Establishing an efficient regeneration and transformation system is a fundamental role to the transgenie study.Using Centennial Seedless as materials,the effects of growth regulators,explants and ablas- tin to the generation of adventitious shoots were studied and the optimal condition for regeneration and transfor- mation was determined.Results of experiments showed that,when being used alone or combined with auxins, the cytokinin TDZ is always better than BA and KT in inducing adventitious shoots.The adve...
