摘要:
为促进紫外线在植物工厂生产中的应用，在人工光源的水培试验室中，以红边生菜和紫叶生菜为材料，在红蓝组合LED光源中加入不同强度的UV-A，测定生菜的生长量及品质。结果表明：与红蓝组合光质相比，添加UV-A后，两种生菜的株高降低，随着辐射强度的增加逐渐下降。两种生菜地上鲜重经UV-A照射后均比对照下降，红边生菜未表现出显著差异，紫叶生菜在UV-A强度为50 μmol?m-2?s-1地上鲜重比对照显著降低。两种生菜的地下鲜重和地下干重随UV-A辐射强度逐渐增加，对叶片数无显著影响。添加UV-A增加了两种生菜的可溶性蛋白质含量，维生素含量随UV-A强度的增加而逐渐提高。两种生菜花青素含量经UV-A辐射处理后比对照均提高，红边生菜在UV-A强度为30 μmol?m-2?s-1时花青素显著提高，紫叶生菜在UV-A强度为30 μmol?m-2?s-1，50 μmol?m-2?s-1时花青素显著提高。
