【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。更多还原

【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.更多还原
