摘要:

为缓解草莓脱毒苗生产中部分品种茎尖数量无法满足种苗生产需求的问题,以及筛选不同草莓品种用于叶片离体诱导最适宜的叶龄,该试验以桃熏、圣诞红、隋珠、黔莓1号和越秀为试验材料,研究了叶片离体诱导培养基:基本培养基(MS)+0.5 mg·L-1 6-苄氨基嘌呤(6-BA)+1.5 mg·L-1 2,4-二氯苯甲酸(TDZ)+0.2 mg·L-1萘乙酸(NAA)中,不同草莓品种和不同叶龄的再生频率的差异。与此同时,该试验还以隋珠叶片为外植体,研究不同刻伤方式对其愈伤组织诱导的影响。结果表明,圣诞红和桃熏在MS+0.5 mg·L-1 6-BA+1.5 mg·L-1 TDZ+0.2 mg·L-1 NAA培养基条件下不定芽诱导率较高;隋珠采用叶缘叶背混合刻伤的处理方式有利于提高其愈伤组织诱导率。以上结果表明,生产中部分栽培草莓可采用同种培养基配方进行叶片离体诱导,从而提高脱毒苗生产效率;不同刻伤方式对部分草莓品种的愈伤组织数量有一定的影响,可在试验中通过选择合适的刻伤方式提高叶片的愈伤组织诱导率。

Abstract:

In order to alleviate the problem that the number of stem tips of some varieties could not meet the production demand of virus-free strawberry seedlings, and screen different strawberry varieties of the most suitable leaf age for leaf induction in vitro, Taoxun, Poinsettia, Suizhu, Qianberry 1 and Yuexiu were used as experimental materials. The effects of in vitro induction medium (MS+0.5 mg·L-1 6-BA+1.5 mg·L-1TDZ+0.2 mg·L-1NAA) on different strawberry varieties and leaf ages were studied. At the same time, the effects of different carving methods on callus induction were studied by using Suizhu leaves as explants. The results showed that the induction rate of adventitious buds in Poinsettia and Taoxun was higher under MS+0.5 mg·L-1 6-BA+1.5 mg·L-1 TDZ+0.2 mg·L-1 NAA. Suizhu is suitable for the treatment of mixed carving methods on the edge and back of leaves, which is beneficial to improve the callus induction rate. The above results showed that some strawberry varieties could be induced in vitro by the same medium which could improve the production efficiency of virus-free seedlings. The callus quantities of some strawberry varieties was affected by different carving methods. The callus induction rate of leaves could be improved by selecting suitable carving methods.
