Abstract

---

A study using 21 cultivars of wheat (Triticum aestivum L) and a salt tolerant barley (Hordeum vulgare L) showed significnat variation in ∆ (discrimination against 13C during photosynthetic CO2 - uptake) among cultivars and salinity levels. Salinity reduced straw, grain weight and the average value of ∆ in all the cultivars. The reduction caused by salinity varied among cultivars. Barley had larger values of ∆ than did wheat and there was a positive correlation between ∆ and production of straw (r = 0.36), grain (r = 0.44) and total biomass (r = 0.47).
