Metabolic acclimation via the accumulation of compatible solutes is regarded as a basic strategy for the protection and survival of plants in extreme environments. Certain plants accumulate significant amounts of glycinebetaine (betaine), a compatible quaternary amine, in response to high salinity, cold and drought. It is likely that betaine is involved in the protection of macrocomponents of p...

The influence of seed priming with varying levels (50 and 100 mg L?1) alpha-tocopherol (Toc) was investigated in carrot plants under water-deficit conditions. For this purpose, two cultivars carrot, DC4 DC90, were selected subjected to well-watered (100% field capacity (FC)) stress (50% FC). After 21 days conditions, a significant suppression observed shoot root fresh dry weights, their lengths...
