Use Sodium Lamps with Different Amalgams in Discharge Tubes for Growing Tomatoes in Closed Ground

Abstract

The features of usage of miscellaneous phylum’s of sources of artificial lighting for lightculture of plants are reviewed. The results of experiments of a radiation effect of sodium lamps high-pressure with the additives of caesium under comparison with other light sources are introduced. The differences in tomato plants reaction varieties De Barao and Hybrid of Tarasenko and on accumulation of pigment and their relation set are established
