摘　　要：研究了不同温度及赤霉素处理对盐步秋茄种子萌发与出苗的影响.结果表明,适宜其种子的萌发和出苗的温度范围为24-30℃,种子萌发的临界温度为16.67℃,有效积温范围在11～63日度,出苗的临界温度为17.13℃,有效积温的范围在13～112日度;赤霉素处理浓度在100～2005mg·L^-1对种子发芽势、发芽率和出苗率均有明显提高.Effects of different temperature and concentrations GA3 on seed germination and seeding emgergence of S. melongena L. were studied. The result showed that suitable temperature for seed germination and seeding emergence was 24~30℃, the critical temperatur of seed germination was 16.67℃, effective temperature was11~63 day degree, the critical temperature of seeding emergence was 17.13℃, effective temperature was 13~112day degree; It had remarkable effects on the germinatiing power, the germinating rate and emgergence rate of S.melongena L. with GA3 in the 100~200 mg /L.
