Abstract:In model experiments in soil culture, the effect of different methods of treatment with sodium selenite on the photosynthetic activity of spring wheat variety Zlata was studied under extreme growing conditions. Under drought conditions, the inhibition of the growth of the photosynthetic surface of spring wheat plants was revealed. Under conditions of excessive water supply, a sharp decrease in the area of the assimilating surface of wheat plants was observed. The positive effect of sodium selenite solution on the photosynthetic activity of spring wheat plants was established with insufficient and excessive water supply to wheat plants.

Foliar Treatment

The purpose of the article was to study the resistance of spring wheat under the influence of foliar treatment of plants with silicate bacteria according to lipid peroxidation (LP) and yield. The studies were conducted on spring wheat (variety ‘MiS’). The cultivation technology is typical wheat in this agroclimatic zone. The foliar treatment was carried out with a culture of bacteria Bacillus oligonitrophilus by spraying at the rate of 0.5 l/m2 of bacteria suspension containing 109 cells/ml (equally to 100% concentration). Field experiment design: option 1 – plants without treatment (control); option 2 – treatment with B. oligonitrophilus fertilizers at the stage of tillering; option 3 – treatment with B. oligonitrophilus fertilizers at the stage of tillering/stem elongation; option 4 – treatment with B. oligonitrophilus at the stage of tillering/stem elongation/heading. The activity of LP in wheat leaves was identified according to the content of malondialdehyde (MDA). The content of MDA was determined photometrically during interaction with thiobarbiturate. Wheat yield increase was observed in options 3 and 4 (by 11 and 15%, respectively). The content of MDA decreased in all phases of wheat vegetation in the same experimental options (by 14 and 21%, respectively), which indicated the antioxidant effect of the studied preparation. Thus, the bacterization of wheat with B. oligonitrophilus leads to the plant resistance increase. The protective effect is probably due to the action of a complex of their biologically active substances (metabolites) including the antioxidant mechanism of action.

SUMMARYWheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety mixtures to varying levels of simulated and natural competition, as well as environmental stress at one conventionally and two organically managed locations in central Alberta, Canada, between 2003 and 2005. Three modern hard red spring wheat varieties (Superb, semi-dwarf; AC Intrepid, early maturing and 5600HR, tall), along with 13 two- and three-way variety mixtures, were planted under two levels of simulated weed (Brassica juncea L.) competition at each of the eight location-years. The B. juncea weed competition treatment decreased yields at all locations. Overall yield was lowest at the certified organic farm and highest under conventional management. Sole-crop semi-dwarf Superb and all three Superb–Intrepid mixture entries consistently yielded among the highest, regardless of management system, testing location or competition treatment. The 1:1 and 1:2 Superb–Intrepid mixture entries were the most stable of all entries tested. Early season vigour was strongly associated with yield, with the strongest correlation occurring under low-moisture, low-nutrient, high-competition conditions at the certified organic farm. Spring wheat variety mixtures may provide greater stability with little or no reduction in yield, while providing greater competitive ability.

The spring wheat variety Varyag whith high potential nitrogenase activity and the greater contents of chlorophyll in leaves and the active strain of the bacteria Azospirillum sp. 77, selected from the washed roots of the spring wheat variety Varyag, were used for creation of effective association “wheat – diasotrophs of genus Azospirillum”. Inoculation of wheat variety Varyag seeds with the bacterial suspension Azospirillum sp. 77 promoted the reliable increase of nitrogenase activity on roots of plants (by 46 %), content of chlorophyll in leaves (by 18 %) and structural parameters of wheat crop (weight of grain from 1 ear and weight of 1000 grains were increased as a result of inoculation by 16,5 and 16 % accordingly).

Positive Effect

An assessment of the phytotoxicity of natural (lime, zeolite and phosphorite) minerals and their nanostructured analogues (nanostructured lime, nanostructured water-zeolite suspension (NWZS), nanostructured water-phosphate suspension (NWPS) and a spine) has been carried out. a monocotyledonous test plant (spring wheat variety Ulyanovskaya-105) has a positive effect on all studied minerals. The length of the seedling among native minerals is stimulated by lime and phosphorite, among nanominerals - nanostructured lime and NWZS. All native minerals have a positive effect on biometric indicators, among nanostructural ones – nano-lime and NWPS. Seedling biomass is stimulated only by zeolite and NWZS. Thus, native zeolite has the best data on the length of the seedling (by 48.9 %), the length of the coleoptile (by 53.6 %) and the biomass of the seedling (by 16.1 %), and in NWZS - along the root length (by 12.8 %), root biomass (by 13.5 %) and seedling biomass (by 13.7 %). Thus, according to most indicators, the best are zeolite (among native ones) and NWZS (among nanostructured minerals).

Spring Wheat Variety

During 1997–1998, the reaction of the collections of winter and spring wheat varieties to Tilletia caries was determined. In both years the most diseased winter varieties were Simona and Sparta, the least diseased were Samara and Ilona. High variability in the level of infection was observed in some varieties (VIada, Estica, Regina, Vega). No winter wheat variety was completely resistant. The most diseased spring wheat variety was Alexandria in both years, while Grandur showed no infection. High variability in the level of infection was observed in the special trials with cv. Ina and Contra. In trials of the efficacy of seed dressing against T. caries and T. laevis there was variability only in the controls, but not in dressed variants.
