Abstract
The effect of white fluorescent, blue, red, and blue plus red mixture light at a 90 10 mol m s light intensity on growth, net photosynthetic rate (NPR), and ethylene production in Ageratum houstonianum 'Blue Field', Tagetes erecta 'Orange Boy', and Salvia splendens 'Red Vista' plug seedlings was investigated for 14 days. Higher leaf area and NPR of ageratum seedlings were achieved by mixture radiation of blue and red as compared to monochromic blue or red, whereas ethylene production was not affected by different light qualities. Ageratum and salvia seedlings under blue or red light showed the greatest plant height. Photosynthesis of marigold and salvia seedlings was stimulated by all light qualities except for monochromic blue light. Red or mixture light quality was the most effective in the promotion of ethylene production of marigold and salvia, and inhibitory response was shown under blue light. It was found that growth, photosynthesis, and ethylene production in ageratum, marigold, and salvia plug seedlings depended upon different light qualities for the experimental period.
