Abstract:

In order to study the individual differences of Erythrophleum fordii Oliv. plantations, to provides theory basis for selection and vegetative propagation, Selected the target trees of Erythrophleum fordii Oliv. plantations planted in 1982 in Baiyun and Shaoping test site of the Experimental Center of Tropical Forestry, Chinese Academy as the research object, measuring the DBH, tree height, under branch height and Kraft’s class of Erythrophleum fordii Oliv. to analysis the coefficient of divergence in different stands, and the growth differences between these stands. The results showed that, the coefficient of divergence in under branch height and Kraft’s class of dominant trees in four stands of Erythrophleum fordii Oliv. plantations was large, they were 0.220 and 0.360, the coefficient of divergence in the DBH and tree height was smaller than the under branch height and Kraft’s class, reached 0.151, 0.127 respectively. The difference of tree height and under branch height of Erythrophleum fordii Oliv. between the 4 stands were extremely significant and significant. The DBH distance between Shaoping test site and Baiyun1 was 1.71cm, no significant difference to the two other stands. And also no significant in the difference of Kraft’s class among the 4 stands. So Erythrophleum fordii Oliv. in Shaoping test site grew best among the four stands of Erythrophleum fordii Oliv.. According to the results of this study and the current situation of Erythrophleum fordii Oliv., indicated the importance and urgency of the study of selection and vegetative propagation.
