Пролин у растений и клеточных культур кукурузы при действии осмотических стрессов in vitro

Aim. Young corn inbred line plants and cell cultures, obtained from those lines, were cultivated under salinity (25.0 g/l sea
 water salts) or water stress (0.8 M mannitol). The role of proline in those variants was investigated. Methods. We added
 stress compounds to water or ½ Mura...

Zusammenfassung:Aim. Young corn inbred line plants and cell cultures, obtained from those lines, were cultivated under salinity (25.0 g/l sea
 water salts) or water stress (0.8 M mannitol). The role of proline in those variants was investigated. Methods. We added
 stress compounds to water or ½ Murashige-Skoog medium (for plants) to S1 medium (for cell cultures) and tested corn
 variants. The free proline levels were estimated on the 14th day of stress pressure. Results. The level of free proline rose
 in plants, cultivated on nutrition medium with the addition of mannitol and in calli tissues, cultivated under both types of
 osmotic stresses. The plant proline content elevated after the degradation of proline rich proteins, PRPs. But at the same
 time cell proline was the product of biosynthesis. Conclusions. The absolute values of proline levels are not indices of
 plant stress tolerance.
 Keywords: Zea mays, intact plants, cell culture salinity, water stress, proline.
