以少量的硫代硫酸盐形式存在的银掺进防止绿色番茄果实成熟的蒸发气流中,假如银盐仅仅送人花梗部位,则可能产生半红半绿的果实。阻止番茄果实红熟的物质是如何改变番茄正常代谢的,目前正着手分析,以确定成熟期中正常发生的什么样的变化受到抑制,正如测定阻止番茄红熟所需要的银的浓度,乙烯、酒精不溶固体,葡萄糖和果糖含量一样,也要测定番茄果壁红、绿两部分的滴定酸和总酸度, Incorporation of silver in the form of small amounts of thiosulfate into evaporative gas streams that prevent ripening of green tomato fruits may produce half-red and greenish fruits if the silver salt is fed to the pedicel site only. Preventing tomato ripe fruit from altering the normal metabolism of tomatoes is currently under analysis to determine which changes normally occur during maturity are inhibited, just as the concentration of silver needed to prevent tomato ripening, ethylene, alcohol Insoluble solids, glucose and fructose content, but also to determine the tomato fruit wall red and green two parts of the titration acid and total acidity,
