通过比较油茶自交和异花授粉后的结构和统计特征，探讨了油茶自交不育性。虽然略有延迟花粉萌发和花粉管生长在自交子房相比，杂交子房观察，有没有显着差异的花粉萌发和花粉管生长到花柱的基部的百分比。两种授粉处理后的形态结构也没有差异。然而，自交胚珠的胚珠穿透率和双受精率显著低于杂交胚珠，表明在红山茶中可能存在一种前合子的迟效自交不亲和机制。油茶属。在自交败育胚珠中观察到胼胝质沉积，而在正常胚珠中没有。胚珠在胚胎发育过程中的解剖结构没有表现出差异，而在最终的果实和种子设置观察到显着差异。此外，败育胚珠在自交子房发生在SP后35天内和受精卵分裂之前。然而，这一过程并没有在整个生活史中连续发生，在自交败育胚珠中没有观察到合子。这些结果表明，玉米的自交不育性是由玉米的自交不育性引起的。oleifera的自交不亲和性可能是由前合子晚作用自交不亲和性（LSI）引起的。
In this report, self-sterility in Camellia oleifera was explored by comparing structural and statistical characteristics following self-pollination (SP) and cross-pollination (CP). Although slightly delayed pollen germination and pollen tube growth in selfed ovaries compared to crossed ovaries was observed, there was no significant difference in the percentages of pollen that germinated and pollen tubes that grew to the base of the style. There was also no difference in morphological structure after the two pollination treatments. However, the proportions of ovule penetration and double fertilization in selfed ovules were significantly lower than in crossed ovules, indicating that a prezygotic late-acting self-incompatible mechanism may exist in C. oleifera. Callose deposition was observed in selfed abortive ovules, but not in normal. Ovules did not show differences in anatomic structure during embryonic development, whereas significant differences were observed in the final fruit and seed set. In addition, aborted ovules in selfed ovaries occurred within 35 days after SP and prior to zygote division. However, this process did not occur continuously throughout the life cycle, and no zygotes were observed in the selfed abortive ovules. These results indicated that the self-sterility in C. oleifera may be caused by prezygotic late-acting self-incompatibility (LSI).
