本试验用无病毒的金冠、国光、甜黄魁等品种苗木和幼树,进行观察研究表明,无病毒苗木比带毒苗木生长旺盛.苗木高度、粗度、叶片大小和鲜重呈极显著差异,而且苗木高度和粗度的整齐度高.无病毒幼树与带毒树比较,干周、新梢生长总量、新梢长和叶片大小均呈显著或极显著差异,同时单株花量多,产量高,果个大,比带毒树易早期丰产.
In this experiment, the virus-free Golden Delicious, Guoguang, Sweet Huangkui and other varieties of seedlings and saplings were observed and studies have shown that virus-free seedlings than the vigorous growth of vigorous seedlings seedlings height, thickness, leaf size and fresh weight was significantly different , And the seedling height and roughness uniformity.With the virus-free saplings and virulent trees, dry weeks, the total shoot growth, shoot length and leaf size were significant or very significant differences, while the single flower Many, high yield, a large fruit than the poisonous tree easy early yield.
