摘要
采用盆栽方法 ,对黑龙江省和吉林省的 15份早熟大豆品种、14份中熟大豆品种和 12份晚熟大豆品种的根系性状进行了比较研究 ,结果表明 :不同生育期大豆品种根系性状存在差异。晚熟品种根系最发达 ,其次是中熟品种 ,早熟品种根系相对最不发达。不同生育期大豆品种根系性状的差异在苗期表现不明显 。
Using pot experiment , we did a comparative study on the root characteristics among 15 early maturing,14 medium maturing and 12 later maturing soybean varieties. The results showed: There were differences in the root characteristics among soybean varieties of different maturities. The root system of the later maturing varieties was best developed, the next was that of the medium maturing varieties, while the root system of the early maturing varieties was relatively least developed. The difference of the root characteristics did not show obviously in seedling stage
