Study on Preparation and Fusion of Protoplasts from Avena fatua

[ Objective ] The aim was to study the preparation and fusion methods of protoplasts from Avena fatua. [ Method J Protoplasts of A. fatua were prepared by mechanical method, and the fusion of protoplasts was studied by the PEG - induced fusion combirt~d with high Ca2＋ - high pH solution wishing method. [ Result ] More protoplasts could be prepared when the leaves of A. fatua were steeped in 35 % sucrose solu- tion for at least 15 min; The protoplasts could be fused effectively by the PEG combined with Ca2＋ - high pH fusion method. [ Conclusion] The technology had laid a foundation for the preparation and fusion of protoplasts of plant cells.
