外来入侵植物银胶菊不同部位的化感作用
Allelopathic effects of Parthenium argentatum seedling growth of three plant on seed germination and species
摘要
Abstract
Allelopathie effects of aqueous extracts and powder of different parts of Parthenium hysteroDho-rus on seed germination and seedling growth of Abutilon theophrasti, Digitaria sanguinalis, and Rapha-nus sativus were evaluated either in petri dishes or a greenhouse. The results showed that the aqueous extracts of roots, stems, leaves and fruits all had negative effects on the seed germination and seedling growth of three tested plants, while the aqueous extracts from leaves and fruits had higher inhibiting on the seed germination and seedling growth of all tested plants than those from roots and stems. A. theo- phrasti and R. sativus were more sensitive to the extracts than D. sanguinalis. This conclusion was also confirmed by testing seed germination and seedling growth of the three plants in the mixture of 25 g pow- der (from different parts of P. argentatum) with 1 kg soil in a greenhouse.关键词
