Abstract english

It is demonstrated that photographic images of plants can be produced in the absence of external illumination using an image intensifier. The image is produced by the weak delayed light emission (afterglow) from photosynthetically active chloroplasts. The use of such phytoluminographs is proposed for the study and diagnosis at an early stage of disturbances due to parasites, mineral deficiency, herbicides, frost, etc.
