Longevity of seeds of oily crops

Abstract

The purpose. To determine longevity of seeds of oily crops at different temperature storage procedures and their damage. To determine intensity of seed’s respiration and factors which cause damage. Methods. Relative, analytical, field and laboratory methods. Results. At storage of seeds of oily crops in conditions of stable low positive (+5°C) or negative temperatures their longevity is preserved during the long period. At storage in conditions of variable temperatures «ex situ» the economic longevity of seeds is sweepingly lost (for 4 – 12 months). On an instance of soya bean it is shown how at various aspects and extents of damage of seeds intensification of respiration may lead to a sweeping viability loss of seeds. At modelling harvesting of corn dependences between moisture of seeds and level of their damage are determined. Conclusions. Features of preservation of longevity of seeds of sunflower, grey mustard, oily flux are determined and proved at different temperature storage procedures. Negative influence isproved of damaging seeds of soya bean and corn on their longevity.
