Pollen grains germinated soon after pollination. Pollen tubes grew first into the intercellular space of branched penniform stigma and then through the intercellular space of transmitting tissue into the top of the ovary, further penetrating the ovary wall and primine to the micropyle. Green fluorescence was found in both pollen and pollen tubes.

结果表明：授粉后，花粉随即萌发，花粉管进入羽毛状柱头分支结构的细胞间隙，继续生长于花柱至子房顶部的引导组织的细胞间隙中，而后进入子房，在子房壁与外珠被之间的缝隙中向珠孔方向生长，花粉与花粉管均具有明显的绿色荧光。

MgO来源于补炉镁砂和镁质炉墙在高温下的冲蚀和挥发，X射线和显微镜分析证实渣蚀带一些区域内存在粒状和针状方镁石晶体。

After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.

在1600℃热处理下，随着w(ZrSiO4)的增加，试样的体积密度增大，显气孔率变小，试样力学强度在w(ZrSiO4)为4%时达到最大值。w(ZrSiO4)为4%的试样整体显微结构致密，固相直接结合程度提高；并且方镁石和尖晶石晶粒的晶粒尺寸粗大，晶粒发育比较完整。
