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。

Although not quite as permanent as perennials, many biennials re-seed themselves, becoming comparable in performance to perennials. Biennial seeds that are planted one year will not flower until the following year. Foxglove, Hollyhock and Iceland poppy are biennials. Many people think of Hollyhock as a perennial as it self sows easily.
虽然没有那么长期稳定,很多两年生植物能够自我繁殖生长,这个是能够跟多年生植物相提并论的地方,两年生植物的种子在第一年播种种植之后并不会开花直到下一年,毛地黄、蜀葵和冰岛罂粟是两年生植物,许多人把把蜀葵当作多年生植物,因为他自我繁殖非常容易。

Lithologic character of Eogene syste is interbedded sandstone and mudstone primarily, including the thin layer oil shale, Neocene- Quaternary system is set of rivers deposits. Based on this, through the reaserch of ateral correlation and distribution characteristics of every structural layers show that: Paleozoic synthem overall thickness of relatively stable.The residual thickness of Mesozoic synthem is difference in the horizontal, Residues in the horizontal thickness of greater difference, to the greatest thickness achieve to 4500m. Eogene syste has obviously fault depression basin deposition characteristic, the thickness of many sags achieve to 3000 m ,from Neocene, the stratum crosswise mop tended to be stable.
