| Abstract: | Summary Stress-induced free amino acid accumulation in the presence of 0.7 M mannitol has been compared in tissue cultures of moderately stress-tolerant  Chinese Spring and stress-sensitive Cappelle Desprez cultivars and in disomic chromosome substitution lines of Cappelle Desprez into Chinese Spring. The profile of amino acid accumulation was different in the two parents. The amino acid concentration of the substitution lines belonging to the A, B and D genomes, respectively, altered characteristically under stress condition. The Cappelle Desprez chromosomes associated with non-ionic osmotic stress-induced free amino acid accumulation were 5A and 5D. |
