Salt stress is applied to plants over 105 days period. Seedling are grown in 20 by 5 cm conetainers in the greenhouse. Three harvests are taken during this period either at 49 or 28 day intervals and fresh weight of herbage recorded. Salt tolerance of accessions is evaluated by comparing herbage production under salt stress with that in an unstressed control. Two replications of the procedure are used to calculate estimates of salt tolerance during regrowth. Thus: THE HIGHER THE NUMBER THE HIGHER THE SALT TOLERANCE. Numbers above 1 are more salt tolerant than the three cultivars used as internal controls: Mesa-Sirsa, Malone and Saranac AR
