摘要 [目的] 探索蓝莓组培苗瓶外扦插生根的适宜条件与技术方法。 [方法]以北高丛蓝莓“雷戈西”组培苗为材料,研究不同激素处理对蓝莓组培苗瓶外扦插生根条件的影响。 [结果]在吲哚丁酸(IBA)、萘乙酸(NAA)和混合植物生长激素(NAA+IBA )3种不同组合中,IBA生根效果最明显为61.11%,其次为NAA的53.47%,最差的为NAA+IBA的40.87%。[结论] 蓝莓组培苗扦插生根用800 mg/L的IBA最为适宜。

Abstract [Objective ]The aim was to explore the suitable conditions and technical methods of the blueberry tissue culture plants.[Method] Based on the northern high bush blueberry varieties “Legacy”,the effects of different hormone treatments on the cuttings rooting of tissue culture plants were studied.[Result] The results showed that: among the indole butyric acid (IBA), naphthaleneacetic acids (NAA) and mixed plant growth hormone (NAA + IBA),IBA had the most obvious rooting effect,the rooting percentage was 61.11%.Then was the NAA,the rooting percentage was 53.47%.The worst was the NAA+IBA,the rooting percentage was 40.87%.[Conclusion] The optimal concentration of plant growth regulator for the cutting rooting of blueberry tissue culture plants was 800 mg/L.

蓝莓属杜鹃花科(Ericaeae) 越橘属(Vaccinium L.)多年生落叶或常绿灌木,原产于北美 [1- 2]。根据栽培蓝莓生长特性的不同,可分为北高丛蓝莓、南高丛蓝莓、半高丛蓝莓、矮丛蓝莓和兔眼蓝莓5个品种[3]。蓝莓富含抗氧化剂、抑菌剂、鞣花酸、叶酸、花色素苷、类黄酮等化合物,这些物质对人体内自由基的清除、抑制及逆转人体衰老等有独特作用[4],果汁能抵抗泌尿系统感染和心脏疾病,叶酸能预防子宫癌,并对孕期胎儿的发育大有益处[5]。蓝莓具有适应性强、病虫害少、耐贫瘠[6]的特性,具有较高经济价值和广阔开发前景。
我国对蓝莓的研究始于20世纪80年代初,目前在贵州、山东、重庆等地都对蓝莓进行了引种栽培,在栽培技术和品种筛选等方面进行了一定的研究。……
