Silicon improved growth rate by altering biochemical traits of wheat under saline conditions

Silicon (si) is a constructive element for plant growth. its application plays a multiple role to increase plant growth through influencing physiological and metabolic processes in higher plants under both biotic and abiotic stresses. a hydroponic study was conducted to investigate the interactive effect of salinity and silicon (si) on plant biochemical attributes at two different growth stages by growing two wheat varieties (faisalabad-2008 as salt tolerant & millat-2011 as salt sensitive). the two salinity (100 and 200 mm nacl) and two silicon (1 mm and 2 mm h2sio3) levels were applied using ½ strength hoagland’s nutrient solution in a wire house for 30 days. it was found that si significantly increased the salt tolerance of both wheat varieties by improving the plant biochemical traits. faisalabad-2008 performed better than millat-2011at different growth stages,i.e.,(tillering and stem elongation). © 2017,pakistan botanical society. all rights reserved.
