果树主干与一年生新梢横截面积的相关研究

Studies on the Correlation Between the Cross Section Area of Trunk and One-year Current Shoots in Fruit Trees

调查了荔枝、龙眼、桃和主干横截面积与１年生新梢横截面积的相关关系，结果表明，４种果树的主干横截面积等于其上着生的所有１年生新梢横截面积之和，可以此来测定新梢的生长量。

his paper investigated the correlation between the cross section area of trunk and one-year current shoots in litchi(Litchi chinensis Sonn.), Longan (Dimocarpus longana Lour.),peach [Prunus persica(L.) Batsch]and nai(P. salicina Lindl.var. cordata J. Y. Zhang). Statistical anaiyses showed that the trunk cross section area equalled the sum of cross section area of all one-year branches growing out of the plant. These can be used to measure growth increment of one-year current shoot.
