This study was carried out at the Fac. of Agric., Benha Univ. during 2014 and 2015 seasons in an endeavour to alleviate the adverse impact of irrigation with high saline water solution on growth and some leaf physiological properties of Crimson seedless and Superior salt stressed grape transplants through anti-salt stress substances manipulation (BA at 25 mg/L, potassium sulphate at 300 mg/L, potassium silicate at 5 ml/L and magnetic iron at 5 g/transplant). The collected data proved that there was a significant increment including all investigated growth parameters (plant height; stem diameter; number of lateral shoots; total number of leaves/transplant, fresh and dry weight of the different plant organs, leaf and total assimilation area, total plant dry weight and top/root ratio). Hard leaf character (H.L.C.), was significantly decreased, however, the reverse was detected in both leaf water potential (L.W.P.) and leaf relative turgidity (L.R.T.) as compared with control. The maximum improvement of both investigated parameters was achieved when the transplants were sprayed with potassium silicate at 0.5% along with magnetic iron at 5 g/transplant both soil application applied twice monthly during both seasons of study. |
