本文主要是探讨甘薯在不同水淹强度变化时,对各种品种和无性系在生根能力方面的差异.通过甘薯块根水渍的六个处理,对甘薯栽培种及其结薯能力进行了测试.结果是水培的不结薯块,土表被水淹的也不结著块.插蔓在盆罐,并局部浸在水里的,有些无性系却结薯块.叶子生根的栽培在盆罐,局部泡在有水的砂土中,也能结薯.常规栽培品种的产量,在渍水粘重土中产量是低的,但某些未经选择的无性系,却提供了极好的产量.抗性的栽培品种可以发展.水中的插蔓,在2～3天内开始生根,在两个月里生长纤维根.其数量近于插蔓.白根,或有点似花色苷色,但不积累类胡萝卜素,甚至这些根系带有亲本营养繁殖系的特点.水下部分的茎,失去叶绿素,并显出花色苷,且有亲本营养繁殖系的类胡萝卜素颜色的特征,水下茎没有膨大.
This paper mainly explores the differences of rooting ability of different varieties and clones when the sweetpotato changes in different waterflooding intensity.Through the six treatments of sweetpotato tuber waterlogging, the ability of sweetpotato cultivars and their tubers were tested. The result is hydroponic non-potato block, the surface is flooded with no knot block inserted vine pots, and partially immersed in the water, some clones are tubers. The leaves rooted cultivation in the basin Cans, partially soaked in watery sands, can also produce tubers. The yield of conventional cultivars is low in water and clay, but some of the unselected clones provide excellent results Resistant cultivars can be developed.Water inserted in the vine, rooting within 2 to 3 days, in two months to grow fibrous roots.The number is close to plug vine white root, or a bit like anthocyanin color, but Carotenoids are not accumulated, and even these roots bear the characteristics of the parental vegetative propagation line. The stems of the underwater part lose their chlorophyll and show anthocyanins with the characteristic of the carotenoid color of the parental vegetative line, Not swollen.
