植物激素对三樱椒愈伤组织根的分化及植株再生的影响

Effect of Phytohormones on Callus Root Differentiation and Plantlet Regeneration of Hypocotyl of Capsicum annuum L.

对三樱椒下胚轴愈伤组织的分化及植株再生进行了研究。结果表明 :(1)NAA(萘乙酸 )和BA(6 苄基腺嘌呤 )的浓度比值对愈伤组织根的分化有重要作用 ,其比值越大 ,越有利于根的分化。 (2 )细胞分裂素在苗的分化中起决定作用 ,KT (激动素 ) 2mg/L和KT 2mg/L +NAA 0 0 2mg/L +PP3 3 3 (多效唑 ) 0 0 1mg/L配合使用对苗的诱导效果最好。BA 2mg/L也可诱导苗的分化 ,但苗的分化率很低。

A study on callus differentiation and plantlet regeneration of the hypocotyl of Capsicum annuum L was made The results showed that the concentration rate of NAA/BA was very important to callus differentiation The higher the rate of NAA/BA was, the more roots the callus induced KT had a good effect on bud differentiation KT 2 mg/L or KT 2 mg/L+NAA 0 02 mg/L+PP 333 0 01 mg/L were beneficial to inducing buds BA 2 mg/L could also induce buds, but the rate was very low
