Efficiency of cold hardiness induction by desiccation stress in four winter cereals

A number of defined desiccation treatments without low temperature exposure were able to induce freezing tolerance in 20 cultivars of winter cereals. A maximal degree of freezing tolerance was induced in epicotyls at 24°C in 24 hours at 40% relative humidity in rye and wheat, 7 days at 54% RH in bar...
