Abstract
Seeds of tomato cv.
UC-82-A and cucumber cv.
Pobeda F1 were irradiated with helium-neon laser during the day and during the night. The investigations were carried out under field conditions.
It was established that in tomatoes, as a result of irradiation during the night, the photosynthetic intensity was increased by 10.7-12.2% in comparison with the irradiation during the day.
The total quantity of dry phytomass per plant was increased too, by 7.6%. In cucumbers the night irradiation increased the photosynthetic intensity by 11.3-11.8% and the total dry phytomass by 5.7%.
