Title: Relative resistance to Rice yellow mottle virus in rice
Abstract: We identified sources of Rice yellow mottle virus (RYMV) resistance in rice cultivars. Eight cultivars together with susceptible and resistant controls were evaluated under screenhouse conditions as inoculated and uninoculated treatment in completely randomised design with three replications. Seedlings were inoculated with the virus by sap transmission at two weeks after sowing. Disease incidence and severity (scale 1-9: 1-3 = green leaves with sparse dots or streaks, 9 = yellow or orange leaves and some plant dead), yield, and agronomic traits were recorded. Data analyses included Area Under the Disease Progress Curve (AUDPC), independent t-test, and Analysis of Variance. According to differences in most measured traits control cultivars FARO 29 and Gigante were proved to be the most susceptible and partially tolerant ones, respectively. Cvs FARO 12, FARO 17, FARO 37, and FARO 52 were classified as partially tolerant. Uninoculated control plants performed better than the inoculated for all the yield and agronomic parameters. Reduction in plant height (6%) and number of tillers per plant (4.8%), increased days to heading (3 days), and reduction in paddy yield (6.5%) was lowest in cv. Gigante. Paddy yield per plant of the RYMV-inoculated was the highest in cv. Gigante (2.4 g). The rice cultivars which combined RYMV-resistance with high-yield could be utilised in rice breeding programmes in order to enhance food security.

Title: Forecasting system for infection risk of phoma stem canker in selected regions of the Czech Republic in 2009-2011
Abstract: In the period 2009-2011 monitoring of the incidence of phoma stem canker was carried out at selected sites of the Czech Republic (Šumperk and Opava regions in North Moravia). The risk of infection was evaluated by assessing the autumn release of Leptosphaeria spp. ascospores and with the proPlant prediction model. In recent years, the incidence of phoma stem canker has been relatively low and this corresponded with the total count of ascospores released in the autumn period but not with an increased level of infection risk announced by the proPlant model. During the monitored period the ascospore concentration reached maximally 2 ascospores/1 m3 per day. Maximum ascospore release was recorded in 2010 as a result of favourable weather conditions. The first incidence of phoma leaf spot has been observed in mid-October. The higher values of ascospores concentration were recorded in the Opava region, but the total number of the trapped ascospores was more often higher in the Šumperk region.

Title: Evaluation of antifungal activity of sodium salts against onion basal rot caused by Fusarium oxysporum f.sp. cepae
Abstract: The efficacy of twelve sodium salts as possible alternatives to synthetic fungicides for the control of onion basal rot caused by Fusarium oxysporum f.sp. cepae was evaluated. In vitro tests showed that there were significant differences between the inhibitory effects of sodium salts on the mycelial growth (P ≤ 0.05) and 2% (w/v) concentrations of sodium metabisulfite and sodium fluoride completely inhibited mycelial growth of the fungus, while other salts did not. Sodium metabisulfite and sodium phosphate monobasic had lower pH values than the other salts. Unlike sodium metabisulfite, sodium phosphate monobasic could not decrease the mycelial growth. The ED50, minimum inhibition concentration (MIC), and minimum fungicidal concentration (MFC) values indicated that sodium metabisulfite was more inhibitory to the fungus compared to sodium fluoride. In soil tests, inhibitory effect of sodium metabisulfite on the fungus was higher than that of sodium fluoride, where sodium metabisulfite completely inhibited mycelial growth at even 0.4% concentration.

Title: Genetic variation of Chilo suppressalis Walker (Lepidoptera: Pyralidae) populations in Guilan and west of Mazandaran provinces analysed with RAPD markers
Abstract: Genetic variation of striped stem borer Chilo suppressalis populations in Guilan and Mazandaran provinces in Iran was studied in 2010 by means of RAPD markers. Collected 45 samples from 19 locations (representing 17 counties in Guilan province and 2 counties in Mazandaran province) were classified into four groups of populations: three population groups corresponding to the west, centre, and east of Guilan and one population group from the west of Mazandaran. RAPD PCR analysis showed that Chilo suppressalis populations in Mazandaran are genetically different from the Guilan populations while the western populations of Guilan are genetically separated from the two other populations. The central and the eastern populations of Guilan exhibit some similarities with those of Mazandaran and the similarities are more obvious between the eastern populations of Guilan and the western population of Mazandaran. The population from the centre of Guilan showed the highest level of intra-population genetic variation possibly due to wider rice cultivated area and/or due to higher sample size. The results showed a high level of genetic variation in Chilo suppressalis populations in the two provinces in Iran. In spite of the model species is a widely distributed pest, the study indicated that the samples originated in populations with a different genetic make-up.

Title: Effect of exogenous salicylic acid on some physiological parameters and alleviation of drought stress in Nigella sativa plant under hydroponic culture
Abstract: To study the effect of salicylic acid on photosynthetic pigments (chlorophyll a, b, total chlorophyll, and carotenoids), polyphenol compounds, anthocyanin, flavonoids, phenylalanine ammonia-lyase activity, malondialdehyde, lipoxygenase activity, electrolyte leakage, relative water content, soluble sugar contents, and protein content of black cumin (Nigella sativa) under drought stress in hydroponic culture, an experiment was conducted as a completely randomised design in a factorial arrangement with three replicates. Experimental treatments included salicylic acid at three levels (0, 5, and 10µM) and drought stress (induced by polyethylene glycol 6000) at four levels (0, -0.2, -0.4, and -0.6 MPa). Results showed that salicylic acid application through the root medium increased drought tolerance of black cumin seedlings. Plants pre-treated with salicylic acid exhibited slight injury symptoms whereas those not pre-treated with salicylic acid had moderate damage and lost considerable portions of their foliage. In conclusion, salicylic acid could protect the Nigella plant against drought stress through increasing of all the mentioned traits, and 10µM salicylic acid was the most effective level under both conditions.
