Opis:
The aim of the dissertation was to determine (select) the best growth medium for a basket willow (Salix viminalis L.) which contains optimal concentration of kinetin. The plant material taken from three varieties of willows: Bjor, Jorr and Tora, which grew in the experimental field, was sterilized and placed on a complete MS (Murashige and Skoog, 1962) growth medium. The propagated plants were used in an experiment, where MS substrate was enriched by growth regulator – kinetin, in various concentrations (0.5 mg∙dm-3, 1 mg∙dm-3, 2 mg∙dm-3 and 3 mg∙dm-3). The substrate which contained 0.5 KIN was considered to be the best for willow’s propagation, because plants cultivated with usage of this medium have shown the largest mass, the highest number of shoots and leaves, and also the highest quantitative and elongation growth of the roots. Among examined varieties of Salix, the best one was Bjor variety, where evaluated parameters were distinctive in comparison to two remaining varieties.

Opis:
The goal of the study was to check if the shape-describing characters, calculated as ratios of the morphological measured traits are more stable, compared to the latter, and can be treated as independent on environmental conditions. The test was based on the example of leaves of Salix herbacea and Betula nana. The individuals of the two populations of S. herbacea from Tatra Mts. were divided into two groups: with bigger and smaller leaves. The two populations of B. nana came from different substrata: the first one, collected from the mire on the lower altitude, had bigger leaves, and the second, collected from the granite plateau and higher altitude, had smaller leaves. For both species, the measured traits were generally more variable than the ratios calculated on their basis, as expressed by the variation coefficients. The results of Students' t-test analyses showed statistically significant differences between the two groups of S. herbacea and the two populations of B. nana with respect to almost all the measured characters, and no such differences for the calculated traits, reflecting the leaf shape. As the differentiation of the leaf size was probably bound to the environmental factors, the lack of the dependence of the leaf shape on the leaf size could lead to a conclusion of independence of the leaf shape on the environment conditions.

Opis:
Two previously unknown willow hybrids, Salix × velchevii (S. amplexicaulis Bory × S. xanthicola K.I. Chr.) and S. × ardana (S. alba L. × S. xanthicola K.I. Chr.), are described from the Bulgarian Rhodope Mts. This is the first report on hybridization in the endemic Balkan species S. xanthicola.
