Trends in total lipid content of pea seeds under storage conditions

Abstract

Crop plant seeds deteriorate when stored improperly and for long periods. Thus, there is a loss of growth and vigor of aged seeds, which eventually leads to a decrease in total germ count. The decrease in vigor of young plants depends on the storage conditions, the crop species and the cultivar play a major role. Relative humidity and storage temperature are the major factors. that influence seed quality during storage. Seed deterioration is caused by loss of carbohydrate, protein, lipid, etc. Content in order to reveal the losses in lipid content, during 2017-2019, four garden pea cultivars stored under different temperature and humidity conditions were analyzed in triplicate. The obtained results highlight that lipids are influenced by both storage conditions and seed age. The data show a higher propensity to depreciation of the cultivar Gloriosa compared to Zsuzsi or Kelvedon Wonder, which denotes a better genetic capacity of both cultivars to adapt to storage conditions. The best results were obtained when seeds of these cultivars were stored at 4 °C and 8% humidity compared to 22 °C and 65% humidity.
