雾培马铃薯;品种;定植节数;打顶次数
摘  要：
该试验采用L9(34)正交试验设计,研究了不同定植节数、打顶次数及品种对雾培马铃薯植株茎粗、根系、LAI,LOX活性及结薯能力的影响.结果表明:雾培马铃薯定植3节及打顶2次处理均能促进LOX活性增强、匍匐茎发生,增加块茎数量和质量;结薯能力与品种差异相关密切,品种费乌瑞它结薯能力最佳;同时发现LOX活性增强利于雾培马铃薯结薯.品种费乌瑞它结合定植3节和打顶2次为雾培结薯最优组合.

摘  要：
An L9(34) orthogonal experiment was conducted to investigate the effects of node number control in transplanting,top-pruning times and varieties on stem diameter,roots,leaf area index(LAI),lipoxygenase(LOX) activity and tuberization of potato plants in aeroponical culture.The results indicated that transplanting with three nodes or top-pruning twice enhanced LOX activity,promoted stolon formation and increased tuber number and weight and that the capacity of tuberization was closely related to variety and cv.Favorita produced the highest yield of tuber.High LOX activity was beneficial to tuberization of the plant.In conclusion,the optimum combination for increasing potato tuber number in aeroponical culture was planting cv.Favorita with three nodes in combination with double top pruning.
