五个丝瓜品种光合能力及产量和营养品质的比较

Comparing on Photosynthetic Abilities,Yield and Nutritional Quality of Five Towel Grourd Breeds

以"江蔬一号丝瓜"(S1)、"六叶生丝瓜"(S2)、"长沙肉丝瓜"(S3)、"杭州肉丝瓜"(S4)、"驻丝瓜1号"(S5)5个优良丝瓜品种为试材,比较测定了不同品种的光合能力、产量和营养品质,以期筛选出适合北方冬春温室生长的优良丝瓜品种。结果表明:5个品种丝瓜不同叶位净光合速率平均值的比较结果为:S5>S1>S4>S3>S2,且S1和S5的表观量子效率无显著差异,但极显著高于其它3个品种,表明其对弱光的利用能力最强;S5的平均单株产量最高,为6.96kg,其次是S1,为6.36kg,其余3种丝瓜的平均单株产量比较结果为:S4>S3>S2;S1、S3和S5的果实可溶性糖、可溶性蛋白和维生素C含量较高,且有害健康的硝酸盐含量较低,果实营养品质优于S2和S4。

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 fruks 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.
