摘要：

结球莴苣在高温环境下栽培，植株往往遭受伤害或生长不良，为给生产提供优质的结球莴苣品种，本文选取目前栽培中具有代表性的8个结球莴苣品种进行了春夏露地和秋冬日光温室栽培比较试验，并对其苗期性状、商品性状、营养成分、产量及抗性进行观察比较和分析。结果表明：栽培条件不同，结球莴苣的各项生理指标表现出不同程度的差异。幼苗期J42表现最好，J44次之。J42和J44两个品种的叶片性状指标最好，产量最大，且抗病，W64表现为感病，其余品种均为中等抗病品种，无严重感病现象。J42的综合营养品质最好，而8个品种口感和质地相似，都带有苦味，质地脆。总之，‘国王102’（J42）和‘早玉结球生菜’（J44）这两个品种产量高，性状好，品质优良，抗性强，应加以推广。

Abstract:

Head lettuce was suffered harm and growth badly in high temperature environment cultivation. In order to provide high quality head lettuce varieties, eight varieties of head lettuce were compared, which planted in open country in summer and sunlight greenhouse in autumn. The seedling characters, economical characters, nutrients, production, and resistance were observed and studied. The results showed that the physiological indexes of head lettuce had differences in different cultivate environment. J42 was the best in seedling stage, and J44 was second. J42 and J44 were the best in leaf traits, maximum yield and resistance, W64 had no resistance, and the remaining varieties were moderately resistant varieties which had no serious feeling sick phenomenon. J42 had the best comprehensive nutrition quality, and the 8 varieties taste and texture was similar, all with a bitter taste, texture crisp. In a word, ‘King102’ (J42) and ‘Zaoyu heat lettuce’ (J44) had high yield, good traits, excellent quality and strong resistance, so they deserved to be promoted.
