【摘要】 番茄水插育苗方法,比扦插育苗方法,经济简单,管理方便。因此在番茄生产上有直接应用价值。另外水插育苗方法,可用于保存和加速繁殖选育种材料,加快番茄选育种进程。 番茄水插育苗,可利用番茄整枝时的侧枝作为插条,枝长8-12厘米,伤口经自然干燥愈合后,用生长素IAA100ppm或NAA50ppm或两者混合溶液浸泡10分钟,取出经清水冲洗再插入水中。也可直接插入低浓度IAA 0.1-0 .2 ppm的溶液中。水插温度白天保持 22-28℃,夜间保持10-18℃,经七天左右即发根成苗。更多还原

【Abstract】 The Water culture method for growing tomato seedlings is more economical, convenient and manageable than the general one. It has a directly practical value for tomato production. Moreover, it is also suitable to preserve the propagating material and to accelerate propagation and the procedure of breeding.Branches from prunning of tomato plant 8-12cm in length were retilized for cuttings in the water culture method. After the formation of callus tissue through natural drying the cutting was cultured in solution of IAA lOOppm or NAA 50ppm or their mixture for 10 minutes, then washed and cultured in water. It could also be soaked directly in low concentration (0.1-0.2ppm) IAA solution. The temperature during the experiment period maintined at 22-28℃ in day and at 10-18℃ at night. In general, roots of seedlings were formed after about 7 days.更多还原
