    Opis:
    The aim of the studies was to establish in vitro conditions for the culture of pea and lupin embryos as the first step in the development of an in vitro assisted single seed descent technique for the attainment of homozygous populations. Materials for the study included of pea, and narrow-leafed and yellow lupin cultivars. Embryos dissected from mature but still-green seeds were cultured in vitro on two modified MS media and under three temperature regimes. Shoot and root lengths of regenerated plants were measured after 7, 14 and 21 days of culture. For pea plants full-strength MS medium with 4 g l−1 agar and temperature 22/ 20°C (day/night) appeared to be the most conducive to shoot and root development, whereas for lupin plants lower temperatures were more propitious: 12°C in the dark for narrow-leafed lupin and 16/ 12°C (day/night) for yellow lupin. Almost all the cultured embryos developed into plants, but not all the regenerated plants survived acclimation to ex vitro conditions.

    Opis:
    The aim of this study was to compare the accumulation of soluble carbohydrates in embryos of two lupin species: cultivated Lupinus luteus (cv. Juno) and wild L. pilosus, developing on plants grown under normal soil humidity and soil drought. All analysed seeds accumulated soluble carbohydrates, including: monosaccharides, sucrose, cyclitols, galactosyl cyclitols and raffinose family oligosaccharides. Soil drought caused a nearly two-fold increase of soluble carbohydrate contents in both species. L. pilosus embryos however, responded to water deficiency by increasing the accumulation of cyclitols and galactosyl cyclitols, whereas L. luteus embryos enhanced accumulation of cyclitols and raffinose family oligosaccharides.

    Opis:
    Yellow lupin seeds cv. Juno were stored under laboratory conditions for 2 month, 4, 6 and 8 years. Eighteen soluble carbohydrates were identified in embryonic axes and cotyledons of different age seeds. The concentration of soluble carbohydrates in analysed seeds ranged from 25 to 34% of dry mass. Axes contained more carbohydrates than cotyledons. Stachyose dominated in axes, and verbascose - in cotyledons. Other detected galactosides were: galactinol, galactosyl pinitols and galactosyl chiro-inositols (fagopyritols), but their content was several-fold lower than that of RFOs (in both axes and cotyledons tissues). The concentration of soluble carbohydrates indicated, that sucrose to RFOs mass ratio, or other changes in sugars composition are not indicators of seed storage.

    Opis:
    The aim of the research was to determine changes in the chemical composition in lupin seeds during seed germination in a solution containing selected nitrogen compounds. Blue lupin seeds of the Neptun cultivar were germinated for 3 or 4 days in darkness, at 24°C in 1% solutions containing the following nitrogen compounds: urea, nitric acid, ammonium sulphate, methionine or yeast extract. The control consisted of seeds germinated in water. The presence of all nitrogen sources has resulted in a poorer growth of the sprouts as compared to seeds germinated in water. There was a significant increase in the true protein content as well as a significant decrease in the content of crude ash and alkaloids in the germinated seeds. The seeds germinated for 4 days had significantly higher total protein content and significantly lower content of nitrogen-free extract compounds and oligosaccharides as compared to the seeds germinated for 3 days. A significant influence of the nitrogen source on the concentration of some amino acids was found. Cystine was found to be absent in seeds germinated in the nitric acid solution, while there occurred a twofold increase in the cystine content and a fivefold increase in the methionine content in seeds germinated in the aqueous solution of methionine and an 50% increase in the cystine concentration was observed in seeds germinated in the yeast extract and ammonium sulphate solution. Methionine and cystine were the limiting amino acids in all the samples, accept of seeds germinated in the methionine solution were it was valine. Aqueous solutions of ammonium sulphate and yeast extract were found to have the most advantageous influence on the chemical composition of lupin germination products.

    Opis:
    The influence of different nitrogen forms: (N2), [N2+(NH4++NO3-)], (NH4+), (NO3-), (NH4++NO3-) and (-NH2) on changes of albumin, globulin, prolamin-glutelin, non-fractioned nitrogen and non-protein nitrogen fractions of the protein seed of alkaloid-low content Lupinus albus L. cv. Butan has been studied. The experiments were performed in a greenhouse on perlite using in all cases the constant P, K, Mg and micronutrients (B, Zn, Mn, Cu, Mo, Fe) fertilization. The control was the treatment without any nitrogen support (Nd). It was clearly shown that nitrogen form has significant effect not only on the seed yield and seed protein content, but also on the composition of protein fractions and on the biological value of lupin protein. The main protein fraction of the seeds from all treatments were albumins (16.73-26.10 mgN/g). Among all the treatments, the highest level of globulin was observed for the seeds of plant growing with the symbiotic nitrogen form (15.26 mgN/g), while the lowest one for the control (Nd) (6.86 mgN/g). Symbiotic nitrogen (N2) treatment clearly increased the glutelin-prolamin fraction while the addition of mineral nitrogen (NH4++NO3-) decreased this fraction from 8.40 to 4.48 mgN/g. The lowest level of the glutelin-prolamin fraction was in the absence of any nitrogen (Nd). Non-protein fraction (Nnp) was highest in the case of plants treated with (-NH2) (9.92 mgN/g), and the lowest in the absence of nitrogen (Nd) (4.90 mgN/g). The level of non-fractioned nitrogen (Nr), with exception of [N2+(NH4++NO3-)] and -NH2 treatments, was closest to the start material. The protein fractions (albumins, globulins and glutelins and prolamins) were also electrophoretically characterized. These analysis confirmed the changes in protein composition of particular fractions under the effect of various nitrogen forms used as a fertilizer.

    Opis:
    This article present a comparison of soluble sugar levels in seeds of Lupinus atlanticus, Lupinus cosentinii, Lupinus palaestinus and Lupinus pilosus, Lupinus hispanicus subsp. hispanicus and Lupinus luteus of Juno variety. Considering that sugars are accumulated in embryos, only the embryonic tissues were used for biochemical analyses. Additionally, the share of testa and embryo in seed tissues was evaluated. The seed-coat thickness was measured using scanning electron microscopy. The seed coat had the largest share in seeds of Lupinus pilosus and Lupinus palaestinus, and the least share in seeds of Lupinus hispanicus subsp. hispanicus and Lupinus luteus of Juno variety. In the seed of Lupinus pilosus the thickness of the seed coat was 1100 µm, while in Lupinus luteus it was 300 µm. The analysed Lupinus seeds accumulated from 73 mg/g d.m. (dry matter of seed embryo) to 155 mg of soluble sugars/g d.m. The highest quantity of oligosaccharides of the raffinose series was found in seeds of Lupinus luteus, while the lowest amount in seed of Lupinus palaestinus. Galactosyl cyclitols appeared in largest amount in seeds of Lupinus palaestinus and Lupinus pilosus, appropriately 41.93 and 33.75 mg/g dm. The lowest amount of galactosyl cyclitols appeared in Lupinus atlanticus, Lupinus cosentinii and Lupinus hispanicus.

    Opis:
    In 1999-2001 the effect of sowing method and plant density on the sanitary state of three cultivars of yellow lupine protected with fungicides against diseases was investigated. In spring of 2000 the seedlings on the experimental fields generally withered, which was most likely caused by the applied herbicide, however in 1999 and 2001 seedling black leg (complex of fungi) was reported. The plants germinating from the seeds sown in points were clearly less attacked by pathogens evoking seedling black leg than those sown in rows. The most serious disease of yellow lupine was antracnose (Colletotrichum gloeosporioides). It occurred in all experimental years and its intensity increased during vegetation period. Cultivars of lupine used to the experiment were attacked by Colletotrichum gloeosporioides in a different degree, however, the injury index was mainly determined by weather conditions and the lupine development phase. The applied fungicides significantly limited the development of lupine antracnose. The effect of sowing method and varied plant density on disease intensity was varied.
    W latach 1999-2001 przeprowadzono badania dotyczące wpływu sposobu siewu oraz obsady roślin na zdrowotność trzech odmian łubinu żółtego w warunkach chemicznej ochrony przed chorobami. Wiosną 2000 roku na poletkach doświadczalnych wystąpiło ogólne marnienie siewek spowodowane prawdopodobnie działaniem użytego w doświadczeniu herbicydu, natomiast w latach 1999 i 2001 roku odnotowano zgorzel siewek (kompleks grzybów). Rośliny kiełkujące z nasion wysiewanych punktowo były zdecydowanie słabiej atakowane przez patogeny powodujące zgorzel siewek niż siane rzędowo. Najgroźniejszą chorobą łubinu żółtego okazała się jednak antraknoza łubinu (Colletotrichum gloeosporioides). Występowała we wszystkich latach badań, a jej nasilenie w okresie wegetacji wzrastało. Uprawiane w doświadczeniu odmiany były w różnym stopniu atakowane przez Colletotrichum gloeosporioides, jednak indeks porażenia zależał przede wszystkim od przebiegu pogody i fazy rozwojowej łubinu. Zastosowane fungicydy ograniczyły rozwój antraknozy łubinu. Wpływ sposobu siewu i zróżnicowanej obsady roślin na nasilenie choroby był niejednoznaczny.

    Opis:
    The object of the experiment were seeds of two traditional cultivars of yellow lupin (Juno and Amulet) cultivated in 1999 in two crop-rotation with 20% and 33% yellow lupine contribution. The quantitative and qualitative composition of the fungal community colonizing the seeds were determined in the laboratory conditions after 0.5-, 1.5- and 2.5-year of storage time. In total 1077 fungal colonies were isolated from the lupin seeds. Fungi representing the species of Penicillium - 29.3%, Alternaria alternata - 26.7% and Rhizopus nigricans - 12.7% were isolated most widely. Among the fungi pathogenic to lupin, the species of Colletotrichum gloeosporioides (16.3% isolates) was dominant. The crop rotation with 20% lupin reduced the number of fungal colonies colonizing the seeds including the pathogens from the species of C. gloeosporioides. Seed disinfection decreased the total number of fungal colonies isolated from both cultivars. Higher number of C. gloeosporioides isolates was found in the combination with disinfected seeds. More fungal colonies were obtained from seeds of cv. Amulet than from those of cv. Juno. The storage duration had an effect on the population and the composition of species of fungi isolated from seeds of yellow lupine. With longer storage population of Penicillium spp. and Rhizopus spp. increased, whereas the population of C. gloeosporioides decreased.
    Przedmiotem badań były nasiona dwóch odmian łubinu żółtego (Juno i Amulet) uprawianych w roku 1999 w dwóch płodozmianach z jego 20% i 33% udziałem. W laboratorium określono skład ilościowy zbiorowisk grzybów zasiedlających nasiona po 0,5-, 1,5- i 2,5-rocznym okresie przechowywania. Z nasion łubinu otrzymano ogółem 1077 kolonii grzybów. Do najliczniej izolowanych należały grzyby z rodzaju Penicillium - 29,3%, Alternaria alternata - 26,7 % i Rhizopus nigricans - 12,7% ogółu wyosobnień. Wśród grzybów patogenicznych dla łubinu dominował gatunek Colletotrichum gloeosporioides - 16,3%. Uprawa łubinu z jego 20% udziałem w płodozmianie ograniczała liczebność kolonii grzybów zasiedlających nasiona, w tym także patogenicznego gatunku C. gloeosporioides. Proces odkażania nasion zmniejszył ogólną liczbę kolonii grzybów izolowanych z nasion obydwu odmian, w tym głównie z rodzaju Penicillium oraz gatunku Rhizopus nigricans. Większą liczebność izolatów C. gleosporioides stwierdzono w kombinacji z nasionami odkażanymi. Odmiana Amulet charakteryzowała się bogatszym pod względem ilościowym zbiorowiskiem grzybów w porównaniu z odmianą Juno. Czas przechowywania miał wpływ na liczebność i skład gatunkowy grzybów izolowanych z nasion łubinu żółtego. Wraz z wydłużaniem się okresu przechowywania wzrastała liczebność grzybów z rodzaju Penicillium i Rhizopus, natomiast zdecydowanie malała grzyba C. gloeosporioides.
