目前生产中应用的苹果矮化砧基本上是M_(26)和MM_(106)。M_(26)作中间砧的苹果树,中央领导干弱;MM_(106)作中间砧的苹果树,早果性及早期丰产性差。为了寻找新的矮化砧取代它们,1988年我所从荷兰引进了一种新的矮化砧——Mark,并利用它和上述2种矮化砧嫁接乔纳金树,进行对比试验。
Apple dwarfing anvil currently used in production is basically M_ (26) and MM_ (106). M_ (26) for the middle anvil apple trees, the central leadership of the weak; MM_ (106) for the middle anvil apple tree, early fruit and poor early yield. In order to find new dwarfing ancestors to replace them, in 1988 I introduced a new dwarfing anvil from the Netherlands - Mark, and used it and the two kinds of dwarfing grafting grafted Jonathan tree for comparison tests.
