摘　　要：为了扩大大蒜脱毒苗在实际生产中的应用,以大蒜品种徐蒜917为试材,开展了繁殖世代数对脱毒大蒜鳞茎性状和品质影响的研究。结果表明:脱毒能显著提高脱毒第2代(D_(2))至第7代(D_(7))单头蒜重和鳞茎横径,单头蒜重和鳞茎横径的指标值均是脱毒第2代(D_(2))最高,分别为77.87 g和64.87 mm;脱毒大蒜鳞茎的大蒜素、VC和可溶性蛋白含量均以D_(2)代含量最高,其次是D_(3)代,且显著高于其他处理和CK;可溶性糖和游离氨基酸含量均是D_(2)代最高且显著高于其他处理和CK。因此,脱毒有利于改善大蒜鳞茎的综合品质,以脱毒第2代最好,其次是脱毒第3代。We studied the effects of regeneration on the traits and quality of virus-free garlic bulbs with the garlic cultivar'Xusuan 917',aiming to promote the application of virus-free garlic seed bulbs in production.The results showed that the pretreatment for free virus increased the weight and transverse diameter of each bulb from the second to the seventh generations(D_(2) to D_(7)).The two traits in D_(2) were 77.87 g and 64.87 mm,respectively,which were the highest.The content of allicin,VC,and soluble proteins was the highest in D_(2) and the second in D_(3),which were significantly higher than those in other generations and CK.D_(2) had the highest content of soluble sugars and free amino acids,which was higher than that in other generations and CK.Therefore,the pretreatment for free virus can improve the quality of garlic bulbs,and D_(2) and D3 had better quality.
