Abstract:
This study was conducted to evaluate the response of Nitraria schoberi under sand burial. Experiment conducted with two years old sapling with four treatments ( control, 33%, 50%, 66% burial and complete burial). Result showed that the highest concentration of proline (29 mg/gfw) observed in 50% and 66% burial treatment. The lowest concentration of proline (16 mg/gfw) observed in control. The highest concentration of Oxine (0.91 mg/gfw) were measured in 50% burial treatment and the lowest concentration of proline (0.43 mg/gfw) observed in control. The heighest concentration of stem sugar (20 mg/gdw) were measured in complete burial and the heighest concentration of root sugar (40 mg/gdw) were measured in 33% burial treatment. Stem sodium content in all burial treatment was higher than control. There was not significant differences in root potassium between treatments but leaves potassium (0.83 Meq/L) significantly increased in 75% burial treatment compared to control. Increasing burial depth decreased potassium in root and leaves. The heighest concentration of leaves and root phosphorus content were measured in 33% burial treatment equal to 0.75 and 0.68 Meq/L respectively. Adventitious roots obsedved in all burial treatment but no adventitious root observed in control. Stem wet weight were 1.5 times more than ontrol in 33% burial treatment. Root fresh weight significantly increased in 33%, 50% and 75% burial treatments compared to control and complete burial treatments. It is concluded that Nitraria schoberi had vegetative and physiological adaptive responses to different burial treatment.
