山东农业大学生物化学英文课件Section M- Nitrogen metabolism。
Strawberry (Fragaria ananassa Duch.) plants cv. Selva was grown in soilless culture under greenhouse conditions to present the effects of application of supplementary calcium combined with nutrient so...
Effects of planting density on nitrogen fixation activity (acetylene reduction activity, ARA), yield and yield components of soybeans (Glycine max (L.) Merr.) were evaluated in the field experiment c...
Measurement of Ammonium Nitrogen Volatilization Retes from Rice Leaves during the Ripening Period.
Two-rowed low-protein barley Daikei HC-15, which is related to low-protein cultivar Karl, was studied to determine the changes in the percentage of nitrogen in the grain, leaf and stem during ripening...
The amounts of nitrogen fixed in Crotalaria juncea and C.pallida were evaluated by the 15N-isotope dilution technique and the difference method using Zea mays in pot experiments.The effects of incorpo...
Nitrogen topdressing and leaf removal were carried out on the rice variety Hitomebore immediately after heading and on Akitakomachi before heading, respectively.In the nitrogen topdressing(+N)plot, c...
Specific characteristics in the photosynthetic response to nitrogen application were compare between Oryza glaberrima Stend. strains introduced from West Africa and O. sativa L. strains including japo...
The nitrogen uptake and yielding ability of non-nodulating soybean genotype (En1282) were investigated under field conditions. Dried cattle feces were applied at levels ranged from 192 to 960 kg N/ha ...
The α-amino nitrogen (A-N) contained in the roots and crowns of sugar beet is one of the harmful non-sugars that deteriorate the quality of sugar beet roots. This research was conducted to investigate...
Soil nitrogen mineralization and nitrogen absorptions by rice in paddy-upland rotational fields (rice-wheat-soybean) were studied in the Nara basin for four years (2000-2003) in comparison with those ...
The change of nitrogen (N) uptake after topdressing was estimated from the N concentration in bleeding sap and bleeding rate of the sap in a lowland rice variety, Koshihikari, grown in a pot and in th...
The root-system development of two rice varieties, Koshihikari and Kichinkurogome, fertilized with ammonium nitrogen was compared with that of these varieties fertilized with nitrate nitrogen. In both...
The object of the study was the grain of winter barley harvested at the beginning of its setting, milk maturity, dough maturity and full grain maturity stages at nitrogen fertilization doses of 0, 60,...
The aim of the study was to compare the festulolium suitability in mixtures with meadow clover. The first factor was the share of red clover (40, 60 and 80%), the second factor was the level of nitrog...
