以3个桃品种（Prunus persica（L.）品种：融化品种‘Hakuho’，不融化品种‘Early Cold’和石质硬品种‘Yumyeong’。融化和nonmelting品种表现出增加乙烯生产和下降的果肉硬度，虽然他们的程度不同，而石硬品种产生很少或根本没有乙烯，并保持坚定的存储过程中。因此，后者显然具有不同于前两个品种的成熟特性。石硬桃是一个乙烯产生突变体，可作为改善甜桃贮藏品质的遗传资源。
We examined changes in ethylene production and flesh firmness after the harvest of three peach [Prunus persica (L.) Batsch] cultivars: a melting cultivar 'Hakuho', a nonmelting cultivar 'Early Cold' and a stony hard cultivar 'Yumyeong'. The melting and nonmelting cultivars showed increases in ethylene production and drops in flesh firmness, although their degrees differed, whereas the stony hard cultivar produced little or no ethylene and remained firm during storage. Hence, the latter apparently has different ripening characteristics from the former two cultivars. Stony hard is a mutant in ethylene production and, thus, may be used as a genetic source for improving keeping quality of dessert peaches.
