Auxin is a phytohormone essential for plant development. However, our understanding of auxin-regulated endosperm development remains limited. Here, we described rice YUCCA (YUC) flavin-containing mono...
Water Status and Grain Production of Several Japonica Rices under Grain-filling Stage Drought
Drought Dryland rice Grain-tilling stage Leaf water potential
2009/8/6
This study was designed to compare leaf water potential (LWP) and grain yield responses to drought imposed during the grain-filling stage in several Japonica dryland (upland) and wetland (paddy) rice...
Effects of Ear Removal on Photosynthesis of the Flag Leaf during Grain Filling in Wheat
CO2 fixation system Ear removal Photochemical system Photosynthesis Ribulose-1
2009/8/5
In order to clarify the response of crops to sink restriction, we examined the effects of ear removal on photosynthesis of the flag leaf in wheat. For 11 days there was no difference in CO2 exchange r...
Grain Filling Mechanisms in Spring Wheat:I. Grain filling phases according to the development of plant organs
Assimilate Culm elongation Culm storage Grain filling phase Grain growth Photosynthesis Spring wheat Water soluble sugar content
2009/8/4
To define the growth phases for analyzing the physiological and morphological mechanisms of grain filling in a spring wheat canopy, the dry weight of the grains and the water soluble sugar content (WS...
Grain Filling in Rice Subjected to Drought at Three Stages
Drought Grain filling Imperfect rice kernel Rice Water stress Winnowed paddy
2009/8/4
The effects of water stress on the grain growth of rice appear to depend on the stages of plant development. The plants which were subjected to water stress during the grain-filling period produced mo...
Effects of Pre-Flowering Soil Moisture Deficits on Dry Matter Production and Ecophysiological Characteristics in Soybean Plants under Drought Conditions during Grain Filling
Dry matter production Photosynthesis Root system development Senescence
2009/7/31
Summer crop plants grown in rain-fed fields suffer from drought during a hot and relatively dry summer after the rainy season called "Baiu" in Japan. Since crop plants might develop vigorous shoots wi...
Grain Filling Mechanisms in Spring Wheat:III. Effects of shadings on dry matter accumulation in grain and culm
Dry matter accumulation rate Dry matter partitioning Grain filling phase Regression analysis
2009/7/30
To determine the effects of assimilate shortage to grain filling mechanisms in spring wheat canopy (cv. Haruyutaka), we examined the accumulation and translocation of dry matter in grain, along with w...
Grain Filling Mechanisms in Spring Wheat : II. Growth, accumulation and translocation in the daytime and at night during the four grain filling phases
Daytime and night time Grain filling phase Quantitative assessment of growth Regression analysis Spring wheat
2009/7/30
The dry weights and water soluble sugar contents (WSC) in grain, ear, culm and leaves of the field grown spring wheat (cv. Haruyutaka) were measured every morning and evening throughout the grain fill...
Effect of Brassinolide Applied at the Meiosis and Flowering Stages on the Levels of Endogenous Plant Hormones during Grain-Filling in Rice Plant (Oryza sativa L.)
Abscisic acid(ABA) Brassinolide(BL) Ethylene Indoleacetic acid(IAA) Low temperature(L-temp) Milk-ripe stage Panicle Rice
2009/7/29
Brassinolide (BL), a brassinosteroid, applied to rice plants in pots promotes panicle ripening. In this study, we examined the effect of BL applied at the meiosis and flowering stages on endogenous le...
Filling Percentage of Rice Spikelets as Affected by Availability of Non-Structural Carbohydrates at the Initial Phase of Grain Filling
Grain filling Initial growth of grain Non-structural carbohydrate Rice (Oryza sativa L.) Sink ability Sink source ratio
2009/7/27
The observed reaccumulation of non-structural carbohydrates (NSC) in culm and leaf sheath in the later half of the grain filling period, in spite of the existence of imperfectly filled rice spikelets,...
