苕子人工去雄杂交授粉,由于外界条件的影响,一般成荚率只有1.6～3.4%,如花期阴天多,则基本上不能成荚.1980～1981年,我们在玻璃温室内进行苕子品种内不同组合的杂交,使成荚率提高到19.6～32.4%,最高成荚率达40%.
Prunus artificial hand-to-male hybrid pollination, due to the impact of external conditions, the general rate of pod is only 1.6 to 3.4%, such as flowering more cloudy, it basically can not be pods .1980 ~ 1981, we conducted in the glass greenhouse prickly heat Different combinations within the hybrid varieties, so that the rate of pods increased to 19.6 ~ 32.4%, the highest pod rate of 40%.
