Relationship between longans embryo development and changes of polyaminesThe thesis also studied the relationship between longan embryo development and contents of polyamines . Experiments showed that the contents of polyamines in normal ovules were higher than those in abortive ones during the whole embryogenetic process.

龙眼胚胎发育与多胺的变化研究了龙眼胚胎发育与多胺含量的关系，结果表明：正常发育的胚珠中多胺含量在胚胎发育的各个时期均高于败育胚珠。

Experiments showed that the contents of putrescine、spermidineand sperminein normal ovules were higher than those inabortive ones during the whole embryogenetic process.The highest levelswere reached 7 days after anthesis,with Put being the richest of thethree,then they declined.

试验结果表明：正常发育的胚珠中腐胺、亚精胺和精胺的含量在胚胎发育的各个阶段均高于败育胚珠，并在花后7d即达到最高值，其中Put的含量最高，随后都呈下降趋势。

On the base of review the research development in tissue culture and genetic transformation, Comparative analyses were made on the callus induction and embryogenetic abilities of anther and non-pollinated ovules of rubber tree. Fluorescence detection was implemented with the different in vitro material of Hevea brasiliensis.

本研究在综述了橡胶树组织培养及遗传转化研究进展的基础上，系统地比较了橡胶花药和未授粉胚珠愈伤组织诱导及体细胞胚胎发生能力，对橡胶树不同离体组织进行荧光背景检测，将在植物胚胎发育时期起重要作用的BBM基因导入橡胶树，对电激法转化游离小孢子细胞以及农杆菌介导花药愈伤组织进行初步探索。

Spd and Spm evidentlydropped more rapidly in the abortive ovules than those in the normal ones,which indicats that lower contents and more rapid decrease of Spd and Spmduring the embryogenetic process might have a close relationship withembryo abortion.The studies also showed that iow ratios of nn-1and nn-1might hinder embryo development.

败育胚珠中的Spd和Spm含量在胚胎败育期的下降速度显著大于正常胚珠，两者含量低以及在胚珠发育进程中较大的降幅与胚胎败育密切相关。nn-1和nn-1比值低亦不利于胚胎发育。

In a compatible pollination, pollen germinates to extrude a tube that penetrates the stigma and grows extracellularly through the stylar tissues to ovules.

当花粉通过自交不亲合的筛选后，萌发的花粉管会穿透柱头并沿著花柱朝胚珠生长。
