Abstract
Pot-cultured tobacco plants at twelve- leaf age were treated with waterlogging in July,2003. The net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs) and intercellular CO 2 concentration (Ci) were tested on the 1st, 3rd, and 5th days of waterlogging and the recovery growth of the 1st and 5th days after 6 days of waterlogging. Pn, Tr and Gs decreased evidently with the time of waterlogging, but Ci first decreased slightly and then increased remarkably. After 5 days of the treatment, the above four indices could not be restored to the control's level. The results suggested that the photosynthesis of tobacco cultivars could be seriously affected by waterlogging and the photosynthetic damage couldn't be recovered in a short period.
