    Diseases of Larix genera tree were studied in the forests of Lithuania in 2009-2013. L. decidua and L. polonica could be considered as perspective species to be grown in Lithuanian forests. Acclimatization of L. laricina, L. sibirica and L. leptolepis is restricted by pathogens and pests, edaphic and climatic conditios. The most dangerous pathogen of Laria spp. in Lithuanian forests is Lachnellula willkommii.

    Alotriploidinių ir alotetraploidinių lelijų Lilium tarprūšinių hibridų palikuonių citogenetinė analizė

    Atlikus palikuonių, kilusių iš keturių skirtingos kilmės alotriploidinių ir vienos alotertaploidinės lelijų veislės, citogenetinę analizę paaiškėjo, kad ir alotriploidų, ir alopotetraploidų gyvybingos kiaušialąstės gali turėti tiek subalansuotus haploidinius (n = x = 12) arba diploidinius (2n = 2x = 24) chromosomų rinkinius, tiek tokius, kuriuose yra daugiau negu viena papildoma chromosoma. Dalis alopoliploidinių motinų palikuonių buvo diploidiniai apomiktai, atsiradę iš neapvaisintų kiaušialąsčių. Tik alotetraploidinė veislė ‘Lesly Woodrif ’, turinti tris Vamzdinių (T) ir vieną Rytinių hibridų (O) genomus (TTTO), formavo vaisingas haploidines žiedadulkes.

    Aplinkos sąlygų poveikis C apykaitai agroekosistemose
    [Impact of environmental conditions on carbon cycle in maize (Zea mays L.) and rapeseed (Brassica napus L.) agroecosystems]

    The aim of this research was to calculate and compare the carbon (C) budget of agroecosystems, identifying seasonal respiratory soil carbon dioxide (CO2) (Ra+h) and assimilated photosynthetic CO2 at different growth stages. The research was carried out for maize (Zea mays L.) and rapeseed (Brassica napus L.) agroecosystems during the vegetation period (June - September, 2014) at the PI ASU Training Farm. The mean soil CO2 emissions were 1.971 ± 0,12 μmol m-2s-1 for maize, and 2.199 ± 0.25 μmol m-2s-1 for rapeseed. The highest measured soil CO2 emissions were 2.432 ± 0.23 μmol m-2s-1 for rapeseed in June, and 2.963 ± 0.28 μmol m-2s-1 for maize in the second part of July. The mean C budget in maize agroecosystems was 15.54 t ha-1, while it was 10.30 t ha-1 in rapeseed.

    Ruginio vikio (Vicia villosa Roth) radavietės Lietuvoje
    [Locations of hairy vetch (Vicia villosa Roth) in Lithuania]
    research article
    Vytauto Didžiojo universiteto Botanikos sodo raštai = Scripta horti botanici universitatis Vytauti Magni. Kaunas, Vilnius : Vytauto Didžiojo universitetas; Versus aureus leidykla, T. 19 (2015), p. 60-65
    Hairy vetch (Vicia villosa L.) is an archeophyte in Lithuania. It is thought that it reached the country’s territory with seeds of cereal. According to the data of Flora of SSR (1971), hairy vetch is a rather rare plant in Lithuania. It is a valuable forage crop, used as fodder and soil cover plant for weed control in many countries. In crop phytocoenoses it grows like a weed. In order to estimatethe prevalence of hairy vetch in Lithuania, herbarium samples data of Botanical institute and expedition data of „Genepool“ project were used. Assessment of herbarium samples (year 1933–2000) was performed and 93 hairy vetch locations in 27 different administrative districts were found. According to these data, a map of prevalence of Vicia villosa was made. The distribution of hairy vetch in territory of Lithuania is unequal. Mostly, hairy vetch was found in eastern, southern, south-eastern Lithuania. Majority of locations were found in Alytus (10 locations), Varėna (9), Prienai (8) and Trakai (7) districts. Only some sporadic locations were found in the central, northern and north-western parts of Lithuania. V. villosa was not found in northern Lithuania – Kupiškis, Pakruojis, Radviliškis, Šiauliai, Akmenė, Joniškis and Mažeikiai districts.
