摘要
对江西九连山、宜丰官山、井冈山、德兴红楠种源苗期生长节律、种源间生长差异及生物量分布特点进行了研究。结果显示:4个种源生长节律相近,均为一个生长高峰;九连山种源表现最好,苗高、地径分别大于种源平均数34.39%、64.16%,表明种源选择可获得明显的增益效果;苗木不同器官间生物量分布的比率是相对稳定的,不因苗木生长量的变化而变化。
The rhythem of growth in seedling stage,growth differences and biomass distribution features between different Machilus thunbergii′s provenances in Jiulianshan Mountain,Guanshan Mountain of Yifeng,Jinggangshan Mountain and Dexing City in Jiangxi Province were analyzed in this paper.The results showed that the growth rhythm between the four provenances was highly similar,and displayed one growth peak;the provenance in Jiulianshan Mountain had best performance in the four provenances,the seedling height and ground diameter were more than the average 34.39%,64.16%,respectively.It was suggested that gain result could be acquired by provenance selection.The rate of biomasses in different organs was relatively stable,it did’t change with the growth of seedlings.
