注:对照（ ck ）坐果率为不经人工授粉、在自然条件下即开放授粉系统中所统计的坐果率。下同。 - This investigation of the two species is mainly dealing with their morphological characters , population biology , pollination biology and molecular biology , based on the following methods such as section slides , sem , artificial pollination , rapd analysis and gravity glass slides . this study is intended to demonstrate the distribution patterns of the populations for the two species , the numerical and spatial characteristics of ecological difference , the biological characters of seeds , pollination mode and reproductive stratigies , and molecular genetics . in light of the results from this study , the reasons that resulted in the present dangerous situation for the two species were discussed , and the suggestions for protecting them were proposed
本研究以种群为单位，采用石蜡切片、扫描电镜、重力玻片、人工授粉、 rapd分析等方法，对两种植物的形态生物学、种群生物学、繁殖生物学和分子生物学等方面进行了详细研究，以揭示它们的种群分布类型及成因、种群生态环境差异的数量特征和空间特征、种子生物学特征、传粉和生殖策略以及种群分子遗传特征，进而探讨两物种濒危的成因和机制，并针对性地提出了科学合理的保护对策和建议。 - The results showed that the effect of c . megacephala pollination was not significantly different from that of hand pollination and bee pollination , but significantly different from that pollinated by musca domestica l . and flies mixed by both c . megacephala and houseflies under the same density
结果表明：油菜在不同授粉方式下，大头金蝇授粉与人工授粉、蜜蜂授粉效果之间差异不显著，与家蝇授粉差异比较明显，与相同密度条件下两种蝇类混合释放有明显的差异，且有交互作用。
