以9个不同品种的生菜为试材,在夏季高温环境条件下的生长和品质进行了比较,以筛选适宜在海南夏季栽培的散叶生菜品种。结果表明:从植株的形态指标和商品性综合来看,以“辛普森精英”、“意大利耐抽薹生菜”和“奶油生菜”3个品种表现较好;从品质指标来看,以“奶油生菜”最好,且极显著优于“辛普森精英”和“意大利耐抽薹生菜”。因此,从综合指标来看,“奶油生菜”是适宜在海南地区夏季栽培的生菜品种。
Nine different varieties of lettuce were used as materials to compare the growth and quality under high temperature in summer in order to screen the leafy lettuce varieties suitable for summer cultivation in Hainan. The results showed that the three varieties of “Simpson Elite”, “Italian boll-resistant lettuce” and “creamy lettuce” performed well from the morphological and commercial characteristics of the plants. From the quality index , “Cream lettuce” is the best, and very significantly better than “Simpson elite” and “Italy resistant bolting lettuce”. Therefore, from a comprehensive point of view, “cream lettuce ” is suitable for summer cultivation of lettuce varieties in Hainan.
