摘要： 摘要： 本试验采用正交试验设计方法，用甜菜碱和壳聚糖混合处理香蕉幼苗后探索该两种药剂对香蕉幼苗冷害胁迫的影响。结果表明，外源甜菜碱（BT）与壳聚糖（CTS）可以提高香蕉幼苗抗寒能力，减轻冷害对香蕉幼苗的伤害，两者的最佳比例为0.3%CTS+5mmol.L-1ol.L-1 BT，以在寒害发生前1～3天施用效果最佳。

Abstract: Abstract: In this article, the effects of betaine and chitosan on the cold resistance of banana seedlings were studied with orthogonal experimental design L9（34）. The results indicated that BT and CTS have synergistic effect on enhancing the banana seedlings cold resistance. The best time of spraying was 1~3days before cold stressed with the best scheme of drug 0.3%CTS +5mmol.L-1 BT.
