The effect of different technological conditions on forage yield, growth behavior and competition ability of ryegrass, red clover and their mixture was analyzed. The results showed that red clover makes better use of the nutrition space in the case of variants sown in mixture with Italian ryegrass than in the monoculture, independent of the density of the plants or fertilization regime. The highest DM production was obtained at the mixture formed by red clover and Italian ryegrass on the variants sown on 12.5 cm distance between rows, the increase of the nutrition space being directly proportional to the decrease of the DM production in the case of this forage mixture.

Competition Ability

The development of logistics is strongly correlated to the comprehensive economy development. Logistics plays the key role of correlating the other nine main economic industries, and transporting goods and service within the domestic and international markets. It is strongly demanded that the adjustment and revitalization of logistics industry shall satisfy the logistics industry upgrade itself, and increase the competition ability of other economic sections, so as to provide stable, high-efficient business running environments for the other industries as well. It is of great strategic meaning for the adjustment, restructuring and upgrading of the national economic system, thus comprehensively strengthening the national competition ability. The State Council of China has made a series of revitalization plans for the logistics industry, which has been integrated into development plan of the macroeconomic system.

The aim of the research was to evaluate the competition capacity and find suitable proportion of different types of Festuca rubra and Deschampsia caespitosa in grass mixtures for decorative lawns. A field experiment with Deschampsia caespitosa cv. Kometa in monoculture or in mixtures with Festuca rubra L. varieties Viktorka (ssp. trichophylla), Barborka (ssp. commutata) and Petruna (ssp. rubra) was established in Větrov in 2007. The sowing rate was 40 000 viable seeds per m<sup>2</sup> (0, 25, 50 or 75% of F. rubra). The sward was mown at 3 cm. The number and weight of tillers of the turf components were evaluated during three years. The highest number of tillers (on average 63.3 thousand/m<sup>2</sup>) and weight of the dry aboveground phytomass (on average 196 g/m<sup>2</sup>) were found with F. rubra ssp. trichophylla. Its particular tillers had the lowest dry weight (0.32 g/100 tillers). The lowest number of tillers (32.9 thousand/m<sup>2</sup>) and low weight of dry aboveground phytomass (134 g/m<sup>2</sup>) showed mixtures with F. rubra ssp. rubra, whose tiller weight was relatively high (0.42 g/100 tillers). The size of F. rubra tillers was not influenced either by the mixture composition or by vegetation years. The number of F. rubra tillers was not significantly different in the third and first vegetation year. The number of D. caespitosa tillers in monoculture decreased during the years from 45 to 30 thousand/m<sup>2</sup>, but the weight of dry aboveground phytomass increased significantly from 233 g/m<sup>2</sup> to 318 g/m<sup>2</sup>. Poor competition of D. caespitosa was found in the mixture with F. rubra ssp. commutata (on average 4% of total number of tillers and 7% of the total weight of the dry aboveground phytomass). F. rubra ssp. trichophylla was less competitive and the least competition with D. caespitosa was found in F. rubra ssp. rubra, After three years the proportion of D. caespitosa in mixtures with F. rubra ssp. rubra significantly increased to 36% of the total number of tillers and to 55% of the total weight of phytomass. Mixtures of D. caespitosa and F. rubra ssp. rubra were found to be promising for low input lawns.

Resistant Genotypes

Chickpea (Cicer arietinum L.) production in the Canadian prairies is challenging due to a lack of effective weed management mainly because of poor competition ability of the crop and limited registered herbicide options. Chickpea genotype with resistance to imidazolinone (IMI) herbicides has been identified. A point mutation in the acetohydroxyacid synthase1 (AHAS1) gene at C581 to T581, resulting in an amino acid substitution from Ala194 to Val194 (position 205, standardized to arabidopsis), confers the resistance to imazamox in chickpea. However, the molecular mechanism leading to the resistance is not fully understood. In many plant species, contrasting transcription levels of AHAS gene has been implicated in the resistant and susceptible genotypes in response to IMI. The objectives of this research were to compare the AHAS gene expression and AHAS enzyme activity in resistant and susceptible chickpea cultivars in response to imazamox herbicide treatment. Results from RT–qPCR indicated that there is no significant change in the transcript levels of AHAS1 between the susceptible and the resistant genotypes in response to imazamox treatment. Protein hydrophobic cluster analysis, protein-ligand docking analysis, and AHAS enzyme activity assay all indicated that the resistance to imazamox in chickpea is due to the alteration of interaction of the AHAS1 enzyme with the imazamox herbicide.
