摘要:

浙江省叶用芥菜种类丰富、风味独特、抗逆性强,是耐热速生叶菜开发利用的优异资源。为探究夏季高温对芥菜生长和品质的影响,以20份芥菜种质为材料,从外观、营养、口感3方面比较分析不同季节种植的芥菜种质。结果发现,与秋冬季芥菜相比,夏季芥菜出现叶色褪紫、叶柄伸长、叶面积变小的现象。夏季芥菜的营养品质表现优异,芥子油苷、可溶性糖和抗坏血酸含量显著高于秋冬季芥菜。大多数夏季芥菜种质存在苦味,但苦味与芥子油苷等品质性状间不存在相关性。综上所述,尽管夏季芥菜营养品质表现优异,但叶面积变小、有苦味的性状仍需进一步优化,以提升其综合价值。

Abstract:

The leaf mustard(Brassica juncea) in Zhejiang Province is characterized by its rich variety, unique flavor, and strong stress resistance, making it an excellent resource for the development and utilization of heat-tolerant and fast-growing leafy vegetables. To explore the impact of high temperature in summer on the growth and quality of leaf mustard, 20 germplasms of leaf mustard were used as materials to comparatively analyze the leaf mustard planted in different seasons from three aspects: appearance, nutrition and taste. The results showed that, compared with leaf mustard in fall-winter,leaf mustard in summer exhibited phenomena such as leaf color fading from purple, petiole elongation, and reduced leaf area. The nutritional quality of leaf mustard in summer was excellent, with contents of glucosinolates, soluble sugar, and ascorbic acid significantly higher than those in fall-winter. Most leaf mustard germplasms in summer had a bitter taste, and no correlation was found between bitterness and quality traits including glucosinolates. In summary, although the nutritional quality of leaf mustard is excellent, the reduced leaf area and bitter taste still need further optimization to enhance their overall value.

Key words: leaf mustard, summer, fall-winter, appearance quality, nutritional quality, bitter taste
