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.. In ornamental horticulture, propagation by cuttings is the most important and most commonly used method of vegetative propagation of plants. During propagation, growers use various techniques to ensure or maintain the highest quality of material. With the relocation of the world’s major ornamental plant growers to tropical and subtropical areas, maintaining the quality of the material during transport has become crucial for further plant production. The method of cold storage of plant material is used in vegetative propagation and in the transport of cuttings of herbaceous and woody ornamental plants from equatorial areas to the areas where they are to be rooted. Cold storage lowers the temperature of the plant material, thus slowing down the metabolism of the plants during storage, preserving the growth potential and quality of the cuttings and extending their shelf life. This paper reviews the management of cuttings of various ornamental plant species by cold storage, focusing on cuttings of herbaceous plants, cuttings of woody plants, and in vitro production. |
