| 摘 要： | 应用嫁接技术建立无性系种子园,是马尾松良种繁育的主要手段之一。通过十多年来的摸索和实践,利用嫩枝接穗嫁接不论是小范围试验还是大面积生产,均表现出质量高、效果好的优良特点。广东韶关地区林科所应用嫩枝嫁接,平均成活率达84.1％以上,比老枝嫁接高2～3倍。广西贵县覃塘林场连续4年分别不同季节进行嫁接对比试验,嫩枝嫁接成活率达84.5％～100％,而老枝嫁接仅有10％～21.4％。浙江省淳安县姥山林场与开化

| Abstract: | In the paper the relationship between graft effect and external morphology, growth phase, anatomical structure and nutrient composition of tender scions of Masson Pine have been studied systematically. The results showed that if tender twig was used as scion and the needle was covered with sheath or needle just appeared, the scion was delicate and produced rich callus easily. Moreover, water and nutrient composition content of tender scion was higher and organic carbon content was smaller, which was favourable to the healing between scion and stock and the increase of survival rate of grafting. Because tender scion was at primary growth phase, the ability of cell division and differentitation was stronger, and there was larger growth increment after grafting. The above result was good proof for establishing seed orchard of Masson Pine using tender twig as scion. |
