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。

The establishment and relaxation processes of the transient gratings, which are formed by two recording 514nm beams with different polarization directions, SS, PP, SP and ±45℃, are investigated. Using the weak absorption of the chromophores at 632. 8nm and the positive dichroism of the chromophores molecules, a kind of bi-photonic transient gratings, owing to the periodic distribution of Trans and Cis isomers, is established first time in azo-dye doped polymeric bulk sample.

In order to disclose the adaptive strategies and capacity of Potaninia mongolica Maxim, acquired during its evolution history, the whole response system, which was composed of individual morphology plasticity response, organs anatomy structure response, physiological function response of anti-arid and anti-hotness, activities of protective enzymes response, endogenous hormone adjustment response, sexual reproduction strategies response of seeding, dispreading, sprouting and renewing, asexual reproduction strategies response of clonal growth patterns, clonal growth architectures, clonal growth architectures plasticity, heterogeneous resources utilization strategies, endogenous hormone distribution in clonal organs, foraging behavior, risk-spreading, and resource sharing, individual density allocation patterns response, niche differentiation response, species connection response, allelopathy response and biodiversity components response of the plant was profoundly explored in this paper.The studies come to at least four important results:(1) Taking the sensitive response and evading strategy to adapt to environment stress, Potaninia mongolica Maxim is a successful species has lived through the long-term evolution. Nevertheless, it is narrow climate and soil niche and characteristic of vegetation reproduction which has made the plant a rare and endangered species.
