The subject of this study is 2-year variability research (2007 and 2008) of the chemical composition of naturally dried biomass samples of 3 different sorghum species, which are widely used in the sou...
Studies on the Response of Nodulated Soybean to Nitrogen Fertilizer:II. On the seed quality and assimilate partitioning to seeds at different nodal position
Glycine max Nitrogen nutrition Nitrogen fertilizer Seed oil Seed protein
2009/8/5
A glasshouse pot sand culture experiment was conducted to determine the effects of three levels of combined nitrogen-0N (0), 1N (100), 2N (200 pm) -on nitrogen nutrition, seed protein and oil content ...
Plant Growth, Uptake and Partitioning of Nitrogen in Alfalfa Seedlings as Affected by the Form of 15N-Labelled Combined Nitrogen
Alfalfa Ammonium-N Nitrate-N Nitrogen fertilizer Nitrogen uptake and partitioning Recovery of 15N Root growth
2009/7/30
We investigated the growth, uptake and partitioning of nitrogen (N) in alfalfa seedlings grown in the pot soil where 15N-labelled combined N was applied as nitrate-N or ammonium-N by means of basal dr...
Carbon and Nitrogen Dynamics with Aging in Seminal Root System of Rice Seedling
Aging Carbon Lateral roots Nitrogen Partitioning
2009/7/29
The allocation pattern of carbon (C) and nitrogen (N) with aging among several organs of rice seedling was investigated with particular attention to the difference in seminal root axis (SRA) and conco...
Grain Filling Mechanisms in Spring Wheat:VI. Cultivar variation in nitrogen metabolism and changes in assimilate shortages
Grain filling phases Nitrogen metabolism Nitrogen percentage in grain Shading treatment Spring wheat varieties
2009/7/27
Improvement of wheat flour quality, an increase in grain nitrogen content accompanied by an increase in grain yield, is required through cultivation techniques and breeding program. Changes in nitroge...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-Leaf Blades by Leaf Position on the Stems of Rice Plants:II. Uneven translocation of nitrogen between outside and inside half-leaves
Chlorophyll meter value Distribution Half-leaf blade Leaf blade width Nodal root Translocation
2009/7/27
We have reported in a previous paper that the outside half-leaf had a smaller volume and deeper leaf color than the inside half-leaf. The half-leaf color was not dependent only on the difference in le...
Characteristics of Nodulation and Nitrogen Fixation in the Improved Supernodulating Soybean (Glycine max L. Merr.) Cultivar ‘Sakukei 4’
Glycine max L.Merr. Growth Nitrogen fixation Root nodule Soybean Supernodulation
2009/7/24
Supernodulating soybean lines have more than several times as many nodules as normal cultivars. They are expected to have high nitrogen-fixing ability and enhanced productivity, but their yields have...
Growth Respiration in Rice Organs as Affected by Nitrogen Content
Growth coefficient Growth respiration Nitrogen content Rice
2009/7/23
The relationship between growth respiration and nitrogen content in rice organs was investigated. Top and root CO2 exchange rates were continuously measured for 5-6 days under different nutrient conce...
