L-proline amount in callus tissues of Lancaster maize inbred lines under chloride load

摘要

Salinity of soil and soil waters are actual problems of land utilization. Chloride salinity is the most common kind; in Ukraine it is dominated by sulphate and carbonate forms. Chloride salinity has a super-negative effect on the maize plant. Growth inhibition is observed already at 0.1 % salt content in soil, but the salt level of 0.3-0.4% provokes the wilting and plant death. Numerous metabolic cell abnormalities occur under the salt influence: inhibition of enzyme activities, photosynthesis, protein synthesis, and disorders of respiratory processes (Dolgyh, Ph.D. Dissertation, 2005).
