摘　　要：为探究华中樱桃Cerasus conradinae种子萌发特性,提高种子萌发效率,文章以湖北省赤壁市野生华中樱桃的自然成熟果实为材料,研究不同储藏时间、赤霉素浓度和浸种水pH值对华中樱桃种子发芽的影响。结果表明,(1)华中樱桃种子干燥后密封置于4℃冷藏,寿命约为1 a,期间种子发芽率随储藏时间延长呈逐步下降的趋势,不同储藏时间处理发芽率差异极显著(P<0.01),储藏15个月后种子不萌发,最佳储藏时间为5个月;(2)华中樱桃种子储藏4个月后,1000、1250、1500 mg·L^(-1)赤霉素处理对华中樱桃种子发芽存在明显抑制作用,且随着浓度的增加,抑制作用增强;(3)浸种时水的pH值为6.5时,发芽率最高,为58.89%,强酸或强碱处理均不利于华中樱桃种子萌发。In order to investigate the germination characteristics and improve the germination efficiency of Cerasus conradinae seeds,this paper used the naturally mature fruits of wild C.conradinae in Chibi city,Hubei Province as materials to study different storage times,GA_(3) concentration,and pH values of soaking water on the germination of C.conradinae seeds.The results show that(1)Under the condition of being sealed and refrigerated at 4℃after drying,the life span of C.conradinae seeds is about 1 year.During this period,the germination rate of seeds gradually decreases with the extension of storage time.After 15 months of storage,the seeds do not germinate,and the optimal storage time is 5 months;(2)After 4 months of storage of C.conradinae seeds,1000,1250 and 1500 mg·L^(-1)GA_(3) treatment has an obvious inhibitory effect on the germination,and with the increase of concentration the inhibition is enhanced.(3)When the pH value of seed soaking water is 6.5,the germination rate is the highest at 58.89%.Strong acid or alkali treatment is not conducive to the germination of C.conradinae seeds.
