Effects of low temperatures with and without addition of glutamic acid and sucrose on free proline content and freezing tolerance of winter wheat triticum aestivum cultivar kharkov



Effects of low temperatures with and without addition of glutamic acid and sucrose on free proline content and freezing tolerance of winter wheat triticum aestivum cultivar kharkov



Physiologie Vegetale 22(3): 305-314



Free proline increased in leaves and stem of winter wheat hardened at 1.0.degree. .+-. 0.5.degree. C, even after their separation from the roots, but thereafter began decreasing in crowns and roots undergoing same hardening conditions. After separation, the plant freezing tolerance began also decreasing, showing a very significant correlation coefficient with the free proline content of crowns. Glutamic acid added to the hydroponic culture medium, in the absence of leaves and light, increased the proline content of the crown and roots under hardening conditions, but had no effect on the freezing tolerance. The freezing tolerance increased upon addition of sucrose which had no effect on the proline content. Sucrose simultaneously added with glutamic acid had a synergistic effect on the proline content. The possibility for the roots to synthesize proline under particular conditions and relations of the amino acid with the freezing tolerance are discussed.
