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。

The root system in the cortex of the host stem has a few branches and highly simplified stele of original triarch vascular bundles. The haustrium root system, which is from the root system in the cortex of a host stem enters the vascular tissues as finger-like body from the vascular rays and then to become hyphae-like body among the vascular cells.
皮层根有少数分枝,无次生结构,中柱结构高度简化,从胚根的结构可看出其初生木质部原先是三原型的;吸器根从皮层根上发生,进入寄主维管射线中,再进入维管组织内,并形成许多丝状体。

Simulium subvariegatum:北蚋
全世界已知1200多种,我国报告近90种,主要种为北蚋(Simulium subvariegatum)和毛足原蚋(Prosimulium hirtipes). 形态成虫头部的复眼明显,雄蚋的复眼较大,与胸背约等宽;雌蚋的复眼略窄于胸部,两眼间被额明显分开. 口器为刺吸式. 胸部背面明显隆起.
