EFFECT OF SALT AND WATER STRESS ON GROWTH AND BIOMASS PRODUCTION IN HELIANTHUS ANNUUS L.
SHAZIA HUSAIN AND SHOAIB ISMAIL
Abstract
The effect of 0.25-1.0% NaCI salinity and water stress on growth and biomass production in Helianthus annuus L, was examined. All growth parameters showed reduction under both salt and salt water stress. One percent NaCI salinity adversely affected the relative growth rate (RGR), net assimilation rate (NAR) and leaf area ratio (LAR). Salt stress together with moisture stress also adversely affected the growth rate. Plants grown both under salt or salt and water stress conditions showed a better growth response after 1 month interval followed by a decline at subsequent harvests.
