芽大小、6苄氨基嘌呤和活性炭对红掌芽生长的影响

    Effects of Bud Size, 6-BA and Activated Charcoal on the Bud Growth of Anthurium Andraeanum

    • 摘要: 在无外源生长素条件下,以粉冠军红掌无菌苗为试材,研究芽大小、6-苄氨基嘌呤(6-BA)和活性炭(AC)对红掌芽生长的影响。结果表明:芽大小对红掌的出愈率、腋芽率和腋芽数的影响不显著,长芽生根数显著或极显著高于短芽。在添加6-BA 0.25~1.00 mg·L-1条件下,粉冠军红掌长芽生根率极显著高于短芽,短芽新叶数极显著高于长芽。单独使用6-BA 0.25~1.00 mg·L-1 时,长芽鲜愈量极显著高于短芽,而且红掌的出愈率、鲜愈量、腋芽率、腋芽数和新叶数极显著提高,生根率极显著降低,生根数显著或极显著降低。AC 1.0 g·L-1对试验指标无显著性影响,但能使6-BA 0.25~1.00 mg·L-1无法正常发挥作用。综上所述,在无外源生长素条件下,芽大小、6-BA和AC对粉冠军红掌芽的生长均有一定的影响,在红掌组织培养上要慎用AC。

       

      Abstract: By taking the aseptic seedlings of Anthurium andraeanum 'Pink Champion' as the test materials, the effects of the bud size, different concentrations of 6-Benzylaminopurine (6-BA) and activated charcoal (AC) on the bud growth of Anthurium andraeanum were studied under the condition of no exogenous auxin. The results showed that the size of bud had no significant effect on the callus rate, axillary bud rate and axillary bud number of Anthurium andraeanum, while the rooting number of long bud was significantly or extremely significantly higher than that of short bud. Under the condition of adding 0.25-1.00 mg·L-1 6-BA, the rooting rate of long bud was extremely significantly higher than that of short bud, and the number of new leaves of short bud was extremely significantly higher than that of long bud. When only adding 0.25-1.00 mg·L-1 6-BA,the fresh callus amount of long bud was extremely significantly higher than that of short bud, and the callus rate, fresh callus amount, axillary bud rate, axillary bud number and new leaf number of Anthurium andraeanum was extremely significantly increased, while the rooting rate was extremely significantly decreased and the rooting number of Anthurium andraeanum was significantly or extremely significantly decreased. 1.0 g·L-1 AC had no significant effect on the test indexes, but could make 0.25-1.00 mg·L-1 6-BA function normally. In conclusion, under the condition of no exogenous auxin, the bud size, 6-BA and AC had certain effects on the bud growth of Anthurium andraeanum, and AC should be cautiously used in the tissue culture of Anthurium andraeanum.
