Effects of Seed-soaking with Triadimefon on the Seedling Quality and Partial Physiological Activities of Vigna unguiculata Seedling

[Objective] The aim of the research was to provide the basic data for discussing the application universality of triadimefon and its effect mechanism further.[Method] The effects of seed-soaking with different concentrations (0, 10,20,30,40 mg/L)of triadimefon on the seedling quality,the contents of chloroplast pigment,proline and soluble protein in Vigna unguiculata seedlings were studied.[Result] After soaking seeds with 10,20,30,40 mg/L of triadimefon,the plant height of V.unguiculata seedlings was obviously restrained,the ration of root to shoot was significantly increased and the root length was decreased to different extent.Except 10 mg/L,the leaf area of V.unguiculata seedlings after seed-soaking with other concentrations of triadimefon was significantly decreased and the chlorophyll content was increased with the seed-soaking effect of 30 mg/L being best.The contents of proline and soluble protein in V.unguiculata seedlings were both increased with the rise of the seed-soaking concentration of triadimefon,with the concentration of 30 mg/L reaching the maximum.[Conclusion] Soaking seeds with triadimefon solution had better promotion effect on the growth and development of V.unguiculata seedlings with the optimum concentration of 30 mg/L.
