Abstract:
Taking Codonopsis pilosula seeds as experimental materials,the effects of three different brands of seed coating agents ‘Bright Shield’‘Gaoqiao’ and difenoconazole · fludioxonil · thiamethoxam 27%FSC on the growth and physiological characteristics of Codonopsis pilosula seedlings at various application rates were studied,in order to enhance the germination rate and quality of Codonopsis pilosula seedlings while reducing the incidence of seedling diseases，thereby identifying effective seed coating agents suitable for the production of Codonopsis pilosula seedlings that exhibited good disease resistance and provide reference for high-yield cultivation of Codonopsis pilosula.The results showed that compared to the CK，the ‘Liangdun’ seed coating agent significantly enhanced the germination rate，plant height，root length，and fresh root weight of Codonopsis pilosula seedlings，while concurrently reducing disease incidence.This agent promoted seed germination，seedling growth，and inhibited the development of root rot disease in Codonopsis pilosula seedlings，with the optimal application rate determined to be 16 mL·kg-1 (a4).The ‘Gaoqiao’ seed coating agent increased both the plant height and soluble sugar content of Codonopsis pilosula seedlings，inhibited malondialdehyde (MDA) levels，and boosted the activity of enzymes such as CAT，POD，and SOD，thereby fostering growth and facilitating the accumulation of soluble sugars，particularly at an application rate of 12 mL·kg-1 (b4).Meanwhile，the difenoconazole·fludioxonil·thiamethoxam 27%FSC improved the germination rate，plant height，stem diameter，and fresh root weight.It also increased chlorophyll and soluble sugar content，suppressed MDA levels，and enhanced enzyme activity，while further decreasing disease incidence and promoting seed germination and seedling growth.This agent improved stress resistance in seedlings and effectively inhibited the occurrence of root rot disease，with the optimal application rate established at 2 mL·kg-1 (c2).
