The maximum activity of catalase (17,3-97,8 ml O2/min) was found in monocot species of flowering plants: Chlorophytum, Elettaria and Cyperus. In species of Plectranthus and belonging to Class dicot catalase activity (5,8-7,8 ml O2/min) below than 2,2-16,9 times monocot species. The light level at which plants can grow and develop long-term the greatest aboveground mass, have a high activity of catalase and the maximum phytoncidic activity depends on the requirements for this type of environmental factor. Plectranthus purpuratus Harv. and Elettaria cardamomum (L.) Maton are the most potent activity of catalase and phytoncidic have maximum activity at a higher light level - 2000 lux. When the illuminance of these parameters decrease in both species and fitontside activity falls to a great extent (30-33 %), in contrast to the reduction in catalase activity (4-12 %). And at this shade-tolerant Elettaria catalase activity in the 7.7-7.9 times higher in all cases than the light-demanding Plectranthus.
