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.
