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。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.
在含较高亲水单体的乳液聚合体系中,难以制得稳定的预乳化液,不能采用工业生产中常用的预乳化工艺,而只能采用混合单体直接滴加的方法;由于单体混合物的亲水亲油值较高,用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合,用量为单体总量的3%,且比例在6:4时,乳液聚合时具有最低的凝聚物含量和最高的单体转化率;乳液聚合反应温度升高,可以提高单体转化率,增加反应速度,但凝聚率相应提高;随着羟基单体含量的增加,聚合过程中凝聚率增加,聚合物乳胶粒平均直径增加;羧基单体有一个最佳的用量(2.6%),过高或过低凝聚率均提高;羧基含量对乳液的粘度有较大的影响,当羧基含量较低时,羧基含量增加,乳液粘度增加明显;含羟基乳液粒子由于含亲水基团较多,使得乳胶粒径增大,乳胶粒子大多数互相凝聚在一起,处于凝聚态。
