Sunulan bu çalışmada, XRF spektrometresi kullanılarak dört aromatik bitki taksonunun (Teucrium chamaedrys L. subsp. sinuatum, Astragalus kurdicus var. muschianus, Ranunculus arvensis ve Juglans regia) bazı soğurma parametreleri (kütle azaltma katsayıları, molar yok-olma etkin atom numaraları elektron yoğunlukları) 13.92 ile 59.54 keV foton enerji aralıklarında ölçülmüştür. Ölçümler Si(Li) detek...

abstract in this experiment the effects of two type of medium cultures, gibberellic acid and dark/cold and light/warm culture conditions on mature embryos germination of a local cultivar of walnut were investigated. the mature fruits were collected at 22 weeks postanthesis and after disinfection the mature embryo along with cotyledon pieces were excised and then were cultured on mt and modified...

The expressed sequence tag (EST) database represents a potentially valuable resource for the development of simple sequence repeat (SSR) markers for use in evolutionary studies. EST-SSRs reveal polymorphisms not only within the source taxon, but in related taxa as well. In this paper, we describe a case study in which the publicly available walnut (Juglans regia) EST database was used to develo...

INTRODUCTION Staphylococcus epidermidis is one of the most frequent causes of biofilm-associated infections on indwelling medical devices. With the emergence of methicillin-resistant S. epidermidis (MRSE), there is an urgent need to discover novel active agents against a range of Gram-positive pathogens. We screened the clinical isolates of S. epidermidis for susceptibility/resistance against c...

Walnut oil is a high-value product. Investigation of the variation and main climatic factors affecting oil’s chemical composition vital for breeding quality improvement. Therefore, fatty acid, micronutrients, secondary metabolites compositions contents in walnut were determined three species: Juglans regia L. (common walnut), J. sigillata Dode (iron their hybrids (Juglans × L.), which cultivate...

embryo culture were used to produce inter specific walnut hybrid plants between juglans nigra l. and j. regia l. developed ovaries were collected from j. rejia female flowers which were pollinated with j. nigra pollen grain by high dusting on a mature tree. in order to isolate embryos, exocarps were aseptically removed. isolated embryos from ovules at different developmental stages were transfe...

Phylogenetic analyses of extant species of Juglans (Juglandaceae) with the New and Old World distributions were performed using five cpDNA intergenic spacer (IGS) sequences (trnT-trnF, psbA-trnH, atpB-rbcL, trnV-16S rRNA, and trnS-trnfM) to elucidate the origin, diversification, historical biogeography, and evolutionary relationships within the genus. Overall, 3848 characters were sampled, yiel...
