| 中文摘要: |
| 开花期高温是影响西番莲坐果率的重要因素之一，严重影响西番莲的产量。本文以黄金西番莲为供试材料，采用人工环境模拟和自然环境平行观测试验，分析高温胁迫对开花期西番莲坐果率的影响，发现高温强度和高温持续时间是西番莲坐果率的重要影响因子，即随着温度（≥35℃）的升高，坐果率呈下降趋势，且随着高温持续时间的延长，对坐果率产生叠加伤害。此外，短时间的高温胁迫，西番莲耐受程度更强；而长时间的高温胁迫，西番莲的耐受程度显著下降，坐果率也显著下降。因此，在推广西番莲种植必须充分考虑高温情况，科学种植。 |
| 英文摘要: |
| High temperature at flowering stage is one of the important factors affecting the fruit rate of passion fruit, which seriously affects the yield of passion (Passiflora edulia Sims) fruit. In this study, the effect of high temperature stress on the fruit rate of passion fruit at flowering stage was analyzed by artificial environment simulation and parallel observation experiment of natural environment. It was found that high temperature intensity and duration were important factors affecting the fruit setting rate of passion fruit. With the increase of temperature (≥35℃), the fruit rate showed a downward trend, and with the extension of high temperature duration, the fruit rate was inhibited. In addition, passion fruit is more tolerant to short-term high temperature stress, however, the tolerance and fruit setting rate of P. edulis decreased significantly under long-term high temperature stress. Therefore, it is necessary to take full account of the high temperature and plan in the popularization of P. edulis planting. |
