Conservation of plants was carried out by the method of Strasburger-Flemming
(Prozina, 1960). Preservative fluid is a mixture of
alcohol-glycerol-water in a ratio of 1:1:1. Fixation was performed in
96% ethyl alcohol. Tubers and vegetative parts of the studied plants
were recorded. Anatomical specimens were prepa-red with a microtome
having a freezing unit TOC-2. Sections were placed in glycerine
and balsam in accordance with conventional techniques of
Prozina (1960), Permyakova (1988) and Barykina (2004). The thickness
of the anatomical sections was 10 to 15 microns. For a
quantitative analysis, morphometric parameters were measured using
ocular micrometer MOV-1-15 (with lens x 9 and increase x 10.7).
Micrographs of anatomic sections were made on a micro-scope
with a camera MC 300 CAM V400/1.3M.
