Abstract:
Under water and NaCl stress,morphological and physiological characteristics of 1 year potted root-seedlings of Clerodendrum trichotomum were observed and tested. The results showed that the morphology and physiological indicators of C. trichotomum were obviously changed under stress.Under 14 days of sustaining natural drought stress,leaves wilted and could not automatically restored,but 60% of seedlings recovered the growth after re-watering.Under wet injury,about 60% seedlings’ lower stem leaves began to turn yellow during the 7th and 10th day after being treated in high humility condition,and the lenticels appeared in the basic stem.The leaves turned yellow and fell at the 8th day after being treated by waterlogging stress.Equal or more than 0.6% NaCl stress result in a large number of leaves loss or even death.With stress strength increasing and time prolonging,cell membrane permeability expanded gradually,at first,activity of SOD increased,but later it decreased variously,while content of proline increased obviously under high intensity stress.Comprehensive analysis showed that C.trichotomum was a highly drought-resistant,water-resistant and salt-resistant tree,but its water-resistant ability couldn’t remain for a relative long time.
