| Abstract | ||
| An experiment was conducted in the Experimental Farm of the Desert Research Center, Ras Sudr, South Sinai Governorate to study the effects of foliar applications of salicylic acid (SA) and mannitol (M) on white cabbage Kalorama F1 cv grown under saline conditions (soil and irrigation water). White cabbage seedlings were transplanted on to soil after forty days from seed sowing. Foliar applications began 30 and 35 days after transplantation for SA and M, respectively. A total of three sprays were given at an interval of 15 days. Three different foliar applications of SA (0, 75 and 150 mg l-1) and three different M treatments (0, 2000 and 4000 mg l-1) were used, in factorial randomized completely block design. Stem length, head width, head weight, total yield, vitamin C, total sugars, chlorophyll a and b, dry weight and minerals content (N, P and K) were studied. All parameters were significantly influenced by applying different SA especially 75 mg l-1, as well as application of higher dose of M (4000 mg l-1). The highest values were observed in 75 mg SA l-1 + 4000 mg M l-1 treatment. Thus, the present results revealed that application of foliar SA and MA must be performed to overcome saline stress conditions. | ||
