摘要
以烟草品种G80为研究材料,在盆栽条件下研究了干旱胁迫对烟草水分代谢及其产量的影响。结果表明,在所选的4个不同生育期中,第一、二生育期经受干旱胁迫,使烟草上、下层单叶质量和上、下层叶质量显著减轻,上层叶质量/下层叶质量比值也降低,对烟草的产量和品质影响最大。
Effects of water deficiency on tobacco leaf water metabolism and yield were studied under pot experiment conditions, using G80 species as materials. The results show that the upper and lower single leaf weight and the upper and lower leafs weight decreased dramatically when water deficiency occurred during the first and the second bearing stage, either the upper leafs weight/the lower leafs weight was, and there were the mast effects on yield and qualities of tobacco.
