Four testing methods to detect the pollen viability of cucumber were being compared. The results indicated that I-KI staining method and acetic red dyeing were not suitable to judge the pollen viability of cucumber. Tetrazolium method can be used but the error is oversize. By and large, the Germination in vitro method was an efficient, stable and simple way to judge the pollen viability of cucumber. The component of culture medium is 10% sucrose+ 100mg/L H_3BO_3. If inoculated intraday, collect pollen of fresh abloom flower at 6:00 and if inoculated at the second day, collect before dark.

比较了4种常用的花粉活力测定方法——I-KI染色法、醋酸洋红染色法、TTC染色法和离体萌发法，认为I-KI染色法和醋酸洋红染色法不适于测定黄瓜花粉生活力，TTC染色法虽适用但误差较大，综合考虑各项因素，确定离体萌发法是最准确、简便、稳定的测定黄瓜花粉活力的方法。

The microspore was more like a tetrahedron, whilethe polar was more like a triangle. The number of microspore in every anther wasbetween 2600～3600, so the amount of pollen was quite large that it was propitiousto spread and pollination. P/O was 8088 and the breed system was singleheterosexual copulatoryb. The viability of pollen was normally above 50%. The testof pollen culture showed that the viability of pollen was up to the tiptop under thehigher temperature and lower humidity (38℃,40%),while it was weakest under thelower temperature and lower humidity (16℃,40%).The OCI is 4, and the breedsystem was belong to autocopulation. If it was heterosexual copulatory, there must beintermediums for pollination. It was recorded there were more than 40 species ofinsects on the anthotaxy or followers of Malania Oleifera. Under different weather,different living environments and different plants the frequency and rush hour of theinsects to visit the followers were different. Actions of different kinds of insect werealso different. According to the results of the observation, the form of fluid and seedof Malania Oleifera mostly rely on the action of insect pollination, especially thebees.

蒜头果的花序为聚伞形花序，有小花8～10朵，小花较小；按花粉大小等级划分，蒜头果的花粉粒属于小的范围；花粉粒呈近四面体，极面为近三角形：每粒花药所含的花粉粒在2600～3600粒之间，花粉量较大，有利于花粉的传播和授粉；胚珠比值为8088，繁育系统为专性异交类型；花粉生活力一般在50％以上；在不同温度湿度条件下测得蒜头果花粉的生活力在高温低湿(38℃，40％)的条件下最高，在低温低湿(16℃，40％)的条件下最低；杂交指数值为4，繁育系统自交亲和，异交，需要传粉者；记录到的访花昆虫有40余种，访花昆虫的访花频率及高峰时间不同，不同种类的昆虫的访花行为也是各有所异；从观察的结果看，蒜头果的种实的形成大多数依赖于传粉昆虫的活动，其中主要是蜂类。

In this experiment, 22 cucumber varieties were selected as test materials. The experiment analyzed the best method to mensurate cucumber pollen viability, the pollen viability and its influence factors, and the best low-temperature to distinguish the pollen germination rates of different varieties and compages of florescence temperature and germinarion temperature. We hope the results of experiment can offer theoretics and data to chilling tolerance varieties selection.

本试验共选取了22个黄瓜品种，研究了测定黄瓜花粉活力的最佳方法、不同黄瓜品种花粉活力及其影响因素，确定了区别不同品种花粉萌发差异的最适低温以及开花温度和萌发温度的组合，以及花粉萌发率与植株耐冷性的关系等方面，以期对耐冷性品种选育提供可以依据的理论和参考的数据。

viability：生存力

所以他(1990,1995)认为,应该用" 生存力" (viability)来代替" 真理" 一词,只要某种知识能帮助我们解决具体问题,或能提供关于经验世界的一致性解释,那它就是适应的,就是有"生存力"的(适者生存),不要去追求经验与客体的一致.

viability：生活力

种子生活力(Viability)是指种子的发芽潜在能力和种胚所具有的生命力,通常是指一批种子中具有生命力(即活的)种子数占种子总数的百分率. 种子发芽力是指种子在适宜条件下(实验室可控制的条件下)发芽并长成正常植株的能力,

viability：生存能力
