摘要
对三倍体毛白杨无性系苗期生长发育过程及其生长规律进行了初步研究,并对苗期高生长与气候因子间关系进行了灰色关联分析。结果表明,三倍体毛白杨无性系生长发育具有明显的阶段性,生长进程呈现慢-快-慢的规律,并存在明显的速生期。
Growth process and rules of clonal triploid of Populus tomentosa during Seedling Stage were studied in this paper.Using methodology of grey correlation analysis,relationship between growth in height during seedling stage and climatic factors were analyzed.Results showed that growth of clonal triploid of Populus tomentosa had significant stage.Growth process appeared the rule of slow fast slow and existed obvious fast growing period.
