摘　　要：为确定培育健壮甘蔗幼苗的合适水培营养液配方,以新台糖22号(ROC22)、粤糖55号(YT55)和粤糖60号(YT60)3个甘蔗品种为试验材料,研究了3种不同配方营养液对甘蔗幼苗株高、叶片数、根冠比、地上部干重、地下部干重、叶片SPAD值和根系活力等生长指标的影响。结果表明,新台糖22号在园试配方营养液中生长最佳,粤糖55号在改良配方和园试配方营养液中生长较好,粤糖60号在3种配方中生长均较好。因此,不同甘蔗品种幼苗的最佳营养液配方可能不一定相同。To provide suitable nutrient solution formulas for healthy growing of sugarcane,the effect of three different nutrient solution formulas on the plant height, leaf blade number, root cap ratio, aboveground dry weight, underground dry weight, leaf SPAD values, and root activity were studied with three sugarcane varieties tissue culture seedlings （ROC22, YT55 and YT60）. Results showed that ROC22 grew best in Garden Test nutrient solution, YT55 grew well in improved formula nutrient solution or Garden Test nutrient solution, while YT60 grew well in all the three nutrient solutions. Therefore, different sugarcane varieties seedlings maybe not suit to the same formulas of nutrient solution.
