In two-year trials taking place at the Faculty of Horticulture in Lednice (Mendel University of Agriculture and Forestry in Brno), three cultivars of sweet fennel (Foeniculum vulgare Mill. ssp.vulgare var. azoricum [Mill.] Thell) - Precoce di Bologna, Rudy F1 and Zefa Fino have been evaluated. The trials were conducted in two terms in each of the trial years (summer and autumn term). In the harvest time, nutritional value was evaluated: content of vitamin C, minerals (K, Na, Ca, Mg), dietary fibre, dry matter and nitrates. Besides, the weights of pseudobulbs and its yield have been evaluated. The content of the monitored substances...

The performance of the apple (Malus domestica Borkh) cultivar Imperial Double Red Delicious (Imperial D.R.D.) grafted on the following 5 rootstocks: (I) seedling, (ii) M 7, (ii) MM 104, (ivv) MM 109 was investigated. The highest yield per tree was recorded for trees on seedling rootstock, while the lowest for the cultivar grafted on M 7. Production efficiency of Imperial D.R.D. was higher when grafted on MM 106 and M 7, intermediate on seedling and MM 104, and the lowest on MM 109. The highest leaf photosynthetic rate (Pn) was measured for scions grafted on seedling although it was not significantly different...

Determination of the most optimal types and concentrations of plant growth regulators as medium constituents is one of the most important aspects of successful micropropagation, among other in vitro factors. With the aim of optimization of in vitro multiplication of sweet cherry cv. Lapins the effect of following cytokinins has been studied: benzyladenine (BA), isopentenyl adenine (2iP), kinetin (KIN) and thidiazuron (TDZ) at concentrations of 1, 2, 5, 10 and 15μM, combined with auxine, indole-3-butyric acid (IBA) at concentrations of 0, 0.5, 2.5 and 5μM. MURASHIGE and SKOOG (1962) was the basic medium used in all the combinations....

An in vitro propagation of an economic leguminous tree, Acacia chundra, has been standardized. Induction of bud sprout was obtained from shoot tip and nodal explants derived from in vitro grown plants of A. chundra on the Murashige and Skoog (MS) basal medium supplemented with 6-benzylaminopurine (BA) (1.0 mg/l) and 20 mg/l adenine sulfate (Ads). The rate of multiplication was obtained on MS medium supplemented with 1.5 mg/l BA, 0.01 to 0.05 mg/l (indole-3-acetic acid) IAA and 50 mg/l Ads. The multiplication rate varied from 3 to 6 shoots depending on the growth regulators used. Excised shoots were rooted on half-strength...

Hort. Sci. (Prague), 2008, 35(1):27-34 | DOI: 10.17221/650-HORTSCI
An efficient protocol was developed for micropropagation of hybrid roses by manipulating growth regulators, photoperiods, gelling agent and subculture period. Multiple shoots were achieved from nodal explants of Rosa hybrida cvs. Cri Cri, Pariser Charme and First Red on the Murashige and Skoog (MS) medium supplemented with 1.5-2.0 mg/l BA (6- benzylaminopurine), 50 mg/l Ads (adenine sulfate) with 3% (w/v) sucrose. Inclusion of indole-3-acetic acid (IAA; 0.1-0.25 mg/l) into the cytokinin-rich medium promoted high frequency of shoot multiplication. The induction of multiple shoots was also affected by photoperiod and subculture period. Higher...
In vitro propagation of Gerbera: A Review

Hort. Sci. (Prague), 2008, 35(1):35-44 | DOI: 10.17221/651-HORTSCI
Gerbera has gained popularity in the past few years in many countries of the world and it is in great demand in the floral industry as cut flower as well as potted plant due to its beauty, colour, long vase life, and ability to rehydrate after long transportation. The most commercial cultivars are propagated through vegetative means by multiplication through divisions of clumps; however, the multiplication by this method is too slow to be commercially viable. To commercialize this crop and to meet the growing demand for planting material, tissue and organ culture techniques are being used as alternative methods for propagation in many countries....
