This study was conducted to investigate the frost status in the 11 commercial cultivars, three newly introduced cultivars and two genotypes of olives. After the occurrence of frost at the Tarom region of Zanjan province in February 2019, three trees from each cultivar were selected. Frost symptoms were recorded based on observational indices. Gas exchange traits (stomatal conductance, transpira...

Cadmium (Cd) is one of the toxic heavy metals which can be absorbed by plants and have detrimental effects on plant growth and nutrients uptake. In order to investigate the effect of Cd on some vegetative growth parameters, nitrogen (N), phosphorus (P) and Cd uptake in aerial parts of seven rice cultivars, a pot experiment with three soil-applied Cd levels (0, 45, and 90 mg Cd/kg soil) and seve...

Combining both kinds of fuzzy logic forms including fuzzy T-S model and adaptive fuzzy logic systems, this paper presents an adaptive control scheme for a class of nonlinear systems. Firstly, the fuzzy T-S model is used to approximate the nonlinear systems, and the fuzzy control law of the fuzzy model is derived by the linear matrix inequality. Secondly, the adaptive fuzzy logic systems are con...

DNA based molecular markers allow precise, objective and rapid cultivar identification. In this study, five ISSR and two sets of fluorescence-labeled TP-M13-SSR markers were applied for discrimination of eight closely related wheat cultivars. Five ISSR primers revealed a total of 43 distinct reproducible bands, 29 (67.44%) of the 43 bands were polymorphic. The number of polymorphic bands detect...

Soybean cultivars from maturity groups III-V were grown in Heterodera glycines-infested locations in northeastern and southeastern Kansas from 1991 through 1994. Yield performance and nematode reproduction were significantly (P <0.01) affected by host response to H. glycines and year, whereas effects of cultivars within host response categories and cultivar x year interactions were generally ne...

Argentinean Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making. In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabern...

Several abiotic and biotic stresses can affect soybean in a growing season. Heterodera glycines, soybean cyst nematode, reduces yield of soybean more than any other pathogen in the United States. Field and greenhouse studies were conducted to determine whether preemergence and postemergence herbicides modified the reproduction of H. glycines, and to determine the effects of possible interactive...

A factorial experiment in hydroponic conditions was conducted to evaluate the activity of antioxidant enzymes, membrane stability and Na concentration in seedling of some rice cultivars, in 2014 summer in Ramin Agriculture and Natural Resources University of Khuzestan. Experimental factors were included salinity levels of NaCl (0, 4 and 8 ds.m-1) and rice cultivars (Amol3, Daniel, Shafagh, Fajr...

Panax ginseng has been cultivated for centuries, and nine commercial cultivars have been registered in Korea. However, these nine elite cultivars are grown in less than 10% of ginseng fields, and there is no clear authentication system for each cultivar even though their values are higher than those of local landraces. Here, we have developed 19 microsatellite markers using expressed gene seque...

Guo D.-L., Zhang Q., Zhang G.-H. (2013): Characterization of grape cultivars from China using microsatellite markers. Czech J. Genet. Plant Breed., 49: 164–170. A total of 32 different grape cultivars including representatives of local Chinese cultivars, some important and widely grown Chinese cultivars and international reference cultivars were genotyped at nine microsatellite loci in order to...
