Original Abstract

The temperature of plants is a necessary factor for the physiological processes and is the result of the actual heat balance of vegetation. If the temperature of the plant falls below the temperature of the dew point (air), it begins to condense dew. The dew point is the temperature to which moist air must be cooled at constant barometric pressure, so the water vapor condensed from it. From the known temperature and relative humidity, dew point can be calculated using the Magnus formula. If the plant is inserted into the translucent plastic box, then there is no air circulation inside the bowl affected by external environment. This article deals with the early stages of pine embryos grown in Petri dishes, when the temperature change, condensation is evident. Effect of magnetic field on tissue culture is shifting the dew point temperature and under normal temperature there is no condensation. The aim of this project is to determine how much is shifted the dew point of tissue cultures grown in Petri dishes between the permanent magnets embedded on a defined magnetic field gradient. To determine the change in dew point temperature, the samples were divided into two groups. The first group was placed between the permanent magnets and the second group (control) was placed outside the scope of magnets. The measurement was carried out in a Peltier device, where the ambient temperature gradually decreased to low levels and then increased to determine the dew point of the dish. The device was placed in a room where constant terms are provided to eliminate errors caused by the external environment.
