摘要: 烤烟NC89、LJ851、LJ911在旺长期生长迅速,耗水量大。烟株生长的最适宜土壤相对含水量应保持在75%~85%,此土壤水分条件下的中午光合速率的下降是气孔限制所致。当土壤相对含水量低于75%,光合非气孔限制因素开始出现。当土壤相对含水量低于65%时,非气孔限制逐渐成为光合下降主导因子,并可能导致光合器官受到损伤。

关键词: 烤烟, 水分胁迫, 光合速率, 气孔限制, 非气孔限制

Abstract: The flue-cured tobacco of NC89、LJ851、LJ911 grow rapidly, consume water a lot in the vigorous growing stage. The level of relative soil water content had better be kept at 75%~85%. The fall of photosynthesis rate at noon is brought by stomatal limitation. When relative soil water is below 75%, the cause of photosynthesis rate drop is non-stomatal limitation. The non-stomatal limitation play dominant role in decline of photosynthesis while relative soil water content is below 65% which could do harm to photosynthesis organ.

Key words: Flue-cured tobacco, water stress, photosynthesis rate, stomatal limitation, non-stomatal limitation
