【摘要】 利用HaR培养基,从16份向日葵自交系的下胚轴外植体上诱导出愈伤组织并得到再生芽;比较了可再生性愈伤组织和非再生性愈伤组织形态特征上的差异;探讨了添加KNO₃对愈伤组织生长速率的影响,以及向日葵体细胞外植体植株再生对植物激素的要求。更多还原

【Abstract】 Plantlets were successfully regenerated, from call! derived from lypoctyle fexplants taken from sterilized seedlings of 1616 sunflower inbred.lines. Morphogenic characteristics of regener able calli and non-regenerable ones were comparied.Possible effects of adding extro KMO3 on c,^uf growth rates of different genotypes were also investigated. Finally, phytohpraone requirements for sunflower plant regeneration, from call! are discussed.更多还原
