The monograph examines the theoretical issues of the selection of hemp associated with the functioning of two types of trichomes - glandular and cystolite, which play an important role in the viability of plants.
The main purpose of glandular hairs is to protect plants from pests and diseases. They contain cannabinoids, which contain narcotic substances. The morphological structure of glandular hairs, regularities of their localization on vegetative and generative organs, features of synthesis and inheritance of cannabinoids are presented. The results of biological research of glands allowed to develop theoretical bases and methodical methods of selection of varieties for reducing the content of cannabinoids in plants and to obtain non-narcotic varieties as a significant contribution to the overall fight against drug addiction. The comparative study of narcotic and non-narcotic varieties, which shows certain changes in the functioning of the ferruginous hairs, features inheritance of the sign of non-narcotic. It is indicated on methods of fixing this feature in offspring.
Compared with the glandular hairs, hemolysts of cystolite hairs are still poorly investigated. Therefore, the information shown in the monograph is of great importance. Cystolite hairs have a protective and physiological role aimed at protecting plants against adverse growing conditions, regulating the temperature and water regime of plants. Morphological peculiarities of the structure and density of placement of trichomes on different organs of plants were revealed. It was found that the largest number of cystolytic hairs is found on the lower surface of the leaves. According to this sign there are significant inter-grade differences. This makes it possible to select plants to increase the degree of pubescence of hemp leaves, which is relevant for varieties grown in arid conditions.
The monograph is intended for biologists, breeders and geneticists who deal with hemp, as well as for a wide range of readers interested in raising scientific and cognitive knowledge.
