摘要
对几种苹果砧木嫁接的四年生苹果树新梢及叶的特性进行了研究。结果表明,八棱海棠砧苹果树新梢和叶的总生长量高于用各类矮化砧木嫁接的苹果树。各矮化砧苹果树中短梢及其上叶的总生长量占全树新梢及叶总生长量的比例,高于乔砧树;矮砧树中短枝的单枝鲜重、比枝重、单枝叶数、单枝叶面积、单枝叶鲜重等指标,高于乔砧树。这是矮砧树树冠小、易成花结果的主要原因。以两个矮化砧木双重嫁接的苹果树,各类枝的质量明显好于以其中一个砧木嫁接的苹果树。
The shoot and leaf characteristics of4-year-old apple trees grafted on different stocks were studied.Results showed that the total quantity of shoot and leaf on rootstock of M.micromalus Mak.was larger than those on dwarf stocks.The growth amount of fruit spur and the leaves on them of apple trees grafted on dwarf stocks were much higher in comparison with those grafted on seedling stock.The indexes of the weight of the medium and short twigs,the leaf number,the leaf area and the leaf fresh weight of the medium and short twigs are much higher than those on seedling stock.These might be the reason why the apple trees grafted on dwarfing stocks easily form plenty of flower bud.The twig quality of the trees double grafted with dwarf stocks are better than with one dwarf stock.
