More calcium precipitates were located in the epidermis, endothecium and tapetum of the sterile anther than in those of the fertile anther. Longitudinal inner cell wall of the sterile anther became thicker than that of the fertile anther at the dyad stage and uninucleate pollen stage.

到四分体与单细胞花粉时期，不育花药的木质部细胞的次生加厚壁上有较多的Ca2+沉淀，连接组织中的Ca2+沉淀也大大增加，所有不育花粉外壁较厚而发育都不正常。

The sterile line of Zhenshan 97A, Baoyuan A, g37A and Peiai64S had more Ca〓 precipitatesthan those in the fertile anthers since the pollen mother cell stage (which were mainly deposited in the epidermis, endothecium and vascular bundle).

野败不育系珍汕97A、包台型不育系包源A及温敏核不育水稻培矮64S和无花粉型不育系g37A的花药均从花粉母细胞时期开始出现较多的Ca〓沉淀，主要分布在药壁外层、药室内壁和药隔中。

Brown,1773-1858 observed minute particles within vacuoles in the pollen grains executing a continuous jittery motion while examining pollen grains and the spores of mosses and Equisetum suspended in water under a microscope.

Brown，1773-1858把花粉悬浮在水中，用显微镜观察，发现花粉的小颗粒在作不停地，无秩序的运动，这种现象叫做布郎运动。

Remarks :① In 1827, Scottish botanist Brown (,1773-1858) observed minute particles within vacuoles in the pollen grains executing a continuous jittery motion while examining pollen grains and the spores of mosses and Equisetum suspended in water under a microscope .

Venus flytrap grains are more than 15 times bigger than forget-me-not ones: There's no consistent correlation between plant and pollen size.

捕蝇草花粉颗粒比勿忘草的大15倍多，在植物和花粉大小间没有一致的相关。

In Gastrochilus the lip is semiglobose-saccate with indistinct side-lobes and a much larger mid-lobe, the column is footless and the pollinia are porate, while in Saccolabium the lip is cylindrical-spurred with indistinct side-lobes and a small mid-lobe, the column has a short foot and the pollinia are solid.

盆距兰属的唇瓣为半球形囊状，侧裂片不明显，中裂片甚大；蕊柱无足；花粉团具孔隙。囊唇兰属的唇瓣为圆筒状距形，侧裂片明显，中裂片很小；蕊柱有短足；花粉团实心。

Happenstance by virtue of producing an amount of pollen that is one to three orders of magnitude greater than the amount produced by species pollinated by insects.

其途径是，制造出大于昆虫授粉的植物种类所产生的花粉量的一至三个数量级的花粉量。

The nutrients,such as V A,V E,V C,amino acid,phospholipids,glucose oxidase DNA and RNA,in the pollen of Rosa Xanthina and Hemerocallis minor are studied and the result is that the nutrients especially of V A,V E,V C,EAA,DNA and RNA are rich and the proportion is good.

通过对黄刺莓和金针花粉的DNA ，RNA ，磷脂，葡萄糖氧化酶，氨基酸，VA，VE 和VC 等重要营养成分的测定，发现这两种花粉的营养成分丰富，配比良好，特别是VA，VE，VC 和必需氨基酸的质量比较高，RNA和DNA的质量比也较高。

The ploidy of about thousand pollen plants of rice that were obtained from anther culture in vitro were studied and the homozygosity and the hereditary rule of a part of those plants derived from hybrid F1 were investigated.

对自1972年以来，通过花药培养所获得的近千株花粉植株的倍数性和部分来源于杂种F_1的花粉植株的纯合性及性状遗传规律进行了研究。
