牛膝菊对黄山乡土植物柔毛水杨梅的化感作用
Allelopathy of invasive plant of Galinsoga parviflora on the seeds of Geum japonicum var.chinense from Huangshan
摘要
Abstract
The effects of leaching water extracted from the root, stem, and leaf of the invasive plants of Galinsoga parviflora on the seeds of the local plants Geum japonicum var. chinense were studied in this paper. The results showed that; the leaching water from different organs inhibited the rate and speed of seed germination of G. japonicum var. chinense and as the concentration of leaching water increased, the suppression increased, while the inhibition effect of the leaching water from different organs was different. The inhibition effect achieved the peak when the concentration of the leaching water of shoots, leaves and roots were 0. 1 g/mL, 0. 1 g/mL and 0.08 g/mL,respectively. When the concentration of the leaching water from all organs was less than 0.1 g/mL, the suppression increased as the concentration of the leaching water increased. However, when the concentration of leaching water extracted from shoots and leaves reached 0. 02 g/mL, the leaching water would accelerate the germination. Our study showed that the inhibition effect was the result of several compound acted together.关键词
