The research was aimed at establishing the degree to which wild boar used different parts of habitats in a large forest complex. In the Zielonka Game Investigation Centre, wild boar most actively rooted from October to March, in fresh mixed broadleaved forest and fresh broadleaved forest, in stands aged over 41 years.

The wild boar is an omnivorous animal, and by foraging (rooting) disturbs the top soil layer. In some regions of Poland and Europe seasonal fluctuations in rooting have been observed. Wild boars not only eat plants, but also strongly modify their habitat. In Białowieża National Park wild boar most frequently visit oak-hornbeam forests on fertile soil. On sites where the forest floor is covered with dense vegetation the germination of seeds is difficult, and wild boar rooting can promote the removal of diaspores from deeper layers of the soil seed bank. Within a 3-year observation on 30 subplots about 10,000 seedlings emerged representing 38 species. Our study revealed that rooted patches are characterised by a very rich and diverse flora of seedlings representing mostly forest species, but their density is low. The dominant species germinating in the disturbed ground vegetation is Urtica dioica, a species forming the persistent soil seed bank. There is a possibility that seedlings of herbaceous plants emerging on permanently rooted patches are of exogenous origin, since the seeds germinating there were in many cases damaged by repeatedly rooting animals and had no chance for further growth and reaching the generative phase. However, the soil seed bank in the rooted area has to be analysed to confirm this theory, that they have exogenous or endogenous origin. Seedling density in a repeatedly rooted oak-hornbeam forest is determined by factors other than those related to rooting. In this context the present study did not demonstrate a negative impact of rooting intensity on seedling emergence.

Propagation of juniper from cuttings is the primary method used in the nursery. Process of rhizogenesis in these plants is long and not always allows to obtain a good quality of rooted cuttings. In the experiment there was investigated the effect of laser light doses (semiconductor laser, model CTL 1106MX, power 200 mW, wave length 670 μm) and the footing agent AB on percentage of rooted cuttings, plants height, length and the number of roots. The examined juniper taxa proved diverse response to the variants applied (combination of laser radiation and the rooting agent AB). The increase in the number of rooted cuttings after application of the rooting agent AB, as well as three times introduced irradiation in Eastern redcedar ‘Blue Arrow’. This form also produced longer roots for the variant combining twelve times applied irradiation and the effect of rooting agent. In the cuttings of Chinese juniper ‘Stricta’, exposed to laser radiation in six – (D6) and twelve times applied doses (D12), there was observed significant stimulation of root length. Introduced treatment variants of shoot cuttings of Common juniper ‘Schneverdinger Goldmachangel’ brought about considerable root elongation (except for D3 dose). The dose providing for significant increase in the percentage of rooted cuttings in all the examined juniper varieties proved to be D3 dose.

A trumpet creeper (Campsis radicans) is an attractive vine propagated vegetatively through cuttings. So far, there is very little available data on propagation of this beautiful species in tissue culture. There was a research conducted in order to estimate the possibility to obtain rooted Campsis radicans plants that had been cultivated in tissue culture. The plant material were shoots obtained by multiplication on Murashige and Skoog [1962] (MS) medium which were put in fresh media supplemented with auxins: IAA (indoleacetic acid), IBA (indolebutyric acid) or NAA (naphthaleneacetic acid). The shoots were rooted in vitro or transplanted into soil (peat + perlite 1 : 1 w/v). It was noted that Campsis radicans is a very difficult plant to root in tissue culture. No rooting was obtained in vitro. Use of a stimulating passage with a hormone free medium or the ones containing IAA or IBA in concentrations of 2.5–5 mg·dm-3 and rooting shoots directly in soil allowed to obtain 100% of well rooted plants.

Cuttings of R. ponticum were treated or not with ‘Ukorzeniacz AB’ containing IBA and NAA, and placed in rooting medium (temp. 21°C). Transverse sections were made of the bases of the cuttings removed from the soil after 2; 3; 4; 5 and 6 weeks. Meaningful anatomical changes in anatomical structure of R. ponticum cuttings connected with wound-healing process could be seen during rooting. In first two weeks periderm in cortex and callus from cambium and phloem emerged as a response to wounding of cuttings. After 3 weeks initiation of wound xylem started in callus. It developed very intensively and did not depend on the way of cutting treatment. Application of auxins did not or not considerably influenced the anatomical changes in stem structure of R. Ponticum during rooting – proliferation of new xylem was similar in control cuttings and in cuttings treated with rooting stimulator ‘Ukorzeniacz AB’, although it stimulated initiation of root primordia. Adventitious root formation occurred only in cuttings treated with ‘Ukorzeniacz AB’, in which numerous root primordia could be observed after 3 and more weeks of rooting. In control cuttings there was none of them even after 6 weeks of rooting.

Strawberry is propagated vegetatively. Nowadays, traditional bare-root transplants are often replaced with plantlets (plug plants) produced from runner tips. The nutrient level and type of growing medium may influence the quality of planting material. Phosphorus and potassium are important elements for plant metabolism. Insufficient supply of plants with these elements negatively influences the rooting and plant vegetative growth. The objective of the study was to evaluate the influence of substrate and monopotassium phosphate (MKP) on rooting and quality of strawberry plantlets grown in the greenhouse soilless system. ‘Elsanta’ mother plants were planted in containers and set on a special rack in the greenhouse. Emerging plantlets were set (clipped with metal clips) in micro-pots filled with peat or coconut substrate. Four concentrations of MKP in the growing medium were applied: 0, 0.22, 0.44, 0.66 g dm-3. Rooting of plantlets was carried out before cutting them off from the mother plants for a period 7, 10 or 14 days. The investigations have showed a very similar dynamics of root formation both in coconut substrate and in peat. A significant effect of the application of monopotassium phosphate on rooting of strawberry plantlets was observed. The optimal dose of MKP depended on the length of rooting period of plantlets. After 7 days of rooting the highest root weight was recorded in case of plantlets rooted in the growing media supplemented with 0.44 or 0.66 g dm-3 MKP. After 10 and 14 days of rooting even the lowest dose of MKP (0.22 g dm-3) resulted in significantly stronger root growth in comparison with not fertilized control plantlets. MKP also significantly influenced the growth of plantlets after transplanting them into bigger containers. The highest quality plantlets were obtained at the dose 0.44 or 0.66 g MKP dm-3 of substrate.
