The fifty or so climatic plant growth and testing units in the phytotron opened in the Agricultural Research Institute of the Hungarian Academy of Sciences in 1972 provided the technical conditions required for exact plant research in Martonvásár. In the high quality phytotron units, manufactured by the Canadian company Controlled Environments Ltd. (Conviron) the climate of any part of the world where vegetation exists can be simulated in reproducible programmes, with temperatures ranging from -25°C to +45°C. The climatic programmes employed in the phytotron units are fundamentally determined by the research aims and strategy. However, when elaborating climatic programmes the technical parameters of the phytotron units must also be taken into consideration. In general the programmes simulate natural weather conditions, though special simplified programmes which do not reflect nature also exist. During the 25 years since the Martonvásár phytotron went into operation a large number of climatic programmes have been elaborated and utilised.The data presented here include the T1, T3 and t2 programmes, which simulate spring weather, and the Ny3 programme used to create summer conditions. Programmes M29, FDA and PDAS are based on autumn weather data and are used when testing the frost resistance of cereals. Special programmes have been elaborated for the raising of maize plants (Szk and Tk).
