适于盆栽莴苣品种的筛选

Screening of Suitable Lettuce Varieties for Pot Culture

以引进的7个散叶莴苣品种为试材,种植在根域体积为445cm3的栽培容器内,比较了7个莴苣品种的形态指标、叶色和维生素C含量,以期筛选出适合盆栽的莴苣品种。结果表明:绿色叶片莴苣品种‘Tarifa’和紫色叶片莴苣品种‘Mohican’的生长势强,株幅和叶长较大;‘Tarifa’叶片的维生素C含量为185.3mg/100g,比含量最低的莴苣品种‘Cervantus’高15.5%,‘Mohican’的花青素含量最高,因此绿色叶片散叶莴苣品种‘Tarifa’和紫色叶片散叶莴苣品种‘Mohican’最适宜盆栽。

Taking seven new introduced varieties of lettuce as materials, which were cultivated in pots with 445 cm3 substrate, the morphological index,leaf color, VC content were measured,in order to screen the lettuce variety, which was suitable for pot culture. The results showed that the green leaves lettuce ＇Tarifa and the purple leaves lettuce ＇Mohican had the strong growth,which had advantage in plant width and leaf length. The VC content of ＇Tarifa ＇ was 185. 3 mg/ 100g,15. 5% higher than ＇Cervantus＇ which was the least in green leaves lettuce. ＇Mohican＇ had the highest proanthocyanidins content. So the green leaves lettuce ＇Tarifa ＇and the purple leaves lettuce ＇Mohican were the optimum for pot culture.
