Vegetativno razmnoževanje žlahtnega jagodnjaka (Fragaria x ananassa Duch.)

Šušmelj, Lara (author), Rudolf Pilih, Katarina (mentor)

Jagode lahko razmnožujemo klasično z živicami iz matične rastline ali s tkivnimi kulturami (vršiček, somatska embriogeneza). Najpogosteje se za razmnoževanje matičnih rastlin uporablja tehniko mikropropagacije. Iz mikropropagiranih rastlin z nadaljnjim razmnoževanjem z živicami vzgojimo sadike za rodne nasade. Namen diplomske naloge je bil proučiti različna gojišča in vlogo hormonov za mikropropagacijo jagod. Mikropropagirane rastline dajo več poganjkov na rastlino, postopek pa se uporablja za komercialno razmnoževanje jagod v številnih državah. S tkivno kulturo poleg virusov odstranimo tudi glivične in bakterijske bolezni. Za uspešno vzpostavitev tkivne kulture je najprej potrebno razkuževanje rastlinskega materiala in gojišč. Kemično razkuževanje gojišč z natrijevim hipokloritom je cenovno ugodno in primerljivo z metodo avtoklaviranja. Rastlinski hormoni, njihove koncentracije in medsebojni vpliv le teh pa so ključnega pomena za popoln razvoj rastline.

• Title: Vegetative propagation of strawberry (Fragaria x ananassa Duch.)

Abstract

Strawberries are still classically propagated by nerves from the mother plant or by tissue culture (tip, somatic embryogenesis). The most commonly used technique for mother plant propagation is micropropagation. The objective of this work was to investigate different media and the role of hormones for micropropagation of strawberries. Micropropagated plants produce more shoots per plant, and the protocol is used for commercial strawberry propagation in many countries. Tissue culture remove viruses but also fungal and bacterial diseases. Successful establishemnt of tissue culture first requires sterilisation of the plant material and the culture media. Chemical sterilisation of culture media with sodium hypochlorite is inexpensive and comparable to autoclaving. Plant hormones, their concentrations and their interactions are crucial for the full development of the plant.
