In this research, the effects of faba bean (Vicia faba L.) used for green manure and forage production as a winter catch crop on some soil biological properties were investigated. The field experiments were conducted in Çar- şamba Plain located in the north region of Turkey. The "green manuring-maize-wheat" crop rotation with a randomized complete block with four replications was repeated in two separate years. The treatments used to in-vestigate the management effect on soil enzyme activity were: (GM1-GM4) burying the whole above ground faba bean plant as green manure, (GM5-GM8) burying the under ground-stubbles of plants and (C1-C2) control. Different nitrogen doses of 0, 60, 120, 180 kg N ha-1 for maize, and 0, 50, 100 andl50 kg N ha-1 for wheat were applied following the green manuring. The results revealed that both types of green manure applications provided an increase in urease and dehydrogenase contents of soils compared to the control. The urease (UA) and dehydrogenase (DH) activities were higher with above ground parts of faba been application when compared to application of the underground stubbles. The activity of the UA and DG were significantly (P<0.05) influenced at the end of the maize harvest in the GM amended soils. At the end of the maize harvest, significantly (P<0.05) highest UA activity (205.1 μg N 1-1 g dry soil) was observed in the GM1 treatment compared to the control soil. While, the lowest UA activity was recorded in the GM5 (178.4 ng N 1-1 g dry soil). © by PSP. Source

We investigated the phylogenetic relationships in Tulipa in Turkey using DNA sequences from the plastid trnL-trnF region and the internal transcribed spacer (ITS) of nuclear ribosomal DNA. We generated trnL-trnF and nuclear ITS sequences for 11 Tulipa spp. from Turkey and compared the utility of trnL-trnF and ITS sequences for phylogenetic analysis. Neighbor-joining, Bayesian and maximum parsimony methods were implemented using the same matrices. Our study of Tulipa based on molecular data revealed congruent results with previous studies. Despite the relatively lower resolution of trnL-trnF than that of ITS, both sequence matrices generated similar results. Three clades were clearly distinguished, corresponding to subgenera Tulipa, Eriostemones and Orithyia. It is not fully resolved whether Clusianae should be recognized as a separate section of subgenus Tulipa or a distinct subgenus.© 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 172, 270-279. © 2013 The Linnean Society of London.

In this study, improvement of pole fresh bean populations gathered from the Middle Black Sea Region was attempted using pure-line selection method under greenhouse conditions. The aim was to regain the populations that have lost their distinctive typical properties through breeding and bring them into use of local farmers. Fresh pole bean populations collected from Çarşamba Plain of Middle-Black Sea region in 2003 were evaluated in terms of their agricultural characteristics under greenhouse conditions. In 2006 observation gardens were established in greenhouses; pre-yield and yield experiments were performed in the following 3 years (2007-2009). Eleven lines were selected according to UPOV criteria. In addition to best phenological and morphological traits being presented by Ç4-3, TK9-4 and TK43-4 lines in comparison to the control varieties; Ç4-3, TK43-4, L4 and TK50-3 lines outperformed the control varieties in terms of yield following stage I and stage II regional yield experiments on 11 lines between 2010-2011, and certain lines were selected to be candidates for certification.

In this study, single line (pure-line) selection method was applied on local populations of dwarf fresh beans with the characteristics of Aysekadi{dotless}n type which were collected from Çarsamba, Terme, Tekkeköy towns of Çarsamba plain and Ladik region in 2003. Observantion gardens were set up in 2005 and consecutively pre-yield, local yield and regional yield tests were conducted in the years starting 2005 to 2009. In these lines, phenological observations and morphological measurements were determined in accordance to UPOV criteria and rates of their yields were examined. As a result of all assesments, 7 lines (KO, TK15, T26, Ç31, TK7, TK1 and T23) were approved to comfort with our purpose, selected as candidates for registration and were also examined for resistance to anthracnose disease by means of STS and SCAR molecular markers closely linked to anthracnose resistance Co- genes. While, resistance gene loci markers for Co-2, Co-4, Co-4 2 genes were present in all of the 7 lines, Co-1 gene locus marker was observed in only one of the line (KO) and 5 lines were positive for the marker of Co-6/co-8 gene loci. Two of the lines T26 and TK15 were registered under the variety names of "Karabacak" and "Zeynebim" respectively and given certification for production permits in 2009. Source
