Abstract

The reasons for the broad distribution of Erigeron annuus in Central Russia (its biology (habitat, seed productivity, seed distribution) and its ability to exert allelopathic influence) are discussed. The following indicators were used in the experiments to assess the effect of Erigeron annuus on other species: seed germination, development rate, and length of the hypocotyl. The seeds of Erigeron annuus were found to inhibit the development of seedlings in a number of species (Trifolium pratense, Raphanus sativus, and Avena sativa). The majority of the experiments clarifying the effect of Erigeron annuus were performed on Trifolium pratense.

摘要

讨论了在俄罗斯中部广泛传播粉蝶的原因（其生物学（栖息地，种子生产力，种子分布）及其发挥化感作用的能力）。在实验中，以下指标用于评估灯盏花对其他物种的影响：种子萌发，发育速度和下胚轴长度。人们发现，灯盏花的种子抑制了许多物种（白三叶（Trifolium pratense），萝卜（Raphanus sativus）和燕麦（Avena sativa））的幼苗发育。大多数实验澄清的效果一年蓬被执行三叶草 pratense。
