苹果短枝型品种在国外早结果早丰产的实例已有不少报导,如美国华盛顿州的罗斯维特地区,十年生金矮生(Goiden spur Delicious)亩产达2万斤。华盛顿州立大学果树研究中心1968年将米勒矮生(Miller stark spur)和普通型红星分别接在 M7、MM106、MM111及实生砧上,九年结果表明:短枝型较普通型提早结果1～2年,且产量均较普通型高。日本福
There have been many reports of examples of early sprouting of apple spur varieties in foreign countries. For example, in the area of Rosevet, Washington, USA, the annual output of Goiden spur Delicious is 20,000 kg per mu. In 1968, Washington State University Fruit Research Center attached Miller stark spur and common red star to M7, MM106, MM111 and live anvil, respectively. The results of nine years showed that the spur type had an earlier result of 1 ~ 2 years, and the output is higher than the average type. Japanese blessing
