阿拉伯婆婆纳水浸液对3种观赏植物种子萌发及幼苗生长的化感作用
Allelopathic Effects of Aqueous Extracts from Veronica persica on Seed Germination and Seedling Growth of 3 Ornamental Plant Species
摘要
Abstract
Taking Veronica persica as the research object,by analyzing the effects of different concentrations(20,40,60,80 g/L)of aqueous extracts from its above-ground and underground parts on the seed germina-tion and seedling growth of 3 ornamental plants,Gypsophila paniculata,Medicago sativa and Cosmos bip-innata,the mechanism of its allelopathic effect was revealed.The results showed that the aqueous extract of Veronica persica significantly inhibited the seed germination of the 3 plants,and the higher the concentration,the stronger the inhibitory effect.The inhibitory effect of the above-ground extract was greater than that of the underground part.The morphological indicators of the seedlings(embryonic axis length,fresh weight,dry weight)showed a downward trend with the increase of treatment concentration.The activities of antioxi-dant enzymes(SOD,POD,CAT)and the content of malondialdehyde(MDA)changed,indicating that the plants were subjected to oxidative stress.关键词
