Starks Gold had the highest values in terms of anther number, average number of pollens per anther, number of pollen per flower and the morphological homogeneity. The pollen viability rates showed significant differences according to stain tests. In vitro pollen germination in 0.5% agar + 15% sucrose + 5 ppm boric acid medium increased with increasing incubation period, and the highest germination was obtained after 48 hours for all cultivars. In orchard trials parallel to pollen tube growth experiments in the laboratory, 0900 Ziraat × Starks Gold combination gave the best fruit set results.

Lapins cv. was used as a scion tester for all these rootstocks; five of them were tested also by Regina cv. Among the new rootstocks G 195/5 was evaluated as the most promising for Lapins cv. The highest rate of mortality and symptoms of poor scion compatibility with Lapins cv. were observed on Weiroot 53 and Weiroot 158. The most vigorous of the tested rootstock was G 497/8 followed by Gisela 7 and Gisela 4. Intermediate vigour was recorded on trees on G 154/7, P-HL-A, Gisela 3 and Tabel Edabriz. The least vigorous were G 195/20, Weiroot 158 and Weiroot 53. The highest accumulated yield per hectare of the Lapins cv. (21.2 tons) was harvested from Gisela 7 rootstock. With Lapins cv. higher yield efficiencies were calculated for P-HL-A, G 195/20 and Tabel Edabriz. In the case of the Regina cv. the highest yield efficiency was on Gisela 7. The mean fruit weight of the Lapins cv. had a span from 8.2 g (Weiroot 53) to 9.7 g (G 195/20). With the Lapins cv. less fruit cracking was observed on fruits from Tabel Edabriz and Gisela 7. Significant differences between tested rootstocks were found also at the time of tree flowering and ripening.

There were six different treatments: conventional farmyard manure, Agro (made from poultry bedding and molasses), Dvorecký agroferm (granulated, made from dried, aerobically-fermented farmyard manure), Agormin (an organo-mineral fertilizer), compost manufactured from plant waste material, mineral fertilizer, and an unfertilized control. All the treatments were applied at rates providing approximately the same level of nutrients. After harvest, the levels of the minerals (K, Na, Ca, and Mg), ascorbic acid, nitrates and yield were measured. There were no significant differences between the treatments in levels of K, Na and Ca in case of organic fertilizers (farmyard manure, Agro, Agormin and compost). The unfertilized control had the highest levels of ascorbic acid; it was significantly higher than in case of farmyard manure which, in turn, had significantly higher values than compost. Significant differences between the treatments were found in the levels of nitrates; the lowest in case of Dvorecký agroferm and in the control. The highest marketable yields were recorded with farmyard manure and Dvorecký agroferm, the latter being significantly higher than the control. This study shows that alternative, organic fertilizers (except compost) have similar qualities as farmyard manure.

The first phase was carried out within the GP 1/4419/47 Adaptability of Cultural Vegetation in Consequence of Global Draining and Warming. Roof gardens are a good place for simulating natural phytocenose sites that are able to accumulate rainfall without taking it to drainage. The second phase of research was conducted within a continuation of GP 1/1316/04, verifying xeric plants for conditions of changing climate in a urbanized environment on different construction systems. For a statistical evaluation it was necessary to select taxa in at least three roof gardens. The basic hypothesis was that all plants are conditionally suitable for roof gardens. Another assumption was that the maintenance of all roof gardens is uniform. Results have shown that some plants are more adaptable and drought-tolerant even if the maintenance of roof garden is not appropriate.

Bulbscales isolated from pre-cooled bulbs of hybrids Rosato and Marco Polo were used. The basal portion with plate (5 × 6 mm) of inner bulbscales was cultured on Murashige and Skoog (MS) medium containing 0.5 or 1 mg/dm3 naphthaleneacetic acid (NAA) and/or benzyladenine (BA). The presence of NAA (0.5 mg per dm3) showed higher explant regeneration, producing about three bulblets per explant as compared to control. About four bulblets per explant were produced at both concentrations of BA. The bulblets with significantly higher fresh weight were obtained on medium containing NAA. Approximately a three-fold increase of bulblet fresh weight was observed with all the concentrations of TDZ in both cultivars. The bulblets cultured with nitrogenous compounds after attaining the size of 14-16 cm flowered during the second year of the growing period without any phenotypic variations.

Inclusion of indole-3-acetic acid (IAA) in the culture medium along with BA + Ads promoted a higher rate of shoot multiplication. Maximum mean number of microshoots per explant (6.65) was achieved on the MS medium supplemented with 1.5 mg/l BA, 50 mg/l Ads and 0.1 mg/l IAA after 4 weeks of culture. The elongated shoots rooted within 13 to 14 days on 1/2 strength MS medium supplemented either with indole-3-butyric acid (IBA), IAA or naphtylacetic acid (NAA) with 2% sucrose. Maximum percentage of rooting was obtained on medium having 0.25 mg/l IBA, 0.1 mg/l IAA and 2% sucrose. About 70% of rooted plantlets survived in the greenhouse. The in vitro raised plants were grown normally in the soil condition. This result will facilitate the conservation and propagation of the important medicinal plant.
