我国一些苹果产区栽培的元帅系苹果,果形较扁,萼端五棱发育不明显,未充分表现出该品种典型特点。近年为增加果实硬度和推迟成熟增加上色,应用 B9有一定效果,但有的地区第二年果形变扁。为什么元帅果实有的果形较扁、五棱不明显,既是涉及品质的实际问题,也是有关果实发育规律的理论问题。 Marshal apples cultivated in some apple-growing areas of China have relatively flat fruit shape and little pentagonal growth on the calyx side, which have not fully demonstrated the typical characteristics of the breed. In recent years to increase the fruit firmness and postpone the maturity to increase the color, the application of B9 have some effect, but in some areas the second year of fruit deformation flat. Why mandarin fruits some fruit shape is relatively flat, five edges is not obvious, not only relates to the actual problem of quality, but also the theory of the law of fruit development.
