The present dissertation included two experiments conducted on Crimson seedless and Superior grape cvs. transplants during 2014 and 2015 experimental seasons in the Experimental Station of Faculty of Agriculture, Benha University, at Moshtohor, Qalubia Gover., Egypt. 1st experiment (factorial) aimed to study the influence of 3 saline irrigation water conc. (3000, 6000 and 9000 ppm) combined with 2 SAR level (6 & 12), while 2nd one hoped to alleviate the expected damages could be occurred in saline stressed transplants through applying some recovering substances i.e., BA, potassium sulphate, potassium silicate and magnetic iron. Fortnightly (foliar soil) added either solely or some combined to other. The influence was evaluated by determining the differences in some growth measurements (stem height & diameter), (No. of laterals & leaves/plant), (fresh and dry weight of 3 plant organs), (average leaf & total assimilation area), (total plant dry weight and top/root ratio), some leaf physiological properties (H.L.C., L.W.P. and L.R.T.) and chemical composition (shoot carbohydrate, & total sugars), leaf chlorophyll, proline and N, P, K, Ca, Mg, Na, Fe, Mn and Zn contents.
Data obtained revealed that all saline solutions decreased significantly, all growth parameters (except top/root ratio), (L.W.P. & L.R.T.), stem total carbohydrates, leaf chlorophyll, N, P, K, Mg, Fe, Mn and Zn contents. The higher salt and SAR level was more depressive. The reverse was true with top/root ratio, (H.L.C.), total sugars, leaf proline, Ca and Na contents.
On the other hand, all investigated recovering treatments alleviated relatively the aforesaid growth and chemical disorders either slightly (BA or K2SO4 spray), moderately (K. silicate soil) or considerable rate (K. silicate foliar, magnetic iron soil added and their combination particularly last one) |
