查询词典 ligularia

Results show that the aqueous extract of 11 species could inhibit seed germination and seedling growth in Ligularia sagitta, and its effect is concentration dependent, increasing with the increase of concentration.

结果表明，11种供体植物水浸液对箭叶橐吾种子萌发和幼苗生长均有化感作用，不同浓度的水浸液对植物的化感作用强度不同，低浓度时较弱，高浓度时较强。

Seed germination rate and germination speed and seedling root length are more sensitive to the extract than the other index. Allelopathy on Ligularia sagitta is different among the species tested in this study, Thermopsis lanceolata, Stellera chamaejasme, Aconitum sinomontanum, Ipornoea cairica, Ajania tenuifolia and Wedelia trilobata show better result. New natural herbicides may be developed from these 6 species.

不同供体植物对箭叶橐吾化感抑制程度不同，披针叶黄华、狼毒、高乌头、五爪金龙、细叶亚菊和南美彭琪菊的作用效果非常显著（综合化感效应指数M0.50），这6种植物有望开发天然除草剂。

Ligulariopsis is assigned as a new genus in Compositae by a Chinese plant taxonomist in 1996, and the new genus has close relationship with Ligularia and Cacalia .

假橐吾属是1996年由我国植物学家发现的一个菊科新属，与我们研究小组多年来进行植化研究的橐吾属和蟹甲草属具有密切亲缘关系。

We measured the photosynthesis of Roegneria kamoj, Polygonumsphaerostachyum, Koeleria cristata, Kobresia myosuroides, Ligularia sagitata and Anaphalis lacteal under different soil status and investigated the variations ofcommunity composition after fertilizer to find out the mechanism ofαdiversityformation at local community level. At metacommunity level, we compared the effectsof distance and environmental gradient on the community similarity indexes of fourdifferent locations in two hills to seek the mechanism of D diversity formation.

在局域群落中，以高寒草甸植物群落的重要组分种：鹅观草、球花蓼、洽草、嵩草、箭叶橐吾和乳白香青为对象，通过施肥处理后光合能力以及群落结构的变化探讨α多样性的形成机制；在集合群落水平上，通过对比两座相距180 m山坡上4个不同坡向样方间群落相似性与距离和环境梯度的相互关系，探讨β多样性的形成机制。
