Chemical composition of the essential oils of Schinus molle leaves and resins, collected from East Mediterranean region of Turkey were identified by gas chromatography/mass spectrometry (GC/MS) and phytotoxic effects of the oils at different concentrations (0.5, 1.0, 2.0, 4.0 and 8.0 μl/ml) were investi- gated on Portulaca oleracea L. and Raphanus raphanistrum subsp. sativus (L.) Domin. At the highest concentration, it was found that the essential oil of S. molle leaves and resins inhibited at rates of 57%, 67% and 70%, 80% the seed germination of purslane and radish, respectively, when compared to the control. Also, S. molle leaves essential oil at the same concentration decreased Radicle length (RL) and Plumule lengths (PL) of purslane and radish in the rates of 82.94, 78.09% and 94.36, 81.30%, while RL and PL of both plants tested were inhibited in the rates of 78.03, 68.99% and 88.91, 76.95% by S. molle resins essential oil. This study is the first report on P. oleracea L. and R. raphanistrum subsp. sativus (L.) Domin about phytotoxic effects of the essential oils of Schinus molle leaves and resins

This study was conducted to determine the inheritance of common bunt resistance in twelve bread wheat varieties and their half-diallel hybrids in Turkey. The disease ratings were performed on the F2 generations of the hybrids in field conditions. The obtained data were analysed by the χ2 test to determine the effective gene numbers and inheritance type in the disease resistance. In addition, the data were evaluated according to the Jinks-Hayman diallel analyses. In conclusion, it was found that of the twelve wheat parents, four contained three resistance genes and four of them contain two resistance genes. The dominant genes were prominent in the population and complete dominance was present. Therefore, the selection for disease resistance should be delayed until the following generations.

Subcritical water extraction of Tribulus terrestris leaves and fruits was performed at 100 ºC and 60 atm for 30 min. Chemical composition of volatile extracts was investigated. A simple lactone compound Loliolide (23,82%) was main components associated with 26 identified molecules which are mostly oxygenated compounds.
