摘要: 本试验在对15种植物进行了低温处理种子对植物生长和开花习性的观测研究后发现,Bromussterilis,CapsellabursapastorisMyosotisarvensis3种植物的种子经低温处理后,其开花(小穗形成)时间提前,数量增加,枝条长度增加。同时,还讨论了在全球气候变暖的条件下,植物产生的这种现象可能对该种群的繁殖和演替带来的重大影响。

Abstract: This experiment investigated the effects of pre-germination chilling of seeds of 15 species on the subsequent growth and flowering of the plants.Only three of the species (Bromus sterilis, Capsella bursa pastoris and Myosotis arvensis) markedly increased flowering after the seed chilling treatments . The shoot lengths of the seed chilled plants were also significantly greater in the three species. The ecological implications in the reproduction and succession of the population were discussed in relation to possible effects of climatic change on these species.
