- 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, 花期和鼓粒初期差异表现明显。
- Abstract:
- Using pot ex periment , we did a comparative study on the roo t characteristics among 15 early maturing, 14 medium maturing and 12 later maturing soybean varieties .The results show ed :There were dif ferences inthe root characteristics among soybean varieties of dif ferent maturities .The root system of the later maturing varietiesw as best developed , the next w as that of the medium maturing varieties , w hile the root system of the earlymaturing varieties w as relatively least developed .The difference of the roo t characteristics did not show obviouslyin seedling stage.
