以三个具有不同特点的棉花新品系为试材的研究表明，卡那霉素对棉花下胚轴的愈伤组织形成和增殖均有明显的抑制作用，随其浓度的增加，愈伤组织形成的频率降低，增殖的倍数减少；当浓度增加到１００ｍｇ·Ｌ－１时，愈伤组织严重褐化，其正常生长受到完全抑制；下胚轴形态学上端切段较下端切段更易受卡那霉素的影响
The results showed that kanamycin significantly inhibited the formation and proliferation of cotton hypocotyls. With the increase of the concentration of kanamycin, callus formed The frequency of the hypocotyls decreased and the fold of proliferation decreased. When the concentration was increased to 100 mg · L-1, the callus was browning severely and its normal growth was completely inhibited. The hypocotyl morphological upper cleavage was more vulnerable than the lower cleavage The impact of mycophenolate
