ON BIOLOGY OF A RARE SPECIES Iris humilis Georgi IN BASHKORTOSTAN
Abstract
The article presents the research results of phenological observations and morphometric indicators of a rare species Iris humilis Georgi in the Bashkortostan Republic in the nature and under the introduction. I. humilis is included in the Red List of the Bashkortostan Republic and has the category and the status of rarity 1 meaning the species on the brink of extinction. I. humilis is widespread in the Bashkir Trans-Urals and can be met in rocky steppes of Stipetum rubentis association of Festuco-Brometea class steppe vegetation. Considering the rhythm of blossoming the iris is a spring plant. Its blossoming begins in the second decade of May and lasts only 8 days. The longest is the fruiting stage (21—26 days). The terms of certain phenophases depend on the weather conditions of the vegetation year. The tamed plants of I. humilis are mainly of morphometric parameters, thus surpassing the natural ones. Considerably high parametrical variation of I. humilis in nature is observed for a number of shovels (СV — 78,1%), generative shoots (СV — 44,95%), normal (СV — 3,6—21,9%) — for the majority of parameters. The normal variation of parameters (СV — 11,4—30,2%) is observed under the introduction.
