Problematika hladnega skladiščenja pri proizvodnji potaknjencev zelnatih in lesnatih okrasnih rastlin

Matej VOŠNJAK, Gregor OSTERC

Povzetek


Razmnoževanje s potaknjenci je najpomembnejša in najpogosteje uporabljena metoda vegetativnega razmnoževanja rastlin v okrasnem vrtnarstvu. V verigi proizvodnje sadik se pridelovalci poslužujejo različnih tehnik in metod, da bi zagotovili oziroma ohranili karseda kakovosten rastlinski material. Zaradi selitve večjih svetovnih pridelovalcev zelnatih okrasnih rastlin v tropska in subtropska območja, kjer je pridelava enostavnejša, cenejša in lažja, je ohranjanje kakovosti materiala v času transporta postalo ključnega pomena za nadaljnjo proizvodnjo rastlin. Metoda hladnega skladiščenja se uporablja pri vegetativnem razmnoževanju in pri transportu potaknjencev zelnatih in lesnatih okrasnih rastlin iz ekvatorialnih delov do območij, kjer jih nato koreninijo. Hladno skladiščenje zniža temperaturo rastlinskega materiala, posledično se upočasni metabolizem rastlin med skladiščenjem, ohrani se rastni potencial in kakovost potaknjencev ter podaljša se njihovo obstojnost. V prispevku je predstavljen pregled na področju hladnega skladiščenja potaknjencev različnih vrst okrasnih rastlin, s poudarkom na potaknjencih zelnatih, lesnatih rastlin in rastlin iz in vitro proizvodnje.
