摘要/Abstract

摘要： 在3种处理条件下对猴面包树Adansonia digitata种子进行播种育苗，观察记录种子萌发特性、苗高和地径，以及连续观察两年物候。结果表明：(1)70 ℃热水浸种发芽率和发芽势最高，分别为18.72%、6.20%。(2)苗高和地径增长呈“S”型，苗木生长分为缓慢期、速生期和停滞期；苗高和地径的速生期起点均为7月上旬，一直持续至9月上旬，在8月中旬出现苗高和地径速生点。1年生猴面包树苗高和地径可达81.9 cm和12.6 mm，苗木整齐度较好，苗木质量较高，苗木移栽成活率高达90%以上。(3)在云南元阳县干热河谷地区，2年内猴面包树苗期的物候无显著差异，生长发育正常，证明该地区是猴面包树理想的引种栽培区域之一。

Abstract: Seedling-raising experiments of Adansonia digitata seeds with three different pretreated conditions were carried out. Meanwhile, the seed germination characteristics, seedling heights, ground diameter and phenological characteristics of seedlings were observed during two years. The results showed that, (1) the highest seed germination rate and germination power were 18.72% and 6.20% by dipping in 70 ℃ water. (2)The seedling heights and ground diameter increments followed an ‘S’ type growth curve, including slow-growing stage, fast-growing stage, lag-growing stage. The seedling heights and ground diameter grow fast from early July to early September, and the fast-growing point was occurred in mid-August. While the annual growth of A. digitata seedling heights and ground diameter was 81.9 cm and 12.6 mm. The seedlings had a good uniformity and growth quality, and the survival rate of transplant could be above 90%. (3) Seedling phenological characteristics were no significant difference according to the phenological records in Yuanyang dry-hot valley areas during two years, and could growth normally, which indicated A. digitata would be introduced successfully in Yuanyang dry-hot valley areas and maybe introduced successfully in other similar areas.

Key words: Adansonia digitata, germination characteristics, growth rhythm, phenological observation
