The sea ice frozen on polar ocean forms a new interface between the upper ocean and the lower atmosphere. Sea ice plays an important part in the climate and environment system of Earth through its modifying role in radiative and energy balances, prevent the exchange of heat and moisture between the ocean and atmosphere. The salt reject during processes of sea ice freezing affects the ocean structure and circulation. Sea ice also affects the weather and climate at the South Ocean and Antarctic continent.

在极区，海冰的形成在海洋上部和大气下部之间构成了新的交界面，改变了大洋表面的辐射平衡和能量平衡，隔离了海洋与大气之间的热交换和水汽交换；海冰冻融过程影响着大洋温、盐流的形成和强度；海冰对南大洋和南极大陆气象、气候有重要的影响，在气候环境系统中起着重要的作用。

During about twenty years till now, the plentiful and substantial achievement of the research on polar microbiology was obtained by Chinese scientists. The areas surveyed included the locations of great wall station and Zhongshan station, and their surrounding country and air, water, the waters of the southern ocean, Antarctic region, Bering Sea and Chukchi Sea etc, the Arctic Ocean, the living and nonliving materials and Qinghai-Tibet plateau.

中国自行组建的极地微生物学调研起始于上世纪80年代初，迄今20余年来，中国极地微生物学研究取得了丰硕的成果，调查范围涉及南北极，包括南极长城站、中山站及其附近区域土壤、空气、水体和南大洋水域，及从中取得的生命和非生命材料、白令海和楚科奇海、波弗特海、加拿大海盆等北冰洋海区，及青藏高原等等。

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。
