    Opis:
    Grafting plays an important role in rhododendron propagation. Successful graft union depends on selection of a suitable stock, grafting season, and method. In this study, three methods (whip, cleft, and side grafting) were compared in two seasons. The stocks were mainly cuttings of R. catawbiense-Hybridum, R. ‘Cunningham's White', but also R. pachytrichum and R. brachycarpum. Scions were taken from several cultivars deriving from R. catawbiense. To shorten the production period, scions were grafted on unrooted stocks, and the results are encouraging. The best stock was R. ‘Cunningham's White', especially when side grafting was applied in spring.

    Opis:
    From past to the present, cultural, medicinal, landscape and culinary use of junipers has contrib- uted to it being one of the most widely distributed woody plants in the world. Therefore, it is so important that finding appropriate production methods to obtain quality seedlings in line with the usage area. In the present study, it was tried to determine the best conditions and applications on propagation by cuttings of three juniper taxa including Juniperus communis L. ‘Hibernica’, Juniperus chinensis L. ‘Stricta’, and Juniperus chinensis L. ‘Stricta Variegata’. For this purpose, two different greenhouse treatments (Greenhouse-1 with the air temperature at 20±2°C, rooting table temperature at 25±2°C and humidity level at 70±2%; Green- house-2 with the air temperature at 20±2°C, rooting table temperature at 20±2°C and humidity level at 70±2%) and different auxin applications (Indole-3-Butyric Acid, Indole-3-Acetic Acid and α-Naphthalene Acetic Acid at concentrations of 3000 and 5000 ppm) were designed. The highest rooting percentages were generally achieved in Greenhouse-1. IAA 5000 ppm treatment for J. communis ‘Hibernica’ (93.33%) and J. chinensis ‘Stricta’ (66.67%, also in Greenhouse-2) and IBA 3000 ppm treatment for J. chinensis ‘Stricta Var- iegata’ (60.00%) showed the best rooting results. This study, in which the best production conditions are investigated in some juniper taxa, is a guiding feature for the producers to ensure the sustainable utilization of junipers.

    Opis:
    Flowering and fruit setting was analyzed in specimens of Chamedaphne calyculata (L.) Moench growing in a natural stand in the “Sicienko” reserve in the Drawa National Park. Seed production, seed viability and shoot rooting was investigated. It was shown that Chamaedaphne calyculata has abundant flowers but sets few fruits. Numerous seeds (even up to 87) were found in fruits; however, the percentage of developed seeds was low and ranged from 17% to 45%. The viability of developed seeds was similarly low (maximum 29%). The performed germination test showed a positive effect of stratification on the breaking of seed dormancy. Obtaining seedlings from seeds sown in vitro on agar medium was a considerable success. Shoots cut perpendicularly to the shoot axis, with a 1-cm incision on the side and treated with a rooting agent, rooted 100%. Shoots which were not treated with a rooting agent, irrespective of their having been incised or not, rooted 78%.
