Abstract

Pot experiment was carried out at Faculty of Agriculture, El Bostan, Alexandria University in order to estimate the response of pea plant (Pisum sativum L., variety Master B) grown in sand culture under salinity stress to foliar application by kinetin or gibberillic Acid (GA3).        Seeds of pea were sown in plastic pot of 20 cm diameter and 30 cm depth containing 10 kg prewashed sand. The water of irrigation consisted from base nutrient solution of Hoagland containing 0, 25, 50 and 100 mM NaCl. After three weeks from sowing, the plants were foliar sprayed by 0 , 25 and 50 mg. kinetin l-1 or by 0 , 50 and 100mg. GA3l-1. Samples of plants were collected after 38 and 88 days from sowing.          The obtained results showed significant decrease of the growth characters of 38 days old plant with increasing salinity. At 100 mM NaCl treatment, the relative decrease of shoot F.W. was 59.0% and that of root was 71.7%. There were also significant decreases of Chl b, and carotenoids and significant increase of proline contents with increasing salinity.         There were no significant stimulating effects due to foliar application by kinetin on all growth characters, Chl a, Chl b and proline contents. However, foliar application by GA3 improved growth characters, at each salinity level, of 38 days old plants. However, there were significant reductions in grains F.W. of 88 days old plant with foliar application of GA3 at each level of salinity treatment.
