摘要
本文的实验结果表明:软紫草愈伤组织脱壁所需的适宜酶浓度为:0.1%果胶酶十0.25%纤维素酶;酶解处理的适宜时间与愈伤组织年龄有关:愈伤组织的适宜年龄随其继代周期、愈伤组织继代接种量而有变化。当接种量,1克/瓶,转代后7天进行原生质体分离:接种量3克/瓶,酶解材料则以培养5天愈伤组织为宜。继代周期13天和15天的比15天和15天的,适宜脱壁的愈伤组织当代培养天数要提前1天。
The result showed:0.1% Pectinase+0.25% Onozuka R-10 was of benefit to isolate calli of A.euchroma;the approriate time of enzyme treatment was related to callus age.Callus age would vary if either subculture time or callus inoculum quantity was changed.The experiment material of isolating protoplast was 7-day callus when inoculum quantity was 1 g/flask,but 5-day callus when inoculum quantity was 3 g/flask. As the suitable material of enzyme treatment,callus of 15-day and 15-day subculture period might be cultured a fittle longer than that of 13-day and 15-day subculture period.
