研究了不同浓度6 - BA溶液对甜瓜幼苗生长、POD活性及幼苗抗逆性的影响,结果表明:各种不同浓度的6- BA对甜瓜幼苗的作用以30 mg/L和50 mg/L为较突出,其中浓度为50 mg/L时的效果最佳,不仅可显著增加甜瓜幼苗的POD活性,而且对根系生长有明显的抑制作用,通过控制幼苗的生长,使内部细胞分裂增加、POD活性增强,从而提高其对外界的抗逆性.此外,浓度为20～30 mg/L也可作为一个不错的备选范围,其综合效果虽然不如前者,但对甜瓜幼苗生长的抑制作用也较大.
The effects of different concentrations of 6 - BA on the growth, POD activity and adversity resistance of melon seedlings were studied. The results showed that it got good effect when 6 - BA concentration was 50 mg/L or 30 mg/L, especially applying 50 mg/L 6 - BA got the best comprehensive effect, it could not only significantly increase the POD activity, but also obviously restrain the root growth of melon seedlings, thus it could enhance the resistance of melon seedlings to outside adversity. Moreover, applying 20 ~ 30 mg/L 6 - BA also had better comprehensive effect and greater inhibitory action to the growth of melon seedlings.
