| 摘 要： | 以粳型超级稻沈农265为试材,秋光为对照,采用盆栽方法,在不同生育时期对二者根系形态和生理特征进行比较。结果表明,沈农265在根数、总根长、根体积、根重、单株根系氧化力、伤流速度、总吸收面积、活性吸收面积等方面都表现出明显的优势。从根系的生长动态看,两品种差异主要表现在生育中后期,沈农265的根系较秋光更庞大,代谢活性更强。

| Abstract: | Root morphological and physiological characteristics of japonica super rice Shennong 265 were studied.Using Akihikari as control,root morphological and physiological characteristics were studied at different growth stages with japonica super rice Shennong 265 under pot-culture conditions.Shennong 265 was behaved significantly in root number,root volume,root total length,root weight,root oxidizing ability per plant,sap bleeding,total absorption area and active absorption area.According to the trends of root growth,the differences of the two varieties appear in metaphase and anaphase.Root of Shennong 265 was more enormous and active than that of Akihikari. |
