Abstract:
An experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur
during the period of May to June 2011. Effect of waterlogging and seedling age on
morphological and photosynthetic characters of eggplant was studied. Waterlogging
was imposed for 144 hours on 30 and 40 days old seedlings with the water level 8 cm
above the soil surface. Morphological and photosynthetic characters were affected
drastically after 48 hours and 72 hours of waterlogging in 30 and 40 days old
seedlings respectively and photosynthetic characters, chlorophyll content,
photosynthesis rate and transpiration rate were decreased with reduction of stomatal
conductance of CO

and the ratio were rapidly decreased after 48 hours of waterlogging irrespective of
seedlings age. Waterlogging effects became stronger with increasing the durations of
waterlogging and differ with the age of the plant.
