    Seed germination rate in lentil (lens culinaris) with chalky spotted
    (Parlar Scientific Publications, 2017) Bicer B.T.; Toncer O.; Kavak H.; Akinci C.
    The chalky spot syndrome is a serious seed-quality problem in red lentil in the southeast Anatolia of Turkey. This research was carried out to determine the chalky spot rate and its effect on the seed germination in twenty lentil genotypes. Germination tests as three groups performed; (i) seeds from damaged location were cleaned, and two groups were divided as damaged and non-damaged, (ii) all seeds from damaged location, and (iii) seeds from non-damaged location. Chalky spot rate among genotypes ranged from 11.0 to 42.92%. Mean of germination speed in damaged seeds was 46.88%, and ranged from 20 to 66% in damaged seeds. Mean of germination speed in non-damaged seeds was 84.5%. Chalky spotted seed rate strongly reduced germination rate. © by PSP.

    Some biological parameters in Sordaria Fimicola
    (2012) Kavak H.
    Biological parameters associated with identification, isolation, proliferation, resistance and discharge of asci and ascosporous were investigated on Sordaria fimicola. As unusual habitats, the fungus was isolated from surfaces of necrotized leaf spots of Hordeum vulgare, H. spontaneum and Datura inoxia at various rates in the vegetation period of 2009 in the Şanli{dotless}urfa district, Turkey. Treatments were conducted at different temperatures and nutrition media. Together with mycelium development, the most perithecial production was observed on Potato Dextrose Agar-1 at 25°C in shortest time. At the same temperature, the slowest mycelium growth and perithecial production was observed on Potato Dextrose Agar-2. In absence of glucose in Corn Meal Agar, perithecial production and mycelium development was also fast. Mycelia tufts of fungus were resistant to different degrees or doses of ethyl alcohol. On the mycelium appendages stored in the ethyl alcohol, the perithecium of the fungus produced. Globe, turbinate, obpyriform and clavate were respective steps in the formation of perithecium. Together with asci, ascosporous were actively thrown from bursting perithecial opening in the matured perithecium. It is considered that this fungus species may occupy the necrotized areas on living plant leaves as an alternative habitat.
