Abstract

Abstract: In order to explore the difference of allelopathic potential of different extracts of Pedicularis kansuensis on several forage grasses,the effects of whole plant extracts,powder extracts and root zone soil extracts of Pedicularis kansuensis on seed germination and seedling growth of five forage seeds were investigated by laboratory bioassay. The aim is to reveal the potential of degradation of artificial grassland,and provide a theoretical basis for the restoration of degraded alpine meadow and the construction of artificial grassland. The results showed that the allelopathic effects of different extracts of Pedicularis kansuensis on seed germination and seedling growth of five forage seeds were different. The inhibitory effect of powder extracts on five forage was greater than that of whole plant extracts. The comprehensive allelopathic effect of whole plant extracts and powder extracts of Pedicularis kansuensis on the germination and seedling growth of the five graminous forage was the strongest on Festuca sinensis ‘Qinghai’and the weakest on Elymus sibiricus ‘Tongde’,and extracts of root zone soil was the strongest on Elymus sibiricus ‘Tongde’and the weakest on Elymus nutans,and moderate on other three species.

Key words: Pedicularis kansuensis, Whole plant extract, Powder extract, Allelopathic potential

摘要： 为了探讨甘肃马先蒿（Pedicularis kansuensis）不同浸提液处理对几种禾草化感潜力的差异，本研究采用室内生物测定法，研究了甘肃马先蒿植株浸提液和粉末浸提液以及根区土壤浸提液对5种禾草种子发芽和幼苗生长的影响，旨在揭示甘肃马先蒿对人工草地退化的潜在作用，为退化高寒草甸恢复和人工草地的建植提供理论依据。结果表明：甘肃马先蒿不同浸提液处理对5种牧草种子萌发和幼苗生长均有不同的化感效应，总体而言，粉末浸提液对5种禾草的抑制作用比整株浸提液的抑制作用大。甘肃马先蒿整株浸提液和粉末浸提液对5种禾草种子发芽和幼苗生长的化感综合效应表现为：对青海中华羊茅（Festuca sinensis ‘Qinghai’）的化感潜力最大，对同德老芒麦（Elymus sibiricus ‘Tongde’）最弱，而根区土壤浸提液对同德老芒麦的化感潜力最大，对垂穗披碱草（Elymus nutans）最弱，对其它3种的作用介于两者之间。
