Abstract

Abstract: Seedling quality plays an important role in rice growth and quality at maturity.The effects of different concentrations of rice seedling conditioner on the growth of rice seedlings (cultivar Kenjing 7) were studied in a pot experiment.The results showed that application of rice seedling conditioner can reduce plant height,increase stem width,number of roots,root length and root volume,and improve physiological metabolism (chlorophyll content,soluble protein content,soluble sugar content and peroxidase activity).A seedling conditioner concentration of 5 g/L was found to be optimal.

Key words: Rice seedlings;Seedling conditioner;Morphogenesis;Regulation effect
