摘要
研究了6-BA对酸樱桃组培苗中4种内源激素的质量分数动态变化的影响。结果表明:在培养5d时,6-BA可促进酸樱桃组培苗内源IAA和ZR质量分数的增加,也可促进内源IAA和ZR的生物合成;6-BA对内源GA3质量分数的影响与IAA和ZR相反,在培养初期,随着6-BA质量浓度的增加,GA3质量分数下降,其原因可能是高质量浓度6-BA抑制了束缚态GA3的水解,培养后期GA3质量分数大幅上升;内源ABA质量分数一直呈下降趋势,随着6-BA质量浓度的增加,下降幅度加大。
An experiment was conducted to study the dynamic changes of four endogenous hormones concentrations in tissue culture seedlings of Prunus cerasus treated by 6-BA. Results show that the high concentration of 6-BA promotes the endogenous concentrations of IAA and ZR on the fifth day of cultivation, and also speeds the biosynthesis of IAA and ZR. The endogenous hormones concentration of GA3 reduces with increasing concentration of 6-BA in the early days of cultivation. The reasons may be that 6-BA restrains the hydrolysis of bound GA3. The concentration of GA3 exhibits an obvious increasing tendency in the late days of cuhivation. The concentration of ABA shows a decreasing trend and it reduces significantly with the concentration of 6-BA increasing.
