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.
