一、大型畸形果主要产生于花芽分化及发育时期,生长点部位营养积累过多,正在发育的花芽细胞分裂过旺,心皮数目过多,开花后由于各心皮发育的不均衡,而形成多心室的畸形果。防治:要选用不易产生畸形果的品种,及时摘除畸形果。育苗期间温度不宜控制过低,水分及营养必须调节适宜。

First, the large-scale abnormal fruit mainly occurs in the flower bud differentiation and development period, the growing point of nutrient accumulation is too much, the development of bud cells are over-split, the number of carpels too much after flowering because of the uneven development of the carpel, and formed Multiple ventricular malformations. Prevention: to choose not easy to produce varieties of deformed fruit, timely removal of deformed fruit. Breeding temperature should not be too low during the control, moisture and nutrition must be adjusted appropriately.
