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 paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象,采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段,对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究,研究表明:个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列,岩石为辉石-角闪石-长石-绿泥石-金云母组合;本区的花岗岩为过铝质花岗岩,主要与燕山期碰撞造山作用有关,锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切;本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

Combining with the result of emasculation, bagging, artificial pollination and pollinating observation, it was concluded that L.pincina should be anthophilous flower plant under natural condition.

结合套袋实验和传粉观察结果认为:在自然条件下,滇丁香为虫媒花植物,其中针型花和线型花所接受的亲和性花粉分别为异株同型花和异型花提供。

The nano ferric oxide powder was prepared by using methyl isobutyl ketone as extractant.
