| 摘 要： | 对阿尔冈金苜蓿(Medicago sativa L. cv. Algonguin)原生质体游离和培养的最佳条件进行研究,建立其细胞融合原生质体杂交体系。以下胚轴诱导的愈伤组织为材料,研究了愈伤组织继代培养时间、酶液组合、酶解时间及酶液渗透压对原生质体游离的影响,并探讨了愈伤组织原生质体在KM8P培养基上的分裂情况。结果表明:继代12d的愈伤组织游离性最好,最佳酶液组合为2%纤维素酶+0.5%果胶+1%半纤维素酶、最佳酶解时间为12h、最佳酶液渗透压为0.55mol/L;最适宜培养苜蓿愈伤组织原生质体的培养基为KM8P+2.0mg/L2,4-D+1.0mg/LNAA。

| Abstract: | The objectives of this study were to optimize the isolation and culture conditions for protoplast of Medicago sativa L.cv.Algonguin and establish the cell fusion and protoplast hybridization system.Using hypocotyls callus as tested materials,the influences of callus derived time,enzyme combination,and enzymolysis time on protoplast dissociation were studied and the division of callus protoplasts on KM8P basic medium was discussed.The results show that the callus subcultured 12 days was the optimum free mate... |
