光质对火焰无核愈伤组织形成及再分化的影响

摘要

Taking the isolated leaves , petioles and stems of aseptic seedlings of Flame seedless grape as explants , we studied the effects of red light, blue light, white light and dark culture on the callus formation and redifferentiation of grape .The results in-dicated that dark culture and red light treatment were conducive to the formation of callus .After the callus of Flame seedless grape was treated with red light and white light for 50 d, the activity of SOD reached the maximum , suggesting the treated callus had larger differentiation potential .%以火焰无核葡萄无菌苗的叶片、叶柄、茎段为外植体，研究了红光、蓝光、白光、暗培养4种处理对葡萄离体再生愈伤组织形成及再分化的影响。结果表明：暗培养和红光处理有利于火焰无核愈伤形成，火焰无核的愈伤组织在红光及白光处理50 d时SOD酶活性达到最大，分化潜力较高。
