Abstract

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
