摘　　要：为探究茉莉酸甲酯(Methyl jasmonate,MeJA)对细基江蓠繁枝变种(Gracilarla tenuistipitata v.liui Zhang et Xia)生长的影响,以细基江蓠繁枝变种外植体为试验材料,设置4种茉莉酸甲酯(MeJA)浓度梯度(0μmol·L^(-1)、10μmol·L^(-1)、20μmol·L^(-1)、30μmol·L^(-1)、40μmol·L^(-1)),添加到盐度为25‰的MES培养液中,研究其对细基江蓠繁枝变种生长的影响。结果表明,低浓度的茉莉酸甲酯对细基江蓠繁枝变种生长具有促进作用,茉莉酸甲酯(MeJA)添加浓度为20μmol·L^(-1)时,细基江蓠繁枝变种外植体的出芽率和增重率均高于其他处理组。综合各项指标得出盐度为25‰的MES培养液中添加20μmol·L^(-1)MeJA,生长最好,为细基江蓠繁枝变种人工养殖产量的提高提供了一种新的方法。To study the effects of methyl jasmonate(MeJA)on the growth of Gracilarla tenuistipitata v.liui Zhang et Xia,the explants of Gracilarla tenuistipitata v.liui Zhang et Xia were used as the experimental material.Four MeJA concentration gradients(0,10,20,30,40μmol·L^(-1))were set to add to the MES culture medium with salinity of 25‰to verify its effect on Gracilarla tenuistipitata v.liui Zhang et Xia.The result indicates that low concentration of methyl jasmonate can promote the growth of Gracilarla tenuistipitata v.liui Zhang et Xia.When the concentration of MeJA was 20μmol·L^(-1),there were significant differences in the germination rate and weight gain rate of the explants of Gracilarla tenuistipitata v.liui Zhang et Xia compared with other treatment groups.The conclusion is that according to the comprehensive indexes,the MES culture medium with salinity of 25‰and 20μmol·L^(-1) MeJA had the best growth.
