INFLUENCE OF SOURCE PROPAGULE ON RHIZOME PRODUCTION FROM LINGONBERRY CUTTINGS |

| Abstract:
Increased branching and vigorous vegetative growth is often noted in plants produced through micropropagation. Previous reports on lingonberry, Vaccinium vitisidaea L., reported that micropropagated plants produced abundant rhizomes in contrast to conventional cuttings which rarely produced rhizomes. Our study compared conventional softwood cuttings from mature plants originally derived from division, conventional softwood cuttings from mature plants originally derived from tissue culture, and microshoot cuttings directly from in vitro cultures. ‘Koralle’, ‘Erntedank’ and ‘Sussi’ were used. The number of branch shoots from the main stem and the number of rhizome-produced shoots were counted 5 and 7 months after initiating cuttings. Within 5 months, softwood cuttings taken from both division-derived and tissue culture-derived stock plants produced plants with as many rhizomes and branch shoots as plants grown from microshoots. | |
