在仓库条件下，对 1988 年和 1989 年连续种植的两组球茎测定了伽马射线辐射和长期储存对 Valenciana sintética 14 洋葱品种化学质量的影响。在这两年中，经过辐照和未辐照的球茎在整个 300 天的储存过程中，在碳水化合物和抗坏血酸含量方面表现出相似的行为。结果发现，在储存长达 180 天的情况下，经过辐照和未辐照的样品中碳水化合物含量显着下降。发现储存时间对球茎的抗坏血酸含量没有显着影响。研究发现，1988 年种植的经过辐照和未辐照的球茎中碳水化合物和抗坏血酸的含量较高。储存时间、伽马射线辐照和特定年份均不会显着影响干物质或酸度。就总丙酮酸含量而言，伽马射线照射没有显着影响风味强度。
The effects of gamma-irradiation and long-term storage on the chemical quality of the Valenciana sintética 14 onion variety were determined under warehouse conditions in two sets of bulbs grown consecutively in 1988 and 1989. In both years irradiated and non-irradiated bulbs showed similar behaviour in terms of carbohydrate and ascorbic acid contents throughout the 300 days of storage. It was found that the carbohydrate content significantly decreased in irradiated and non-irradiated samples up to 180 days of storage. The storage time was found not to have a significant effect on the ascorbic acid content of bulbs. The carbohydrate and ascorbic acid contents were found to be higher in the irradiated and non-irradiated bulbs grown in 1988. Neither storage time nor gamma-irradiation nor the specific year significantly affected dry matter or acidity. Gamma-irradiation did not significantly affect flavour strength in terms of total pyruvate content.
