White Purple broom (Chamaecytisus purpureus Scop.) / Rdeči reličnik (Chamaecytisus purpureus Scop.)

Abstract

White-flowered representatives are just an aspect of the diversity of the Slovenian flora. Their frequency varies, differing also with respect to single parts of Slovenia. Purple broom (Chamaecytisus purpureus Scop.) is a plant of dry grasslands in Scots pine forests, from lowlands to the montane zone. It was discovered by Wulfen in the vicinity of Solkan and described by Scopoli. On the dry meadow near Ljubljana on the year 2013 apeared with usual coloration for that species also an islet of totaly white plants. It seems this occurrence could be a consequence of stress, i.e. drought, which triggered the expression of recessive genes which are white homozygous varieties of purple broom. 

Key words: dry meadow, purple broom (Chamaecytisus purpureus), drought, white colour

Belo cvetoči predstavniki so le en vidik raznolikosti slovenske flore. Njihova pogostost se spreminja in se razlikujejo glede na posamezne dele Slovenije. Rdeči reličnik (Chamaecytisus purpureus Scop.) je rastlina suhih travnikov in gozdov rdečega bora, od nižine do montanskega pasu. Odkril ga je Wulfen v bližini Solkana, opisal pa Scopoli. Na suhem travniku v bližini Ljubljane se je v letu 2013 pojavilo poleg rastlin z normalno obarvanostjo še nekaj skupin popolnoma belo cvetočih rastlin. Zdi se, da je ta pojav lahko posledica stresa, to je suše, ki je sprožila izražanje recesivnih genov, kot so bele homozigotne različice rdečega reličnika.
