DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

Embryo sac A large oval thin-walled sac in the nucellus of flowering plants in which egg fertilization and subsequent embryo development occurs.

胚囊：是存在于显花植物胚珠珠心中的一个大型椭圆状的囊状结构，卵细胞受精和随后的胚胎发育均在这里进行。

Bead by, nucellus radical ministry and the place with bead confluent handle are called close a point , it is the place that bead handle vascular bundle enters gastrula.

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。

Ovary 2- or 3-loculed, posterior locule with 1 developed or abortive ovule or empty, anterior 2 locules each with 1 or 2 ovules.

2或3室的子房，后面的室具1发育或败育胚珠或空的，前面2子房室其中每个1或2胚珠。

The relationship between embryonic development and changes of endogenous hormones in litchi ovules was studied.

以兰竹荔枝胚胎发育时期的正常胚珠与败育胚珠为试验材料，研究了胚胎发育与内源激素的关系。
