不同品种莴笋的品质比较研究

Comparative Studies on Quality of Different Lettuce Cultivars

通过盆栽试验对5个品种莴笋的生物学特性、生理和营养特性及产量、品质进行了比较研究。结果表明:"大白甲"株高最低,"挂丝红"叶片数最多,"润农"最大叶面积最大;"挂丝红"和"大白甲"的叶绿素含量较高,"挂丝红"叶片的养分含量较高。5个品种莴笋的产量以"挂丝红">"尖叶">"大白甲">"润农">"双尖",硝酸盐含量以"润农">"尖叶">"双尖">"大白甲">"挂丝红",营养品质指标(Vc、可溶性糖、氨基酸)以"挂丝红"、"双尖"较好。综合产量和品质,"挂丝红"为高产优质的最佳品种。

A pot experiment was carried out to comparative study the biological characteristics,physiological and nutritional properties and yield and quality of five lettuce cultivars.The results indicated that the maximum height was observed in ＂Dabaijia＂,the most amount of leaf was in ＂Guasihong＂,the largest area of leaf was in＂ Runnong＂,the higher concentration of chlorophyll was in ＂Guasihong ＂and ＂Dabaijia＂,and the higher concentration of nutrient elements was also in ＂Guasihong＂.The yield of five lettuce cultivars were in the order of＂Guasihong＂＂Jianye＂＂Dabaijia＂＂Runnong＂＂Shuangjian＂,the concentration of nitrate were ＂Runnong＂ ＂Jianye＂ ＂Shuangjian＂ ＂Dabaijia＂ ＂Guasihong＂.The nutritional quality（Vc,soluble sugar,amino acid） of ＂Guasihong＂and ＂Shuangjian＂ were better among five lettuce cultivars.Taking yield and quality into consideration,the optimum lettuce cultivar was ＂Guasihong＂ for higher yield and better quality.
