摘要
以垦粳 8 号为供试品种,研究不同浓度甘氨酸(0、0.25、0.5、1.0、2.0 g/L)拌土处理对水稻幼苗形态建成和生理特性等方面的调控效果.结果表明,0.5~1.0 g/L处理均可提升水稻出苗率和出苗速度,提高叶绿素a、总叶绿素和类胡萝卜素含量,增强根系活力,促进脯氨酸(Pro)含量积累,进而增加根平均直径和根总表面积,提高株高和地上部生物量,尤其是叶片和叶鞘生物量.
Abstract
The regulatory effects of different concentrations of glycine(0,0.25,0.5,1.0,2.0 g/L)mixed in soil on morphogenesis and physiological characteristics of rice Kenjing 8 seedling were investigated.The results showed that 0.5 g/L and 1.0 g/L treatment could improve the emergence rate and seedling speed of rice,increase the contents of chlorophyll a,total chlorophyll and carotenoid,enhance root activity,promote the accumulation of proline content,and thereby increase the mean root diameter and total root surface area,and increase plant height and above-ground biomass,especially leaf and leaf sheath biomass.
