ABSTRACT

Simarouba glauca is medicinally important oil yielding evergreen tree. A field experiment was conducted to compare the effects of PGRs ((6-BA, GA, SA, CCC, Cysteine and Methionine) with different concentrations (5 and 20 ppm) on the nitrogen metabolism of S.glauca seedlings. The results showed that PGRs significantly increased the activity of enzyme NR. The nitrate content was deceased in roots and slightly accumulated in leaves due to foliar sprays. The level of nitrogen content was increased in response to cysteine, methionine and SA after foliar spray treatment. Thus overall nitrogen fraction was well maintained in response to PGRs which will be found beneficial for overall development of s. glauca seedling.
