摘要
不同组合巴西橡胶三合树在福建南部的生态条件下,其生长强度,生理代谢和抗逆能力都存在差异。本文中主要研究比较了几种橡胶三合树的生长强度,光合作用强度及其变化。研究结果表明,三合树的生长强度和光合强度明显比对照树高,不同组合三合树的生长强度和光合强度与它们的抗寒力成正相关。
This paper is a part of the studies on the physio-ecological characteristics of some kinds of'Sanheshu' of rubcr tree (H. brasiliensis), in which 'Sanheshu' indicates that the tree is integrated by two bud-graftingto unite three clones (crown clone, trunk clone and stock clone). The growth intensity and photosynthetic intensity of 'sanheshu' are distinctly higher than that in the control clones of rubber tree especially that is in the winter . there is a positive correlation between the growth intensity, photosynthetic intensity and cold rcsistnce of'Sanheshu' of rubber tree. In order of the crown clone of different rubber trees, their intensity growth and photosynthesis were as follow:71-22> = 93-14> wuxing I3> controls.
