In the conditions of Primorye krai, the Fagopyrum esculentum Moench cultivars of different ecological and geographical origin were studied in terms of their productivity and fruit biochemical composition. The cultivar Bashkirskaya krasnostebelnaya was found to be of interest for the purposes of breeding buckwheat for higher content of flavonoids: it exceeds the reference cultivar Izumrud by 7.5 mg/100 g. The cultivar Demetra is richer in essential amino acid content (arginine, lysine, phenylalanine, leucine, isoleucine, valine, and tryptophane) in its fruits. The studied cultivars had more potassium (1.41–1.49) than phosphorus (0.54–0.55) in their fruits. As a result, the promising cultivars were selected as follows: the indeterminate ones—Zemlyachka, Inzerskaya, and Bashkirskaya krasnostebelnaya; the determinant ones—Demetra and Dikul with a high content of flavonoids, protein, fat, and essential amino acids in their fruits. Using the adaptability parameters, we identified the determinant cultivars Dikul and Dialogue as highly adaptable and stable; their average productivity reached 1.5 t ha–1 and exceeded the reference cultivar by 5–18%. 相似文献

The aim of this study was to determine the accumulation of antioxidants at аn early stage of development of organs of P. incarnata L. plants grown in greenhouses (medicinal aromatic plants were used for comparison), as well as to evaluate the effect of biostimulant Albit. The use of amperometric and biochemical methods made it possible to measure and evaluate the total antioxidant content in aqueous extracts of leaves of aromatic plants with sedative effects compared to aqueous extracts of P. incarnata L. leaves. The latter are characterized by a lower level of antioxidant accumulation. Seed treatment with biostimulant Albit and foliar treatment of aerial parts of the P. incarnata L. plant increased the total antioxidant content and the content of carotenoids, chlorophylls a and b, and the yield of aerial parts of the plant by 10–15%. The findings suggest that the P. incarnata L. plants grown in greenhouses can be used to create antioxidant herbal remedies. 相似文献

The present studies have shown Laurus nobilis L. to be a drought tolerant species. When the plant was first subjected to dehydration, the rate of net photosynthesis decreased from Pn = (8–10) to –1 μmol/(m2 s) and to –3 μmol/(m2 s) during the second dehydration before it was subsequently irrigated. The rewatering on August 5 and August 8 promoted a sharp burst of this parameter, but the Pn value was restored to its original level only after August 8. Soil drought caused a drop in a rate of transpiration from 65–70 to 10 mg/(m2 s). Watering soil up to a 15% moisture level brought an increase in E = 25 mg/(m2 s), but only the second watering managed to fully restore it to the initial value. Apical growth of the plants was closely correlated with soil moisture. As the soil moisture was reduced to W = 15–5%, the terminal growth reached a saturation point and started to plateau. Watering the soil up to W = 15% promoted apical growth by 4 mm. Reducing soil moisture to W = 3–4% caused a complete cessation of the growth. Subsequent watering to W = 27–28% led to a gradual and complete recovery of turgor and an increase in the growth rate up to 6–8 mm per day. The surface response functions Pn = f(I, W) and E = f(I, W) allowed us to determine conditions and levels of potential maximums and boundaries of the areas of optimum photosynthesis and transpiration: optimum Pn = 8–9 μmol/(m2 s) with I = 900–1400 μmol/(m2 s) and W = 17–24% and the optimum E = 25–35 mg/(m2 s) with I = 1000–1400 μmol/(m2 s) and W = 16–24%. 相似文献

Water chest nut Trapa is a minor fruit crop and potential carbon sequester of atmospheric carbon. Mass production of water chest nut using a vast number of unused small water bodies and derelict waters is a win-win-win-win strategy toward mitigation of global warming, nutritional security, empowerment and resource utilization. Growth performance of Trapa was conducted in small culture units using different CNP ratios (25:02:01; 101:08:01; 290:01:01) at a fixed dose (0.2 kg/tank) of mixed manure with different doses (100, 200, 400, 600 g) of optimal CNP ratio (101:08:01) during the life cycle of Trapa. The total number of fruits and the wet weight of Trapa in different dose treatments ranged from 56 to 192 and from 258 to 379 g/tank. Yield of Trapa remained maximum when CNP ratio was 101:8:1 at 200 g/tank and the dosage was 200 g/tank with the optimal CNP ratio (134 g) and then declined with further rise in fertilizer dose. The proximate analysis of Trapa revealed the highest phosphorus content in all the tissues (fruit, leaf, and root) of Trapa grown in the CNP ratio of 101:08:01. Of the total amount of carbon in Trapa, contribution was maximum by the fruit (38–41%), followed by leaf (27–35%) and root (23–32%) in different ratio treatment. The C content of harvested Trapa grown in different CNP ratios (Table 4) was higher in fruit (38–41%) followed by leaf (27–35%) and root (23–32%) among tissues. The amount of C observed in control (32%) increased by 6% in 25:02:01 (34%) which was higher than remaining two treatments (31%). Dry weight or total carbon content of water chestnut tended to rise with increasing levels of phosphate of water from the dosage of 100 to 200 g with optimal CNP ratio and declined thereafter. A direct relationship between the dry weight or carbon content of Trapa and the total carbon content or phosphate to total carbon ratio of water was established. However, the carbon content remained between 27–32% in all the three tissues of Trapa culture when cultured in different dose treatments. It is reasonable to conclude that water chestnut may be promoted for mass cultivation using the recommended culture protocol that would help trapping atmospheric carbon, provide nutritional security and employment generation and resource utilization. 相似文献

The results are obtained by simultaneous diagnostics of mutant CV- and BL-alleles. Five groups of animals–carriers and noncarriers of mutations are identified. In Russia the mutant CV-alleles are met more frequently because of the intensive use of their carriers. While elimination of BL-allele was started earlier due to developed methods, the diagnostics of CV-mutations has been undertaken later. Propagation of missense-mutations in the world and the Russian Federation has been occurring through the breeding bulls and cows–carriers. Initially spermobanks and, afterwards, cows were reserves for the diagnosed BLand CV-mutations. 相似文献

The ionic composition of the of the intracellular content of the alcohol yeast Saccharomyces cerevisiae R. 1039 biomass was studied for confirmation of their use perspectiveness as a mediator to enable the management the mineral content of food in the manufacture of food and feed additives. The ionic composition of the obtained extracts were identified using the method of capillary electrophoresis. It is found that the quantitative ion content in the cell extracts depends on the concentration of the nutrient medium. When the yeast S. cerevisiae R. 1039 was cultivated on the medium with the soluble solids concentration of 30%, the intracellular ion content in the extracts was 1.3 times higher than when the yeast was cultivated on 12% wort by increasing the concentration of chlorides, sulfates, formates, potassium ions, and calcium. The yield of the yeast S. cerevisiae R. 1039 biomass increased 1.6 times per unit of volume of the medium with increase of the soluble solids concentrations from 12% to 30%. 相似文献

The aim of the experimental study is to analyse the consequence of carbon dioxide elevation on activity of nitrate reductase (NR; EC 1.6.6.1), nitrite reductase (NiR; EC 1.7.7.1), glutamate synthetase (GOGAT; EC 1.4.1.13) in leguminous Cyamopsis tetragonoloba leaves. Plants were exposed to different atmospheric carbon dioxide concentrations 300 ppm (ambient) and 490 ppm (an elevated) conditions. A decrease in activity of Nitrate Reductase (NR), Nitrite Reductase (NiR), Glutamate Synthetase (GOGAT) was found in elevated condition when compared to ambient condition. Plant nitrogen on dry weight basis was found to decrease under elevation with no significant change in soil nitrogen. Soil pH was found to change significantly under elevation, thus showing a decline in pH and promoting soil acidiosis. Total plant fresh weight (FW) and total plant dry weight (DW), Leaf area/cm2 were found increased in elevated condition. Thus, in Cyamopsis tetragonoloba plant it can be concluded that under carbon dioxide elevation Nitrate reductase, Nitrite reductase and Glutamate synthetase activity is suppressed due to a reduced amount of nitrate translocation and NADH availability for reduction in plant which is correlated with reduction in plant total nitrogen content where as plant growth and biomass is enhanced due to higher carbon fixation. 相似文献
