	abstract = {The growth and morphogenesis of spearmint (Mentha spicata L.), thyme (Thymus vulgaris L.), and water mint (Mentha aquatica L.) were determined after four weeks under various levels of CO2. Those plants grown in a greenhouse in ultra-high CO2 levels (>=3,000 μl CO2/liter) had increased fresh weight, and leaf, root, and shoot numbers as compared with plants grown under the same conditions in ambient air or in high CO2 levels (7,500 μl CO2/liter). For example, fresh weight of spearmint and water mint increased 150 and 220 percent, respectively, under 10,000 μl CO2/liter as compared with growth under 350 μl CO2/liter. Thyme fresh weight increased 160 percent under 3,000 μl CO2/liter as compared with growth under ambient air. Shoot cultures given an elevated CO2 (10,000 μl CO2/liter) pretreatment invariably exhibited higher rates of growth and morphogenesis upon transfer to soil as compared with shoots pretreated with ambient air, regardless if the plant was subsequently grown in ambient or elevated CO2 levels.},

	abstract = {The growth and morphogenetic development in shoot cultures of lemon basil (Ocimum basilicum), oregano (Origanum vulgare), peppermint (Mentha x piperita), spearmint (Mentha spicata), and thyme (Thymus vulgaris) shoots on MS salts and 0.8 percent agar containing 0 or 3 percent sucrose were determined under 350, 1,500, 3,000, 10,000, and 30,000 μl CO2/liter of air were determined after 8 weeks growth. High CO2 levels, especially the ultra-high levels (>= 3,000 μl CO2/liter of air), substantially increased fresh weight and leaf and root numbers in all cultures, whether or not the basal media contained sucrose, as compared with cultures grown on the same basal media under ambient air (350 μl CO2/liter of air). Ultra-high CO2 levels, also, enhanced the formation of aerial adventitious roots from the shoots of all species tested. A photosynthetic photon flux density of 180 μmole. m-2 s-1 using a 16 h light/8 h dark photoperiod consistently provided better growth than lower light levels.},
