Abstract
A green house experiment was designed to investigate the effect of soil salinity and gibberellic acid (GA3) on the leaf content of nucleic acid . Seeds of Zea mays L. (synthetic variety) were soaked separately for 24 hr in (50,100 and 200) ppm solution of gibberellic acid (GA3) while seeds which were soaked in distilled water served as control . Ten seeds from each treatment and the control were sown in each pots of (30×25) cm containing soil of the following electrical conductivities (1.9 , 4.3 , 10 , 14.2 and 19.7) mmoh/cm). The leaf content of RNA and DNA were determined by using the method which described by Cherry.
The results showed that :
1- DNA content in leaf increased significantly by increasing salinity up to 4.3 mmoh/cm and decreased non significantly by increasing salinity more than 4.3mmoh/cm.
2- RNA content increased significantly with increasing salinity up to 4.3 mmoh/cm and decreased significantly by increasing salinity from (10.0 to 19.7) mmoh/cm over the control (1.9 mmoh/cm).
3- GA3 increased the leaf content DNA and RNA in different level of soil salinity.
