Detection of Arbuscular Mycorrhizal Fungi Within Colonised Roots of the Gramineae Family Members by Nested-Polymerase Chain Reaction (Pcr)
(2011) Demir, S.; Sipahioglu, H.M.; Kaya, I.; Usta, M.; Savur, O.B.
In this study, it is aimed to asses the association of arbuscular mycorrhizal (AM) fungi within colonised rhizosphere of Gramineae family members through a survey by using nested polymerase chain reaction method in Van province (Turkey). From 24 agro-ecological fields, a total of 82 samples belonging to Gramineae family were tested by molecular methods. The presence of Glomus intraradices and Glomus mosseae was ascertained in 10 plants belonging to eight different species by using fungus specific primers. Root colonisation ranged from 6 to 37% within rhizosphere of Gramineae family members and the average root colonisation by AM fungi was 22%. © 2011 Copyright Taylor and Francis Group, LLC.

Some Important Plants Belonging To Lamiaceae Family Used in Folkloric Medicine in Savur (mardin/Turkey) Area and Their Application Areas
(Centenary University, 2016) Arasan, S.; Kaya, I.
This study aimed to determine the purpose and the mode of use of some important plants belonging to Lamiaceae family used in folk medicine in Savur (Mardin). Surveys were carried out in Savur Town Centre, and in some towns and villages of Savur district, during the years of 2012-2013. A total of 207 resource persons were interviewed. A total of 96 species belonging to 43 families were determined that these plants are used for therapeutic purposes. Rosaceae 10 (9.6 %), Asteraceae 8 (8.6 %), Lamiaceae 6 (5.7 %), Cucurbitaceae 6 (5.7 %), Solanaceae 4 (3.8 %), Malvaceae 4 (3.8 %) and Fabaceae 4 (3.8 %), has been identified major first 7 families in the research area. The plants belonging to Lamiaceae family are very used in folkloric medicine. Therefore this family has emphasized in this study. As a result of the study, 6 species belonging to Lamiaceae families were determined which have been used for therapeutic purposes. The plants were determined in research area were; Cyclotrichium leucotrichum (Stapf.) Leb., Mentha longifolia L. Hudson subsp. typhoides (Briq.) Harley var. typhoides (L.) Hudson, Mentha x piperita L., Salvia multicaulis Vahl, Teucrium polium L., Thymbra sintenisii Bornm & Aznav subsp. sintenisii Bornm. et. Aznav. Local names and the mode of use and necessary doses of therapeutic plants were documented. © 2016, Centenary University. All rights reserved.
Studies on Effects of Russian Knapweed (Acroptilon Repens (L.) Dc) and Butter Cup (Ranunculus Damascenus Boiss and Gaill), Causing Problem in Winter Wheat, on Yield and Determination of Their Economical Thresholds in Van
(TUBITAK, 1999) Kaya, I.; Tepe, I.
In this study, effects of different densities of Russian knapweed (Acroptilon repens (L.) DC) and butter cup (Ranunculus damascenus Boiss and Gaill) on yield and yield components of winter wheat were researched in Van. It was determinated that, increasing densities of A. repens have decreased number of spike, grain, straw and total yield of wheat. But, increasing densities of R. damascenus have not been effective on yield and yield components because of being small constitution and having short growing period. Ten plants per m2 of A. repens reduced grain and straw yields respectively 24.3 and 19%. These amounts are over economical threshold, therefore weed cotrol must be done. When the densities were 60 plants/m2, loss of grain yield was about 50% and loss of straw yield was about 40%.
