摘要 西双版纳黄瓜（Cucumis sativus L. var. xishuangbannanesis Qi et Yuan）是我国特有的黄瓜变种资源，仅在我国云南省西双版纳州及周边地区发现有其分布。以西双版纳黄瓜为试材在北京地区分期播种，分析环境条件对其性型分化和侧枝发生的影响。结果表明：2份西双版纳黄瓜种质10号（老瓜果肉黄白色）和32号（老瓜果肉橙红色）的第1雌花节位、雌花节率和侧枝发生均与外界环境的温度和光照条件关系密切，雌花分化与侧枝发生呈明显相反的变化趋势。相关性分析表明，2份种质的第1雌花节位与日光温室月平均温度呈极显著相关，其雌花节率与累计日总辐射量呈显著负相关。西双版纳黄瓜是对低温、短日照十分敏感的黄瓜种质类型，在北京地区保护地栽培的适宜播种期为8月中下旬～翌年2月中下旬。
Abstract：Xishuangbanna cucumber（Cucumis sativus L. var. xishuangbannanesis Qi et Yuan）is one variation found only in China until now. Sowed in 8 different months in greenhouse respectively, the sex type and lateral stem of 2 germplasms were detected. The result indicated that the indexes of sex type and lateral stem development of Xishuangbanna cucumber were closely related to temperature and daylight. The development of female flowers and lateral stems of 2 germplasms expressed opposite tendency. Correlation analysis revealed a highly significant, positive association between the first pistillate flower bearing node and average temperature in greenhouse and significantly negative correlation between the percentage of nodes with female flowers to total nodes and total solar radiation. The above analysis showed that Xishuangbanna cucumbers were a kind of germplasm, which was sensible to low temperature and short daylight. The optimum sowing date in the protected field in Beijing was from the middle of August to the middle of February in the next year.
