The farmers are allowed, under certain conditions, to use seeds from harvest for sowing. Only the breeder who holds an exclusive right to a plant variety can reproduce it and offer for sale. The breeder can make an agreement with a seed company and sign a license contract. Commercial preparation for sowing or planting a variety protected by an exclusive right also requires breeder’s consent.

The functioning of forests in Poland is often associated with a productive role and the production of wood-based raw materials, disregarding the need to protect forest environments. In practice, the approach to the protection of nature and animals, including insects in forest areas, has changed in recent decades. Many researchers still point to the need to protect the processes taking place in forest environments. Actions are being taken to reduce monocultures in forests and to increase the biodiversity of plants and animals living among crops. A good example described in this paper is the relationship between seed plantations and insects. These relationships may have a positive effect on the fruiting process and seed production in selected tree species. This paper presents an example of the relationship between wild bees and Prunus avium L. seed plantations as an example of a positive relationship in which humans as well as pollinating insects can benefit. The structure and size of Prunus cultivation in Poland are described and the hitherto harvest of seeds is analysed. The elements of the biology of the Prunus species, important for the process of pollination of flowers by insects are also indicated. The study also indicates ways to protect bees in the forest environment.

Celem badań było określenie możliwości uprawy roślin warzywnych na nasiona w aspekcie fitopatologicznym. Wykazono możliwość otoczkowania nasion z wykorzystaniem biopreparatu opartego na grzybie Trichoderma viride dla ochrony siewek przed chorobami zgorzelowymi. Przy zachowaniu odpowiedniej technologii, w jednej otoczce znajdowało się 250 żywych jednostek tworzących kolonie grzyba (jtk). Najlepszy efekt uzyskano zaprawiając nasiona w wodnej zawiesinie biopreparatu i dodając pozostałość zawiesiny po zaprawianiu do komponentów w trakcie otoczkowania. Ważnym elementem jest czystość mikrobiologiczna stosowanych komponentów. Opryskiwanie biopreparatami w okresie wegetacji celem ochrony przed chorobami dawało zróżnicowane wyniki. Najlepszy efekt uzyskano w ochronie cebuli przed mączniakiem rzekomym (Peronospora destructor) stosując kilkakrotne opryskiwanie Bioseptem. Zebrane nasiona buraka ćwikłowego i marchwi jadalnej zasiedlone były licznie przez patogeny grzybowe. W trakcie czyszczenia większość zasiedlonych przez patogeny nasion została wyeliminowana ale ubytki byty znaczne.

The aim of studies was evaluation of possibility of vegetable seed production from the phytopathological point of view. It was found that there is a possibility of seed coating with biopreparation based on fungus Trichoderma viride in order to protect seedlings from rot diseases. When a proper technology was used, 250 living cfu (colony forming units) were present in single coat. The best results were obtained after seed treatment with water suspension of biopreparation with addition of remains of suspension after treatment into components of coats. Microbiological cleanliness of coat components is also of a great importance. Sprayings with biopreparations during cropping season resulted in differentiated degree of pathogen development limitation. The best results were obtained in the case of downy mildew (Peronospora destructor) of onion after several sprayings with Biosept. Harvested seeds of red beet and carrot were numerously settled with fungal pathogens. During cleaning of seeds, most of them was removed but losses were considerable.

The advantage of the clonal plants over the nonclonal species in colonization of all biomes and biogeographical regions primarily is due to occurrence of two modes of reproduction. The creating of vegetative propagules with high vitality and survivability, enables the spread in the newly colonized site, while seed production increases the chances for successful recruitment of seedlings, ensuring the genetic diversity of the population. The differences in allocation into vegetative reproduction and generative propagation in relation to rising height of adjacent plants was investigated in populations of Serratula tinctoria L., occurring in Molinietum caeruleae meadows localized in Southern Poland. Each locality was represented by randomly established three permanent study plots: dominated by small meadow species (LOW), prevailed by large-tussock grasses (INTER) and overgrown by shrubs and trees (HIGH). In the years 2009–2011 the number of leaf rosettes and length of the longest leaf in rosette (as a measure of allocation in vegetative propagation), as well as height of generative stems, number of capitula per stem and number of seeds per capitulum (as indicators of investment in generative reproduction) were observed. The allocation in vegetative reproduction decreased along the gradient of vegetation height. The gradually decline of number of rosettes might be caused by lack of free space suitable for establishment of new ramets, whereas the small leaf size could be due to drastically augmentation of shading. The allocation in generative reproduction increased along the gradient of vegetation height. The placement of structures necessary for generative propagation in higher layers of herbaceous canopy, as well as considerable number of capitula and seed production might increase the chances for successful recruitment of seedlings. On the basis of obtained results combining with published data it should be assumed, that the substantial allocation in vegetative reproduction and the slight investment in generative propagation seems to be sufficient for persistence of Serratula tinctoria populations in patches dominated by small meadow species, while the considerable allocation in generative reproduction could be crucial for maintenance of population viability under competitive conditions.

The aim of this research was to study the effect of stecklings planting density on the seed stalk architecture, cluster yield and seed quality of 20 mono - and multigerm breeding lines and cultivars of red beet. The study included the new monogerm lines - AR79 A and AR79 B - breed in the Unit of Genetics Plant Breeding and Seed Science at the University of Agriculture in Kraków. The experiment was conducted in the years 2010 and 2011, in the open field conditions. Two planting densities of stecklings: 50×25 and 50×40 cm, were applied. Standard crop management practices, as recommended for red beet seed production under Polish conditions, were followed. The increase in plants interspacing from 50×25 to 50×40 cm led to the lower height, but twice higher number of shoots per plant, lower number of single, but higher number of bush and bush with main stem seed stalks, twice higher yield per plant as well higher thousand-seed weight and germination capacity. A large variation between genotypes in the features of seed-bearing plants, such as morphological structure, clusters yield and seed quality, were noted. Compared to other genotypes, the new monogerm breeding lines AR79 A and AR79 B formed very high, mostly bush or bush with main stem seed plants developing one of the largest numbers of unluckily, late-ripening shoots, yielded on the average level and producing the seeds of relatively low quality. The research has expanded the knowledge about the generative development of red beet. The results will facilitate Polish breeding programs aimed at the selection of monogerm red beet lines.

In 2004, abundant flowering of Norway spruce (Picea abies (L.) Karst.) was observed in two second- generation seed orchards: (1) ‘Outbreeding’, promoting crossing between clones of five geographically distant populations; and (2) ‘Kolonowskie’, restoring a population whose offspring exists only in an international experiment (IUFRO 1964/1968). In bothseed orchards, female strobili were produced by 91.3% and 91.7% of clones, represented by 64.1% and 55.5% of grafts, respectively, and statistically significant differences between clones were found in the number of mature cones. In the case of the seed orchard ‘Outbreeding’, the number of mature cones in individual clones was significantly correlated with latitude of the origin of maternal populations (r = 0.8826, p = 0.0470). The majority (95%) of cones in seed orchards ‘Outbreeding’ and ‘Kolonowskie’ were produced by only 28.2% and 38.5% of all clones, and 21.4% and 25.7% of all grafts, respectively. These data attest to a disparity between the level of genetic diversity in seed orchard progeny resulting from the observed numbers of cone-bearing clones and grafts and the genetic diversity expected from the actual participation of clones and grafts in seed orchard composition. The estimated seed production per 1 ha of seed orchard area in 2004 reached 21.05 kg for ‘Outbreeding’ and 21.72 kg for ‘Kolonowskie’.

A strict two-factor field experiment was set up as a randomized complete block design over 2000-2002 at the Experimental Station of the Faculty of Agriculture, University of Technology and Agriculture, at Mochełek, and involved a traditional yellow lupin cultivar, `Idol´, whose plants were sprayed with Tytanit preparation, containing 46% of Ti. The first factor covered the following objects: three spraying dates: single spraying after blossom fall, double spraying - after blossom fall and 7-10 days later and triple spraying - after blossom fall, 7-10 days later and then 7-10 days later. The second factor involved the following objects of Tytanit concentration: 0.02, 0.04 and 0.06%. The plots which were not sprayed constituted the control. Throughout the research years there was observed a significant effect of Tytanit on 7.4-18% increased yellow lupin seed yield. Tytanit did not show a significant effect on the structural components of the seed yield from the main stem; its application resulted in a significant, as compared with the control, increase in the number of pods and seeds as well as in the seed weight from branches. As for yellow lupin yielding, the optimal solution seems to be offered by a double application of 0.02-0.04% of Tytanit straight after plant blossom fall and 7-10 days later.

Parasitic plants species of the genus Orobanche produce a very high number of small dust-like seeds. The seed shape of Orobanche sp. is ellipsoid to globose, ca. 0.3 × 0.4 mm. Orobanche picridis F.W. Schultz is a sub-Mediterranean-sub-Atlantic species. It has the NE range limit in Poland and Ukraine. The species is seriously endangered in Poland and neighbouring countries. O. picridis occurs only in southern Poland (34 localities). It prefers habitats on chalky rendzina, especially S-facing. It colonizes abandoned fallows and wastelands, field margins, initial xerothermic grasslands. They are mostly ecotone communities, in semi-ruderal xerothermic pioneer communities belonging to the Dauco-Picridetum (Artemisietea vulgaris class). The aim of this study was to determine potential and real seed productivity in Orobanche picridis and correlations between the characteristics of the shoots. Research hypothesis is to show that the studied traits of shoots show the highest correlation with the production of seeds. The paper presents investigations into potential and real seed productivity of Orobanche picridis for the first time. Investigations were conducted in 2010 at three most abundant localities of O. picridis in southern Poland in the Wyżyna Małopolska upland (S Poland) - Wesołówka (Przedgórze Iłżeckie foreland), Pińczów, and Pęczelice (Niecka Nidziańska basin). Research into the number of seeds produced per fruit and per shoot is discussed. Strict correlations between seed productivity and shoot features, i.e. shoot height, inflorescence length, number of fruits and corolla tube length were observed. The number of seeds in a single ovary in O. picridis varied and ranged from 457 to 3 246. The mean number of seeds per shoot is 55 172 based on the data collected at the three sites and ranges between 8 911 and 151 050. Seed productivity depends significantly on the size of a plant, that is on the shoot height, correlation coefficient r = 0.7, inflorescence length, r = 0.6, number of flowers and fruits per plant, r = 0.6, and on the flower size, r = 0.5.
