The aboveground parts of radish (Raphanus sativus L.) are typically discarded after harvesting the roots. However, numerous bioactive compounds have been identified in radish leaves, and dried leaf products have garnered attention as a health food owing to their high fiber content. Here, we assessed the morphological and physiological characteristics of the leaves of 14 commercial radish cultivars and the effects of postharvest drying treatment on their glucosinolate (GSL) contents. The morphological and physiological characteristics of radish leaves exhibited considerable variation, depending on the cultivar. ‘Baekbong’ and ‘Baekja’ presented higher values for the assessed morphological and physiological characteristics than other cultivars. ‘Baekja’ had the best growth parameters, including leaf length and fresh and dry weights, among the tested cultivars. The total and individual GSL content was the highest in the cultivars ‘Sincheongilpum’ and ‘Taebaek’ at harvest. However, after 10 d of postharvest drying in a greenhouse at ambient temperature, the GSL content was the highest in the cultivars ‘Cheongbok plus’ and ‘Taebaek’. The results of the multivariate data analyses indicated that ‘Taebaek’ is a highly distinctive cultivar in terms of shoot physiology, morphology, and GSL content. The GSL content and profiles were differentially affected by both radish cultivar and postharvest drying treatment.

萝卜的地上部分（Raphanus sativusL.）通常在收获根后丢弃。但是，在萝卜叶中已经发现了许多生物活性化合物，而干叶产品因其纤维含量高而引起了人们的注意，成为健康食品。在这里，我们评估了14个商业萝卜品种叶片的形态和生理特性，以及收获后干燥处理对其芥子油苷（GSL）含量的影响。萝卜叶片的形态和生理特性表现出很大的差异，具体取决于品种。与其他品种相比，“白凤”和“白ja”对形态和生理特性的评估值更高。在测试的品种中，“白ek”具有最佳的生长参数，包括叶长，鲜重和干重。在收获时，新品种“ Sincheongilpum”和“ Taebaek”中GSL的总含量和个体含量最高。然而，在温室中于环境温度下收获后干燥10天后，'Cheongbok plus'和'Taebaek'品种的GSL含量最高。多元数据分析的结果表明，就芽生理，形态和GSL含量而言，'Taebaek'是一个非常独特的品种。萝卜品种和收获后干燥处理均对GSL含量和曲线有不同的影响。多元数据分析的结果表明，就芽生理，形态和GSL含量而言，'Taebaek'是一个非常独特的品种。萝卜品种和收获后干燥处理均对GSL含量和曲线有不同的影响。多元数据分析的结果表明，就芽生理，形态和GSL含量而言，'Taebaek'是一个非常独特的品种。萝卜品种和收获后干燥处理均对GSL含量和曲线有不同的影响。
