摘　　要：采用适宜的补光调控策略对于温室培育高产优质的罗勒(Ocimun basilicum)植株至关重要。试验在补充相同日累积光照量的条件下,使用白色(W)、蓝色(B)和红蓝(RB)LED对温室罗勒进行补光,以未补光为对照(CK),探究不同光质对罗勒植株生长和品质的影响并进行综合评价。结果表明,与CK相比,RB处理中罗勒叶片的总叶绿素含量、地上部干质量和地上部鲜质量分别提高了45.1%、274.3%和232.7%,罗勒叶片的可溶性糖含量和维生素C含量分别提高了357.1%和52.9%;B处理中罗勒叶片的叶绿素a含量和维生素C含量分别提高了51.2%和76.5%。采用主成分分析及综合评价,得出RB处理的罗勒植株综合得分最高,排名第1。综上,补光处理的罗勒植株在生长和品质方面均优于未补光处理,且补充红蓝LED光源有利于罗勒植株的生长,确定红蓝LED光源为秋冬和早春等弱光季节温室内罗勒栽培的适宜补光策略。It is important to adopt appropriate regulation strategies of supplementary light for the cultivation of high-yield and high-quality basil(Ocimun basilicum) plants in greenhouse.In this experiment,white(W),blue(B),and red plus blue(RB)LED were used as supplementary light for basil in greenhouse with same daily light integral,and the basil grown without supplementary light was used as the control(CK) to explore the influences of different light qualities on the growth and quality of basil plants and conduct comprehensive evaluation.The results showed that the total chlorophyll content and shoot dry and fresh weight of basil plants in treatment RB were increased by 45.1%,274.3%,and 232.7% compared with CK,respectively,and the soluble sugar content and vitamin C content of basil leaves were increased by 357.1% and 52.9%,respectively.Compared with CK,chlorophyll a content and vitamin C content of basil leaves in treatment B were increased by 51.2% and 76.5%,respectively.In addition,the methods of principal component analysis and comprehensive evaluation showed that the comprehensive scores of basil plants treated by RB were the highest and ranked the first.In summary,the growth and quality of basil plants treated with supplementary light were superior to those treated without supplementary light,and the addition of red plus blue LED was beneficial to the growth of basil plants.Therefore,the red plus blue LED light source was a suitable supplementary strategy for basil cultivation in greenhouse during the weak light seasons such as autumn,winter,and early spring.
