激素和氮素对无籽西瓜组培中芽分化的效应
Effect of Auximone and Nitrogen on the Gemmiparous Growing in Tissue Culture for Seedless Watermelon
【摘要】 探讨了不同激素对无籽西瓜组培中芽分化的效应。结果表明,6-BA对促进芽分化有极显著作用,适用浓度为0.5~2.0mg/1;IBA对芽的生长有显著影响,适用浓度为0.5~1.5mg/1;Ad(腺素)主要是促进芽苗的伸长,适用浓度为20~80mg/l。在总氮量不变的情况下,进行了不同与比值的试验,结果显示,这两种不同形态氮素的配合使用是必需的,适用比值为0.2~1。
【Abstract】 The experiments were made to determine the optimal concentrations of auxirnones(6- BA,IHA,Ad)and the best ratio of:for the gemmiparous growing in the tissue culture. The results showed that 6- BA promoted the viviparous growing significantly with the concentra- tion of 0.5~2.0mg/l,IBA affected the bud growth with that of 0.5~1.5mg/l,Ad related to the straight growth with that of 20~80mg/l.Both ammonia and nitrate were necessary with the opti- mal ratio of 0.2~1.
