This study was conducted in order to determine plant characteristics and seed yields of some local faba bean (Vicia faba L.) populations in comparison with registered faba bean cultivars/lines between 2003 and 2005 in Samsun. Totally 15 genotypes, three faba bean cultivars (Eresen-87, Filiz-99 and Lara), two lines (FLIP85-172FB and FLIP86-116FB) from ICARDA, 10 local populations collected from some districts and villages of Samsun, Amasya, Sinop and Tokat provinces, were used in the study. Seed yield ranged from 1654.3 to 3914.8 kg/ha and from 2779.9 to 5892.3 kg/ha in 2003-2004 and 2004-2005 growth season, respectively. On average of two years, the highest and the lowest seed yields were obtained from Eresen-87 (4790.2 kg/ha) and G14 population (2217.1 kg/ha), respectively. G3, G4, G5, G6 ve G7 populations were among the first ten high yielding genotypes, which were not statistically different from each other. G3 was in the second rank for seed yield (3950.9 kg/ha) among all faba bean genotypes. Although plants produced more vegetative parts in the first year, biological yieds were lower in the first year than in the second year. High seed yields had an important role in high biological yields determinated in the second year.

In this study, a fungicide namely Equation Pro (22.5 % Famoxadone + 30 % Cymoxanil) was pulverized on tomato (Lycopersicon esculentum Mill.) in greenhouse under pot conditions. Then the likely effects of this fungicide on stomata of plants were examined. Applications of Equation Pro were carried out as recommended dose (40 g/ 100 L water) as given on the label and two fold higher (80 g/ 100 L water) doses. In conclusion, fungicide applications resulted in decreasing in stomata index compared to untreated plants. The results of width-length measurements related to stoma were found generally higher at the upper surface of leaves as compared to untreated group, while these values were decreased at the underside of leaves. An increase in the numbers of abnormal and closed stomata were observed with paralel to increasing in application dose. This may indirectly cause a negative effect in the amount of the yield.

Analysis of the Zooplankton Community by the Shannon - Weaver Index in Kesikköprü Dam Lake, Turkey
(English)

Sibel YİĞIT
Ankara University, Faculty of Science, Department of Biology, Ankara-Turkey

Kesikköprü Dam Lake that is oligotrophic is represented by 11 Rotifera, nine Cladocera and eight Copepoda species. The data obtained from the zooplankton community in Kesikköprü Dam Lake were analysed by the Shannon - Weaver index. The index values showed no positive correlation with the total number of zooplanktonic organisms. Therefore, the index value (H= 2.10) is higher in autumn than in other seasons. The abundance data and Shannon - Weaver index values were both analysed by UPGM clustering method. Winter and summer seasons were found to be the most similar by using Shannon - Weaver index values, but spring and autumn showed similarity with seasonal abundance. In this respect, the Shannon - Weaver index is not useful for monitoring and determining the trophic status of Kesikköprü Dam Lake. However, H values express seasonal homogeneity in the species abundance of zooplankton community.

Key Words: Zooplankton, Shannon - Weaver, abundance, Turkey
