摘要：[Objectives]The study aims to provide important reference for the breeding and research of new varieties of functional broad-shoulder bitter gourd.[Methods]8 pure varieties of local broad-shoulder bitter gourd landraces in Foshan were used as experimental materials,in which polysaccharide,cellulose and vitamin C content were measured.[Results]Among the 8 varieties of local self-selected broad-shoulder bitter gourd in Foshan,the polysaccharide content of Foxuan 6 was the highest,up to 113.78 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The polysaccharide content of Foxuan 2 was the lowest.The cellulose content of Foxuan 8 was the highest,reaching 24.50 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The cellulose content of Foxuan 4 was the lowest.The vitamin C content of Foxuan 5 was the highest,reaching 74.24 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The vitamin C content of Foxuan 4 was the lowest,only 7.05 mg/100 (g·FW).In a word,there were big differences between the 8 varieties of broad-shoulder bitter gourd in terms of polysaccharide,cellulose and vitamin C content.[Conclusions]It is possible to make full use of their own quality differences and develop new varieties of functional broad-shoulder bitter gourd by means of cross combination.
