Opis:
Badano 54 odmiany piwonii chińskiej w pierwszym i drugim roku po podziale i przesadzeniu. Rośliny powstały w wyniku tradycyjnego podziału osobników matecznych w sierpniu 2002 roku. Na poletkach 1 m² posadzono po 4 rośliny poszczególnych odmian. Oceniono ich wzrost i kwitnienie w latach 2003 i 2004. Podział ten okazał się korzystny dla wszystkich odmian. Po dwóch latach uprawy rośliny każdej odmiany osiągnęły właściwe jej cechy. W pierwszym roku (2003) najdłużej - 92 dni rosły odmiany ‘Avalanche’ i ‘Mlle Rousseau’, a w drugim (2004) - 106 dni - ‘Avalanche’ i ‘Mme Vatryl' oraz 105 dni - ‘Baroness Schröder’. Najwyższe i gęsto ulistnione w obydwóch latach były odmiany ‘Conquette’, ‘Dermonth’ i ‘Adolphe Rousseau’, a najniższą ‘Albert Crousse’. W 2003 roku najobficiej kwitły odmiany ‘Compt de Niepperg’ i ‘Dermonth’, a w 2004 roku ‘Lady Anna’ i ‘Jadwiga’. Największe kwiaty o średnicy przeszło 14 cm w obydwóch latach miała odmiana ‘Torpilleur’, Czas trwania kwitnienia zależał od odmiany i przebiegu pogody. W obydwóch latach do najdłużej kwitnących należała odmiana ‘Avalanche’, a do najkrócej ‘Prof. Wóycicki’. Kwitnienie wszystkich odmian trwało około 30 dni. Do uprawy w polu na kwiaty cięte można zalecać odmiany ‘Albatre’, ‘Dorchester’, ‘Empereur Nicholas’, ‘Mlle Leonie Calot’, ‘Baroness Schröder’, ‘Jadwiga’, ‘Mme Vatryl’ i ‘Ursyn Niemcewicz’.
54 cultivars of Chinese peony were studied in the first and second year after division and transplanting. The plants were obtained through the traditional division of stock specimens in August 2002 and planted in plots 1 m² in area, four plants per plot. Their growth and flowering were assessed in the years 2003 and 2004. The division turned out to be successful for all the cultivars: after two years of culturing the plants, each of them achieved their characteristic properties. In the first year (2003) the longest-growing cultivars included ’Avalanche’ and ’Mlle Rousseau’ (92 days), and in the second (2004), ’Avalanche’ and ’Mme Vatryl’ (106 days) as well as ’Baroness Schröder’ (105 days). In both years the highest cultivars, and cultivars with dense foliage, were ’Conquette’, ’Dermonth’ and ’Adolphe Rousseau’, and the lowest, ’Albert Crousse’. In 2003 the cultivars that flowered most abundantly were ’Compt de Niepperg’ and ’Dermonth’, and in 2004 ’Lady Anna’ and ’Jadwiga’. In both years the cultivar that produced the largest flowers, more than 14 cm in diameter, was ’Torpilleur’. The flowering time depended on the cultivar and weather pattern. In both years the cultivar that bloomed the longest was ’Avalanche’, and the shortest, ’Prof. Wóycicki’. The flowering lasted for about 30 days in all cultivars. Those that can be recommended for cut flowers in the field culture include ’Albatre’, ’Dorchester’, ’Empereur Nicholas’, ’Mlle Leonie Calot’, ’Baroness Schröder’, ’Jadwiga’, ’Mme Vatryl’ and ’Ursyn Niemcewicz’.

Opis:
The impact of light quality generated by light-emitting diodes (LEDs) on the adventitious root formation and cuttings’ quality of rose hip ‘Konstancin’ under controlled conditions in multilevel growth chamber without access to natural light and in the greenhouse was evaluated. In the growth chamber, the lighting was provided by a combination of red and blue LED arrays and white LED tubes, while in the greenhouse, red and blue LED lights were used as a supplement to natural light. The number of rooted cuttings under both growth conditions was not affected by the light conditions generated by LEDs. However, light quality showed significant effects on the biomass production and development of adventitious roots, with the most stimulating red light generated by LEDs. In the growth chamber, the root biomass of the cuttings illuminated with white LEDs supplemented with red LEDs was on average 2.2 times higher than of the cuttings illuminated with white LEDs only. A similar reaction was noted under greenhouse conditions. Supplementation of natural light with red LEDs resulted in 1.7 times increase of the fresh biomass of roots. Both in the growth chamber and in the greenhouse, illumination with red LEDs promoted axillary bud outgrowth. LED lamps can be used in the production of high-quality rose cuttings, both in greenhouses as a complement to natural light and in multilevel rooms as a sole-source lighting for plants.

Opis:
Bamboo is an important source of income for rural livelihoods in Ethiopia and somewhere else. It is increasingly recognized as potential species for environmental protection and poverty reduction in many countries including Ethiopia. The study was conducted in Amhara Regional State, Awi Zone, where Yushania alpina dominated areas of Banja district. This finding aimed at to identify advanced propagation techniques that can be pertinent for large scale plantation of Yushania alpina. randomized complete block design with three replications was used. The vegetative propagation materials (treatments) were; rhizome with two nodes, rhizome with four nodes, rhizome with six nodes, rhizome without culm and rhizome with the whole culm (offset). A total of 240 offset planting materials were planted in the experimental station. Of which, sixteen planting material were used in each plot level. New shoot sprouting, and their height, root collar diameter and mortality rate data was collected. There was no statistical significant difference in mean number of new sprouted shoots of Yushinia alpina between the five treatments. While, there was significant difference between mean shoot height of rhizome with four nodes and rhizome without Culm (137.02b ± 22.94, 67.10a ± 17.97) at (p<0.05) respectively. The result revealed that, rhizome with four nodes and six nodes had shown significantly higher mean shoot height and root collar diameter, as compared with the traditional one (Rhizome with the whole culm) (33.89b ± 12.17, 32.43b ± 12.68, 8.48a ± 2.53) at (p<0.05) respectively. The present finding confirmed that, among different Propagating techniques rhizome with four and six nodes are appropriate for large scale plantation of Yushinia alpina, as compared to the conventional propagation technique (offsets).

Opis:
Nasady młodych, wyrastających pędów traktowano preparatem Ukorzeniacz B2, stymulującym rozwój korzeni przybyszowych. Następnie wokół pędów usypano kopczyki z mieszanki torfu wysokiego i gleby ogrodowej. W miarę wzrostu pędów kopczyki podwyższano do ostatecznej wysokości 25 cm. Po jednym okresie wegetacyjnym odcięto ukorzenione odkłady z połowy roślin kopczykowanych, a po dwóch okresach wegetacyjnych – z pozostałych roślin. Oceniono jakość ukorzenionych odkładów, a wiosną 1998 i 1999 roku wyrosłe z nich nowe rośliny. Pędy piwonii kopczykowane w ciągu jednego okresu wegetacyjnego ukorzeniły się przeciętnie w 85,2%, a kopczykowane dwa okresy wegetacyjne – w 75%. Lepszą jakością ukorzenienia charakteryzowały się odkłady dwuletnie. Z wszystkich ukorzenionych odkładów, niezależnie od czasu trwania kopczykowania nowe rośliny rozwinęły się u odmian ‘Avelanche’, ‘Lady Dormouth’ i ‘Reine Hortense’. Odmiany te oraz inne, których odkłady ukorzeniły się w przeszło 70%, tj. ‘Baroness Schröder’, ‘La Rosière’, ‘Marechal McMahon’, ‘Monsieur Jules Elie’, ‘Profesor Wóycicki’, ‘Thérèse’ i ‘Ursynów’ można rozmnażać za pomoc odkładów pionowych.
Bases of young shoots were treated with the Ukorzeniacz B2, preparation stimulating adventitious roots development. Then piles of a mixture of white peat and hortisol were made around the shoots. The shoot growth was accompanied by increasing the height of piles. After one vegetative period the rooted layers were removed off from half of the piled plants, and after two vegetative periods – from the other plants. The quality of the rooted layers was estimated and in spring 1998 and 1999 new plants grew from them. On average 85.2% of Paeonia lactiflora Pall. shoots piled over one vegetative period, and 75% of those piled over two vegetative periods took roots. A higher rooting quality was recorded in two-year layers. Regardless of the piling period, new plants were developed from the all rooted layers in ‘Avelanche’, ‘Lady Dormouth’ and ‘Reine Hortense’ cultivars. These and other cultivars whose layers rooted in over 70% cases, i.e. ‘Baroness Schröder’, ‘La Rosière’, ‘Marechal McMahon’, ‘Monsieur Jules Elie’, ‘Profesor Wóycicki’, ‘Thérèse’ and ‘Ursynów’, can be propagated with vertical layers.

Rootability of Dalbergia sissoo Roxb. cuttings of mature tree originated clonal hedge bed were tested and compared to the same from seedling originated hedge bed. Mature tree originated cuttings were found potential for rooting in low-cost non-mist propagator without any rooting hormone. Steckling growth in nursery and in the field was found promising which is a complete indication for its successful application by tree planters. It will be a new research avenue to get disease free germplasm for the frustrated plantation managers and scientists due to die back of this tree through out the South Asian region.

Opis:
In this study, we present investigations of morphological changes in the inflorescence of bolting Allium sativum L., which forms umbel-like inflorescences with small, inconspicuous flowers, bulbils, and leaf-like membranous bracts. Particular attention was focused on the architecture of a single flower, and the full sequence of developmental events and the differentiation of flower elements and inflorescence were traced. During the several-year long investigations of the garlic species, we observed that all inflorescence elements emerged chaotically, taking a completely random place in the inflorescence receptacle and it was impossible to identify the sequence of formation of the individual inflorescence elements. The absence of regular phyllotaxis and the specific sequence of formation of inflorescence elements are characteristic for inflorescence reversion. Since domesticated garlic has lost the capacity for sexual reproduction, it has probably evolved alternative reproduction modes in its developmental strategy, which is reflected by the formation of numerous bulbils (vegetative buds, topsets) in the inflorescence. This is one of the forms of reproductive strategy of the species, which through domestication progresses from sexual to asexual reproduction.

Opis:
A method for vegetative propagation of Moringa concanensis was developed in the present study. Stem cuttings were collected from wild populations in Tamil Nadu. The cuttings with 2-4 nodes were treated with various concentrations of Indole Butyric acid (IBA), Indole Acetic Acid (IAA) and α-Naphthalene Acetic Acid (NAA) for 5 min. The effectiveness of auxins on shoot bud induction and rooting response of stem cuttings was in the order of IBA>NAA>IAA. The auxin treated cuttings were planted on planting media and placed in the greenhouse. The survival rate and relative growth rate of stem cuttings were analyzed at every 4 week interval for 24 week. Stem cuttings treated with 250 mg/L IBA was responded better and survived for two years. Indole-3 acetic acid treated stem cuttings initiated branches within 7 weeks but very few branches arose. The cuttings treated with NAA responded with less relative growth than IBA. This method proves the rooting ability of IBA and growth performance of stem cuttings, which can be used for the mass propagation and conservation of this rare medicinal plant to prevent the exploitation from the wild.

Opis:
So far, experience in the existing clonal seed orchards of Douglas-fir indicates that grafts of this species are short-lived. According to research carried out in North America, incompatibility between the grafted scions and the rootstocks happens during the whole period of growth and development in clonal seed orchards of Douglas-fir. A similar phenomenon occurs in the clonal seed orchards of Douglas-fir in Poland. The extent of die-back of grafts was examined in three existing oldest units in the Forest District of Gniewkowo (founded in 1992-1993; 2.80 ha), the Forest District of Leżajsk (founded in 1995, 4.22 ha) and the Forest District of Łopuchówko (founded in 1993, 7.43 ha). In all these areas, losses due to die-back ranged from a dozen to a few dozen per cent. Die-backs in the clonal seed orchards in the Forest District of Gniewkowo and in the Forest District of Łopuchówko are now reduced to as much as about fourty per cent of grafts. Analyses of die-back in all these areas reveal great variation between individual clones, indicating its genetic basis. Research carried out so far has not demonstrated the presence of any pathogens responsible for causing the die-back in the grafts. Some hope to solve the problem mentioned above arises from attempts at autovegetative propagation of Douglas-fir.
