摘要: 为探索杂草种子休眠程度与物理参数相关性,以杂草种子为试验材料,选择在农田中广泛分布、影响多种作物生长的3种杂草马唐[Digitaria sanguinalis (L.) Scop.]、牛膝菊(Galinsoga parviflora Cav.)、春蓼(Polygonum persicaria L.)进行休眠特性研究。结果表明,马唐种子的pH与其种子发芽率的线性相关性相对较好;牛膝菊种子pH、电导率与其种子发芽率的线性相关性良好;春蓼种子电导率与其种子发芽率线性相关性较为明显。

关键词: 种子休眠, 物理参数, 发芽率

Abstract: In order to explore the correlation between dormancy degree of weed seeds and physical parameters, weed seeds were selected as experimental materials and widely distributed in farmland. The dormancy characteristics of three weeds Digitaria sanguinalis (L.) Scop., Galinsoga parviflora Cav., and Polygonum persicaria L., which affected the growth of various crops, were studied. The results showed that the pH of seeds of Digitaria sanguinalis (L.) Scop. had a good linear correlation with germination rate; The seeds pH and the electrical conductivity of Galinsoga parviflora Cav. had good linear correlation with the germination rate of seeds. The linear correlation between the electrical conductivity and the germination rate in Polygonum persicaria L. seeds was obvious.

Key words: seed dormancy, physical paramenters, germinating rate
