Abstract:	Ozone depletion is primarily due to chlorophores compounds released into the atmosphere due to anthropogenic activities in the latter part of the 20th century (Kerr, JB, 1993, Butler et al., 1999), and the effect of this phenomenon is very high, regarding life on Earth but also the socio-economic implications. Climate changes predicted for the future, although uncertain, are inevitable because of continue anthropogenic activities. A chronic exposure to ozone of plants for longer period of time, may cause a decrease in growth, harvest, an inhibition of photosynthesis, premature aging of leaves, a poor distribution of biomass, a damage of propagation processes etc. (Black et al., 2000, Saitanis and Karandinos, 2002 Sanderman, 1996). In the experiment we conducted in the laboratory we determined the effects of ozone together with ultraviolet radiation UV-B radiation, into a special gas room where ozone dosing was done gradually over a period of 4-10 days, following especially the number and size of the maize plants leaves, for the Helga hybrid.
