ZY-1砧木对欧洲甜樱桃生长结果的影响

The Effects of Growth and Bearing to Sweet Cherry on ZY-1 Rootstock

ZY - 1砧木嫁接拉宾斯、斯坦勒、先锋、雷尼尔、龙冠、大紫和红灯 ,植株生长势降低 ,试花挂果期提早。二年生试花 ,三年生开花株率和结果株率分别达到 5 2 %～ 10 0 %和 4 1%～ 95 % ;四年生开花株率和结果株率均达到 10 0 % ,最高单株产量和平均单株产量达到 1.87～ 5 .0 6kg和 0 .31～ 1.36kg。而以中国樱桃作砧木的红灯三年生才开始开花 ,四年生开花株率、结果株率、最高单株产量和平均单株产量仅分别为 6 5 %、5 1%、0 .2 5kg和 0 .0 2kg ,仅为以ZY - 1作砧木的红灯的 6 5 .0 0 %、5 1.0 0 %、13.37%和 6 .4 5 %。

Seven sweet cherry varieties, which named Labinsi, Sitanle, Xianfeng, Leinier, Longguan, Dazi and Hongdeng, were grafted on ZY-1 rootstock in order to know the effects of stock to growth and bearing of trees. The results showed that the growing power was reduced. The anthesis and bearing time was earlier than control. The biennial trees effloresced at first time. The rates of efflorescence and bearing on 3-year old trees were up to 52%～100% and 41%～95% respectively, on 4-year old trees, 100%. The highest yield per tree was 1.87～5.06kg, the average, 0.31～1.36kg. Hong Deng on Chinese cherry stock effloresced at the 3rd year. The rates of efflorescence and bearing on 4-year old trees were 65% and 51% respectively, which just were 65.00% and 51.00% of Hong Deng on ZY-1 stock. The highest and average yield per tree were only 0.25 kg and 0.02 kg respectively which just were 13.37% and 6.45% of Hong Deng on ZY-1 stock.
