- 摘要:
- 以常用地被植物孔雀草1 a生植株为试材，研究了其浸提液对多年生黑麦草种子萌发的影响，初步了解孔雀草对多年生黑麦草种子萌发的化感作用。结果表明：种子萌发过程中表现情况以及发芽率、发芽势等显示，孔雀草不同部位浸提液对多年生黑麦草种子萌发均具有明显的化感作用，25%的孔雀草根与茎水提液对多年生黑麦草种子萌发具有明显的促进作用，以根水提液促进效果好；其它处理的水提液对多年生黑麦草种子的萌发均起到一定的抑制作用，抑制强度为花水提液＞茎水提液＞叶水提液＞根水提液，初步认定孔雀草存在化感作用潜势。
- Abstract:
- Taking annual Tagetes patula L. as test material，the effect of Tagetes patula L.aqueous extract solution on seed germination of perennial ryegrass was studied，in order to understand the allelopathy of Tagetes patula L. on seed gemination of perennial ryegrass.The results showed that the aqueous extract solution from different parts of Tagetes patula L.all had obvious allelopathy on seed germination of ryegrass.The aqueous extract solution from root and stem of Tagetes patula L.under a concentration of 25% obvious accelerated the seed germination of ryegrass.The effect was better for aqueous extract solution of root than that of stem.However，the aqueous extract solutions under other treatments all inhibited the seed germination，with the order being flower>stem>leaf>root.These results preliminarily confirmed that Tagetes patula L.exists potentiality of allelopathy.
