TI - Effect of gamma radiation on the changes of biochemical, morphologicial and technological characteristics for potato tubers during storage KW - Potatoes KW - Storage KW - Research KW - Gamma rays KW - Physiological effect N1 - Includes reference N2 - The investigation aimed to study the influence on gamma irradiation of postharvest potato tubers for extending their shelf-life for more than six months. Two cultivars were used i.e. Diamont and Spunta cvs., in this investigation. using two different doses of gamma irradiation i.e. 50 and 150 Gry, in addition to a control (unirradiated tubers). Thus, 18 treatments were carried out with their replications for measuring physical, physiological and microbiological characters. Percentage of sprouts rot tubers, total count of bacteria, yeast and fungi counts were determined. Moreover, chemical constituents were determined, induding moisture, dry matter percentage, total soluble sugars, ascorbic acid (vitamin C), amino acids and nucleic acids (RNA and DNA) content UR - http://nile.enal.sci.eg/EALE/2003/MUJAS/2803/8/6191.pdf ER -
