Интродукционные возможности представителей рода Astilbe в условиях юга Приморского края

Abstract

The collection of the genus Astilbe of the BGI FEB RAS is represented by 3 species and 136 varieties from 9 garden groups. Under monsoon climate conditions, varieties and species go through all phenological phases successfully. The flowering lasts from late June until mid-September. The pollen viability of varieties and species varies from 0 to 69%. It was found that the viability of A. chinensis pollen is affected by temperature and storage duration. The ability for vegetative propagation of 71 varieties and 2 species was studied. Under the conditions of the BGI FEB RAS, the coefficient of vegetative propagation was 11.3. Recommendations for Astilbe varieties affected by diseases and pests are given.
