Title: On Effects of Aqueous Extrace Extract from Allelopathy of Ligularia naryensis in Flower Period on Seed Germination of 4 Pasture Plants
Abstract: 【Objective】The purpose of this study was to research the spread mechanism of Ligularia naryensis in Xinjiang and the causes of grassland degradation.【Method】Effect of L.naryensis Aqueous extract on the Seed Germination of pasture plants was studied in a growth chamber in pot culture.【Result】The result showed that the roots and stem-leaf of L.naryensis inhibited seed germination and germination index of pasture plants.The inhibition of roots was stronger than that of stem-leaf.The influence of germination index was stronger than that of germination rate.The inhibiting effect became stronger with the increase of concentration of aqueous extract.The allelopathic sensitivity was in the order of Bromus inermis= Poa pratensisFestuca arundinaceaLolium perenne.【Conclusion】When the degenerated grassland of Ligularia naryensis is recovered,the first thing to be considered should be to apply the better tolerant fine grasses such as: Lolium perenne and Festuca arundinacea.
