Description
| - The experiment with propagation of blueberry cultivars by softwood cuttings was carried out at RBIP Holovousy during the years 2004-2005. Rootability was tested with following cultivars: Berkeley, Bluecrop, Bluegold, Bluehaven, Bluejay, Blueray, Bluetta, Brigitta, Burlington, Collins, Croatan, Darrow, Earliblue, Elliott, Gila, Iranka, Jersey, Nelson, Northland, Patriot, Rancocas, Spartan, Sunrise and Toro. Cuttings prepared in the middle of July 2004 were planted on the propagation bed with intermittent mist in greenhouse. In the spring of following year the rooted cuttings were containerised and then grown in open air under irrigation. In autumn the number of grown plants was recorded. The best results concerning rootability of softwood cuttings and survival of potted plants proved cultivars Croatan, Jersey, Bluecrop, Nelson and Northland. Propagation methods using shoot tips in vitro culture were optimized for cultivars ´Blueray´, ´Nelson´ and ´Bluecrop´. Sterilization treatment times, MS ba

- Pokus s rozmnožováním odrůd kanadské borůvky zelenými řízky byl prováděn ve VŠÚO Holovousy v období 2004-2005. Zakořeňovací schopnost byla testována u odrůd: Berkeley, Bluecrop, Bluegold, Bluehaven, Bluejay, Blueray, Bluetta, Brigitta, Burlington, Collins, Croatan, Darrow, Earliblue, Elliott, Gila, Iranka, Jersey, Nelson, Northland, Patriot, Rancocas, Spartan, Sunrise a Toro. Řízky byly připravovány v polovině července 2004 a vysazovány do množárny se systémem zamlžování. V následujícím roce byly přesazeny do kontejnerů a umístěny do venkovních prostorů pod závlahu. Na podzim byl zaznamenán újem rostlin.Nejlepší zakořeňovací schopnost zelených řízků a újem rostlin v kontejnerech vykazovaly odrůdy Croatan, Jersey, Bluecrop, Nelson a Northland. Pro odrůdy Blueray, Nelson and Bluecrop byla optimalizována metoda množení vrcholovými kulturami. Byla testována doba sterilizace, média založená na MS, koncentrace růstového regulátoru TDZ.Kontaminace explantátů byla úspěšně odstraněna sterilizací v 0.15 (cs)
