Abstract
In order to explore the effect of Prunus padusleaf extract on seed allelism,used petri dish filter paper method to study the effect of Prunus padus leaf extract on seed germination and seedling growth of four recipient plants.The results showed that the Prunus padus leaf extract mainly inhibited the seeds of Raphanus sativus,Brassica rapa and Betula platyphylla,but had no obvious effect on the seeds of Trichosanthes cucumeroides.The root length of Raphanus sativus and Trichosanthes cucumeroides seedlings was mainly promoted by low concentration and inhibited by high concentration,and the root length of other receptor plants was mainly inhibited.The stem length of the seedlings of the four plants was improved.The effect of the fresh quality of Brassica rapa,Raphanus sativusand and Trichosanthes cucumeroides roots showed a trend of low promotion and high inhibition.The effect of the stem fresh quality of Raphanus sativus,Betula platyphylla and Trichosanthes cucumeroides seedlings generally showed a promoting effect with the increase of treatment concentration.When the treatment concentration was 0.04 g/mL,the effect of the stem fresh quality of Brassica rapa seedlings was more obvious.When the treatment concentration was 0.02 g/mL,the growth promotion effect of the four plants was obvious.关键词
