On Resistance to Water Transport from Roots to the Leaves at the Different Positions on a Stem in Rice Plants
Ageing Lower leaf Midday stomatal closure Resistance to water transport Rice plants
2009/8/4
The degree of the midday depression in the stomatal conductance and the photosynthetic rate is larger in the lower leaves than in the upper leaves on a stem. It was clarified in the previous report th...
Regulation of Internodal Elongation of Rice Seedlings by Plant Growth Regulators
Brassinolide Deepwater rice Gibberellin Growth regulation Growth regulators Internode elongation
2009/8/4
We investigated the role of each plant hormone in the internodal elongation of rice seedlings using japonica rice cultivar 'Sasanishiki', and deepwater rice cultivar 'Leb Mue Nahng 111, and 'Habiganj ...
Effect of the High Nitrogen Treatment Prior to Transplanting on the Growth and Yield in Rice
Dry matter productivity Growth analysis Leaf blade morphology Nitrogen content Rice
2009/8/4
The effect of temporally high N application was investigated to develop the fertilization method that increases N content per leaf area (NCLA) without the increasing of specific leaf area. The change ...

The Changes of Endogenous Abscisic Acid in Developing Grain of Two Rice Cultivars with Different Grain Size
Abscisic acid Endogenous content Grain-filling process Grain size Rice
2009/8/4
Two cultivars of rice (Oryza sativa L.) with different grain size were investigated to measure the free ABA contents during grain development. In both cultivars, the content and concentration of endog...
Cultivar Difference in the Response of Root System to Nitrogen Application in Rice Plant
Adaptability Heavy manuring Nitrogen application Rice Root system
2009/8/4
This study was conducted to examine whether the root system development in rice plant under different nitrogen (N) application regimes is related to adaptability for heavy manuring (AHM) of the cultiv...
Response of the Seminal Root Elongation to NH4-Nitrogen in Several Rice Cultivars
Adaptability Heavy manuring NH4-nitrogen Rice Root elongation Seminal root
