This study was carried out at the Fac. of Agric., Benha Univ. during 2014 and 2015 seasons in an
endeavor 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 antisalt
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. |
