Catechol is an allelochemical which belongs to phenolic compounds synthesized in plants. Its herbicidal effects on weed species; field poppy (Papaver rhoeas), creeping thistle (Cirsium arvense), henbit (Lamium amplexicaule) and wild mustard (Sinapis arvensis) were investigated using wheat (Triticum vulgare) and barley (Hordeum vulgare) species as control plants. In comparison to 2,4-D (a common...

Chloroplast DNA (cpDNA) diversity was found within and among populations (245 accessions total) of wild barley, Hordeum vulgare L. ssp. spontaneum Koch from Israel and Iran. Three polymorphic restriction sites (HindIII, EcoRI, BclI) which define three distinct cpDNA lineages were detected. One lineage is common to populations in the Hule Valley and Kinneret of northern Israel, and in Iran. The ...

Remains of barley (Hordeum vulgare) grains found at archaeological sites in the Fertile Crescent indicate that about 10,000 years ago the crop was domesticated there from its wild relative Hordeum spontaneum. The domestication history of barley is revisited based on the assumptions that DNA markers effectively measure genetic distances and that wild populations are genetically different and the...

Bu çalışmada fiğ ( Vicia sativa L.), nohut Cicer arietinum L.) ve arpa Hordeum vulgare gelişimi üzerine etkilerini belirlemek amacıyla, bazı Şanlıurfa Baraj Göllerinde yoğun olarak bulunan Microcystis viridis Aphanizomenon gracile’ in karışık kültürünün farklı dozlarının etkisi araştırılmıştır. Siyanobakteri karışımından hazırlanan dozlar, topraklara püskürtülerek uygulanmıştır. Kök uzunluğu ba...
