PROLINE CONTENT IN SPROUTING SEEDS OF BUCKWHEAT AND THEIR QUALITY UNDER ACTION OF PULSE PRESSURE AND LOW TEMPERATURES
A.V. Shilenkov, N.G. Mazei, E.E. Nefed’eva, V.N. Khryanin
The authors determined the proline content in seeds, their germinating capacity and pro-ductivity of obtained plants in buckwheat (Fagopyrum esculentum Moenсh., the Aromat variety) after treatment by pulse pressure (PP) and low temterature. At the PP of 11 MPa the proline content raises in seeds to 1.5-4.0-fold and the increase of productivity is 12 %. The action PP of 29 MPa causes the inhibition of growth, proline metabolism and death to 28 % of seeds; at the same time the productivity of obtained plants raised on 53 %. The temperatures +4 and 0 oC during 24 hours result in inhibition of germinating capacity and productivity, the temperature -4 oC result in the death more than 90 % of seeds in spite of 2.5-fold increase in proline content. PP of 11 MPa promote to adaptation of seeds to action of low temperature, 29 MPa — increases the damaging effect.
Key words: Fagopyrum esculentum Moench., pulse pressure, low temperature, proline, plant growth and development, fruitage
