Effect of Pretreatment Solution and Duration on Growth of Tomato Cuttings in Nutrient Solution
-
摘要: 以番茄侧枝为试验材料，研究预处理液成分及处理时间对番茄营养液扦插苗根系生长的影响。结果表明：采用CaCl2溶液进行预处理后，番茄扦插苗生长情况最好，显著高于对照处理及NAA、IBA处理，其中以200 mgL-1的CaCl2溶液处理效果最佳，其叶面积增加量、叶色指数、根长、根系活力、根数均最高；当采用CaCl2溶液进行预处理时，处理的最适时间为30 min。说明使用适当浓度的外源Ca2+进行预处理可有效促进番茄营养液扦插苗生根，并提高根系质量。Abstract: Effect of pretreatment solution and duration on the growth of tomato cuttings for propagating in nutrient solution was studied. The results showed that the cuttings pretreated with a solution containing CaCl2 grew best among all tested materials. The growth of cuttings was significantly higher than those of control, NAA and IBA. At CaCl2 200 mgL-1, the best results on the area increase and color index of the leaves as well as the length, activity, and count of the roots on the tomato cuttings were found. The optimal pretreatment duration for the propagation was 30 min. It appeared that by pretreating the cuttings for half an hour in a solution with appropriate concentration of exogenous Ca2+, root formation and quality of the tomato cuttings in nutrient solution could be improved.
