The results showed that in the experimental plots,there were 16 weed species belonging to 10 family and 16 genera,occupying about 34% of the total number of weed species in winter wheat fields in Shaanxi Province.
Three common wheat varieties Longjian 127, Shan 160 and Jinmai 47 were transformed by pollen tube pathway. The results of kanamycin resistant selection, PCR and PCR Southern test showed that transgenic plants for all the three varieties were gained.
The results demonstrated that Shannong 87074 551 was an alien disomic substitution line between common wheat and E. elongatum, with chromosome number of 2 n =42, and its chromosome configurations was 21Ⅱ.
Etiolated wheat coleptiles were inhibited 100 and 40%, respectively, at 10-3 and 10-4 M.
The results showed that there were significantly positive linear relationships between the inhibitory rates of wheat seed germination and root elongation and the CODcr of the mother liquor scraps.
The toxicity of MSG wastewater to the test crops was in the order of tomato >amp;gt; Chinese cabbage >amp;gt; wheat, indicating that tomato was the most sensitive to the wastewater, and could be considered as an ideal toxic bioindicator.
The initial stage of amino acid metabolism was intensified in germinating wheat seeds with exogenous glutamine and proline.
The strain formed extracellular phenol oxidases during surface growth on a liquid medium in the presence of guayacol and copper sulfate, as well as during submerged cultivation in liquid medium containing wheat bran and sugar beet pulp.
Change in Lectin Specificity of Winter Wheat Seedlings in the Course of Infection with Mycoplasms
The activity of soluble lectins in leaves and roots of seedlings of winter wheat (Triticum aestivum L.) cultivar Mironovskaya 808 increased 1 day and 2 days, respectively, after infection with the mycoplasma Acholeplasma laidlawii 118.
Response of Winter Wheat to Cold: Production of Phenolic Compounds and L-Phenylalanine Ammonia Lyase Activity
The formation of soluble and polymeric (lignin) phenolic compounds, activity of L-phenylalanine ammonia lyase (PAL, EC 220.127.116.11), and content of free L-phenylalanine during cold hardening of winter wheat plants (Triticum aestivum L.) were studied.
The effect of Furolan on the physiological and biochemical characteristics of ripening winter wheat grain
Cytogenetic Analysis of Hybrids Resistant to Yellow Rust and Powdery Mildew Obtained by Crossing Common Wheat (Triticum aestivum
The karyotypes of 47 hybrid lines obtained from crosses of common wheat Triticum aestivum L.
The introgression of alien genetic material to the common wheat genome was realized via substitutions of complete A+-,G-, and D-genome chromosomes, chromosome arms, or their fragments.
Allele Distribution at Locus WMS261Marking the Dwarfing Gene Rht8in Common Wheat Cultivars of Southern Ukraine
PCR screening of common wheat cultivars produced in the southern Ukraine showed the prevalence of a 192-bp allele at locus WMS261that indicates adaptive significance of a corresponding allele of the Rht8gene in the southern regions.
These results illustrate the similarity of phenol metabolism in leaves of winter and spring wheat cultivars.
Protein markers of plant traits in breeding spring wheat for grain yield and quality
Intranuclear supramolecular mechanisms for induction of growth morphogenesis in mature embryos of winter and spring wheat
Vegetative experiments showed that the population density of antiphytopathogenic bacillar species introduced into the rhizosphere of spring wheat seedlings essentially depended on the soil temperature and not on the soil moisture content.
The adsorption dynamics of the parent Sp245 and mutant KM252 strains of azospirilla on the seedling roots of the soft spring wheat cv.
