Study of the influence of the basic spectra of discrete light sources on the seeds of greenhouse cultures

Abstract

© Published under licence by IOP Publishing Ltd. This article refers to studies conducted on the seeds of vegetable and green crops with low useful mass, which require light stimulation at all periods of development. Research was conducted using RGBW LEDs. There is a large number of scientific studies proving the effectiveness of the technology of photostimulation of seeds and seedlings of various crops. However, there is no consensus on what the positive effect of the variable light field on a biological object is based. This is due to the complexity of the process of photosynthesis, where the productivity of photosynthesis is considered as an integral response to the influence of external conditions. The study of the influence of various light modes on plants is necessary to search for performance criteria. The found efficiency criteria will provide an opportunity to systematize the many well-known results of the impact of variable light conditions on plants in order to identify plants as a biological object by optical properties, as well as to use to standardize technological lighting in greenhouse production.
