摘要
Abstract
Seedling growth of Annona squamosa within one year were observed and their biomass accumulation and allocation were investigated,based on which,the models for seedling growth and consecutive growth were developed. According to the developed models,the seedling growth could be divided into four stages:initial growth,fast growth,slow growth and stagnancy. During the fast growing period,the increments accounted for 67. 38% ,70. 33% of the total annual increments for height growth and basal diameter growth respectively. The developed model for biomass accumulation and height and basal diameter revealed significant correlation between plantlet drymass,above-ground drymass,plantlet moisture content and the moisture content of the above-ground part and seedling height as well as basal diameter. Seedlings of 210 days could pile up drymass 7. 39 g,which consisted of above-ground drymass 4. 86 g and below-ground drymass 2. 53 g. While the weight of the plantlet water content was 1. 68 times the wight of the plantlet drymass. Appropriate cultivating measures should be taken according to the staged developmental characteristics of A. squamosa seedlings. This research providied basic data for effective cultivation of the seedlings.关键词
