Abstract
In this research the thermal evolution in maize seeds Zea mays L was studied when lowintensity laser irradiation was applied during 60 s The seeds were irradiated in three different conditions suspended in air placed on an aluminum surface and finally placed on a cardboard the evolution of the seed temperature was measured by an infrared camera Photoacoustic spectroscopy and the Rosencwaig and Gersho model were used to determine the optical absorption coefficient beta of the seeds The results indicate that using 650 nm laser light and 274 mW it is possible to produce temperature changes up to 906~circ hbox C after 1 min on the seeds Comparing the mean temperature of the seeds during and after the incidence of light from a laser it was found that there were statistically significant differences Ple 005 from time t 1 to time t 16 t 1 to t 16 and t 3 to t 16 for the laser turned on and off respectively The seed condition that had the highest temperature variation relative to the initial temperature during the irradiation laser exposure involved the seeds suspended in air With regard to the stage of decay of the temperature it was found that the seed condition that decays more slowly was the seed placed on the cardboard It was also found that blackdyed maize seeds are optically opaque in the 300 nm to 700 nm range Also the thermal diffusion length is smaller than the optical penetration length In the present investigation it was shown that there is a thermal component associated with the mechanisms of laser biostimulation which is also a function of the container materials of the seed In this way the effects of laser treatment on maize seeds involve at least a temperature effect It is important to know the temperature changes in the seeds that have been irradiated with a laser beam since they could have substantial practical and theoretical importance
