Abstract

A method of determination of total daily irradiance of plants by luminescent radiation of fluorescent films in conditions of protected soil was offered. It was shown that the total energy exposure for films with a typical content of luminophor was from 0.05 J/cm2 for films with inorganic luminophor to 0.134 J/cm2 for films with organic luminophor in May 2003–2005. The results of investigation allowed us to obtain data on the value of plants irradiance by luminescent radiation required for effective influence on the plants growth and development.
