摘要
Based on the data collected on chromosome number of 1027 species and ecological environment of plants,the relationships between environmental factors and the changing rules of chromosome number,polyploidy,B chromosome were discussed.The results showed that under different light,moisture content and soil conditions,the chromosome number of plant is different in multiformity,variation extent and the highest frequency.The frequency of polyploid is relative to habitats and growing habits.The plant with B chromosome is often distributed over the subtropics and humid environment.
