畸形果产生畸形果的原因是多方面的，首先是花芽分化及发育时期生理障碍造成的。如果这一时期遇到低温、多肥（特别是氮素营养过多），水分及光照充足，生长点部位营养积累过多，正在发育的花芽细胞分裂过旺，心皮数目增多，开花后各心皮发育不均衡，就形成多心室的畸形果。另 Malformation fruit deformities are the result of many reasons, the first flower bud differentiation and development of physiological disorders caused. If this period of experience of low temperature, more fertilizer (especially nitrogen nutrition too much), adequate water and light, the growth point of excessive nutrient accumulation, the development of bud cell division is too busy, the number of carpels increased after flowering Carpel skin uneven development, the formation of multi-ventricular malformations. another
