abstract:
 A seedling cultivation trial was conducted for Phyllanthus emblica by using the seeds collected from nine natural populations in western Yunnan.Seedling height (H) and root collar diameter (RCD) were measured periodically; their growth processes were simulated with Logistic function,and growth rhythm of seedling progeny were further analyzed for these populations,aiming to provide technical supports for breeding and large-scale seedling production of this species.The results showed that the growth processes of H and RCD of seedling progenies from these natural populations of P.emblica tended to be of “S”-style curves,and fitted to Logistic equation.The fast-growing stages of the RCD and H lasted for 78-88 and 42-60 d,respectively,and RCD was in average 28 d,longer than H.The amounts of RCD and H increments during the fast-growing stage were all above 55% of the total growth.Significant differences in H and RCD of seedling progenies were observed among the populations studied.Seedling progenies from Banning Village,Ruili City (P6) performed the best,and demonstrated strong adaptability,their fast-growing stage started earlier,lasted longer,and the inflation points of their growing curves emerged earlier.
