Abstract
A pot study was conducted using Hoagland nutrient solution under green house conditions to measure water relations of two wheat varieties viz; Pak-81 and LU-26S over a range of external water stress (-3 and -6 bar) alongwith growth measurements. Wheat seedlings were subjected to water stress treatments for a period of 7 days. Fresh weight, dry weight, shoot length and relative growth rate decreased significantly with increasing stress level; LU-26S showed less reduction as compared to Pak-81. Water relation parameters decreased significantly with increasing level of stress in both the cultivars, however at higher stress level, Pak-81 maintained higher water potential and turgor pressure than LU-26S.
