兼性单性结实番茄Severianin,RP75/59,PSet 1,Oregon Spring和Santiam可在不利环境条件下自然结果,但用植物生长调节剂点花能显著促进结果,而非单性结实番茄在相同条件下自然坐果率极低。人工蕾期辅助授粉能显著提高单性结实番茄的坐果率和单果种子数,并降低其单性结实率。去雄处理导致 Severianin和Oregon Spring的坐果率显著降低,而去雄同时授无生活力花粉能使 RP75/59的坐果率显著提高,但这两处理对其它品种的坐果率无明显影响。单性结实番茄的单果重与果内有无种子以及种子多少无明显相关,但大果型品种OregonSpring无籽果实有更高的平均单果重。
Parthenocarpy tomato Severianin, RP75 / 59, PSet 1, Oregon Spring, and Santiam were found to be natural under unfavorable environmental conditions but spotted with the plant growth regulator significantly improved the results, whereas non-solidified tomato under the same conditions Under the natural setting fruit rate is very low. Artificial bud assisted pollination can significantly improve the fruit firmness and fruit number of single-fruited tomatoes, and reduce the rate of heritability. The results showed that the fruit setting rate of Severianin and Oregon Spring decreased significantly, while the fertility rate of RP75 / 59 was significantly increased at the same time of removing male pollen. However, these two treatments had no significant effect on the fruit set rate of other varieties. There was no significant correlation between the fruit weight and the number of seeds in the fruit of unisexual tomato, but the fruit weight of the fruit type OregonSpring had higher average fruit weight.
