刚冲泡时横卧水面，茶芽吸水下沉；芬尖产生气泡，犹如雀舌含珠。

The central portion of an ovule in which the embryo sac develops ;the megasporangium.

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。

In vitro micropropagation of Taraxacum formosanum Kitamura was established to get maximum shoots multiplication rate by cultivating stem-node on MS medium supplemented with BA 0.6 mg/L+ NAA 0.06 mg/L and rooting rate achieved 100% by cultivating on MS and 1/2 MS medium or it supplemented with IBA 0.2 mg/L for 3 weeks.

试验结果发现龙珠顶芽优势强，在腋芽的增殖上，於BA 0.1 mg/L + NAA 0.01 mg/L之MS培养基，虽然可获得最多芽数，但产生的腋芽数只有2.3，且高度较矮，不易切芽，建议以MS为增殖培养基；在发根方面，不管在MS、1/2 MS或是添加IBA，培养4周后，发根率均为100%。

Rhizomes without bulbils; basal leaves petiolate or sessile.

没有珠芽的根状茎；基生叶具叶柄的或无梗。

Herbs often with tuberous roots; leaf axils often with woody bulbils; female perianth with the 2 lateral lobes largest.

草本通常具块茎状的根；叶腋通常具木质的珠芽；雌花花被具大的2侧面裂片。

Leaves usually 3-5-verticillate, sometimes basal ones opposite; leaf axil bulbils often present.

叶通常3-5轮生，有时基生者对生；叶腋珠芽通常宿存。

Aims Polygonum viviparum, which is widely distributed in eastern Qinghai-Tibet Plateau in China, is a clonal plant species with two modes of reproduction, clonal propagation by below-ground rhizomes and bulbils and sexual by seeds.

珠芽蓼是青藏高原东缘广泛分布的克隆植物，具有有性和无性两种生殖方式。

In this paper, four different representative grassland types in Eastern Qilian Mountains were selected to be experimental samples. They were Polygonum meadow, Grass steppe, Swamp meadow and Kobresia meadow.

本文选取东祁连山四种具有代表性的高寒草地植被类型作为试验样地，即珠芽蓼草地，禾草草地，沼泽草地，嵩草草地。

Seven different representative vegetation types of alpine grassland in Eastern Qilian Mountains, which were Rhododendron fruticosa shrub land, Salix cupularis fruticosa shrub land, Dasiphoru fruticosa shrub land, Polygonum grassland, Grass steppe, Swamp grassland and Kobresia grassland were selected to be experimental samples.

本文选取东祁连山七种具有代表性的高寒草地植被类型作为试验样地，即杜鹃灌丛(Rhododendron fruticosa shrub land)，高山柳灌丛(Salix cupularis fruticosa shrub land)，金露梅灌丛，珠芽蓼草地，禾草草地，沼泽草地，嵩草草地。

I didn't watch TV last night, because it .
