植物生长调节剂常酷似基因的作用,对于多年生果树作物,其特殊价值和意义在于能在今天做到传统的遗传学技术需要几十年甚至于几百年方能完成的那些工作。果树学家会同意,那些非常有希望的并且技术上可培育不需授粉就能结果的苹果新品种,其二年生果树不至于结果也不需要疏果,果实不会在收获之前落下,切条又很容易繁殖, Plant growth regulators often resemble gene functions, and their peculiar value and significance for perennial fruit tree crops is that today’s tasks that traditional genetic techniques require decades or even centuries to do. Fruit tree scientists will agree that those who are very promising and technically cultivated without pollination will be the result of new varieties of apples, its two-year fruit tree is not the result does not require thinning, the fruit will not fall before harvest, cut and Very easy to breed,
