Application of a new growth regulator for micropropagation of some species of the genus Crataegus
The paper presents the results of application of a new growth regulator for micropropagation of some species of the genus Crataegus. In the study we developed methods for microclonal propagation of Crataegus arnoldiana, C. dahurica, C. sanguinea, C. submollis, based on regeneration of plants from ap...
