Abstract:
Taking ‘Jiangshu No.1 towel’(S1),‘Liuyesheng towel’(S2),‘Changsharou towel’(S3),‘Hangzhourou towel’(S4),‘Zhusigua No.1’(S5) 5 excellent breeds of towel as materials,the photosynthetic ability,yield and nutritional quality of different towel breeds were determined,in order to select excellent towel species that were suitable to grow in northern greenhouse in winter and spring.The results showed that the comparative result of average value of different leaf position leaves’ net photosynthetic rate was:S5＞S1＞S4＞S3＞S2,the abilities of S1 and S5 in using weak light were the strongest because the apparent quantum efficiency of S1 and S5 were significantly higher than other towel grourd breeds;The average single yield of S5 was the highest and was 6.96 kg,then S1,the average single yield was 6.36 kg,the comparative result of other three towel gourd breeds was:S4＞S3＞S2;the fruits quality of S1,S3 and S5 were better than that of S2 and S4 because the contents of the soluble sugar,the soluble protein and vitamin C of S1,S3 and S5 were higher and the contents of nitrate who was harmful to health were lower than that of S2 and S4.
