Effects of Top Dressing on Growth and Panicle Dry Weight as Affected by Soil Water Stress at the Early Panicle-Development Stage in Rice (Oryza sativa L.)
Leaf area duration Net assimilation rate Rice SPAD Total dry weight
2010/3/4
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
Sterile Spikelets of Rice Plants Induced by Low Temperature in 1988:Difference in heading date among stems and spikelet locations on the panicle
Heading date Main stem Rice plants Spikelet locations on the panicle Sterility Susceptibility to low temperature
2009/8/6
A large number of sterile spikelets were induced by low-temperature at the booting stage of rice plants during the middle to the end of July in 1988. The authors investigated various aspects of occur...
Developmental Change in Panicle Water Potential in Rice
Leaf water potential Panicle water potential Rice
2009/8/4
Rice panicles start to transpire just after heading. We can therefore expect that the water potential of panicles changes little prior to heading and varies in response to transpiration after heading...
Effects of Panicle Water Potential on Water Stress Susceptibility in Rice
Development Panicle Rice Water potential Water stress susceptibility Winnowed paddy number
2009/7/30
The effects of drought on the rice yield differ depending on the time when plants are subjected to the drought. It is therefore probable that water stress susceptibility, the degree of yield reduction...
Effect of Sodium Chloride on the Panicle and Spikelet Morphogenesis in Rice:II. Developmental morphology of the panicle
Degenerated rachilet Developmental morphology Environmental stress Glume Panicle
2009/7/29
To provide new information on salt stress in rice plant based on developmental morphology, structural changes of panicle and spikelet were investigated. As the salt concentration increased, growth and...
Modelling and Prediction of Developmental Process in Rice:II. A model for simulating panicle development based on daily photoperiod and temperature
Development Developmental index Developmental rate Heading date Model Panicle development
2009/7/28
Under the hypothesis that environmental responses of ontogenetic development of rice are different before and after panicle initiation (PI), a model for simulating rice panicle development and heading...
Activities of Enzymes for Sucrose-Starch Conversion in Developing Endosperm of Rice and Their Association with Grain Filling in Extra-Heavy Panicle Types
ADPglucose pyrophosphorylase Developing endosperm Extra-heavy panicle type Grain filling Inferior spikelet Rice Sink activity Sucrose synthase
2009/7/23
Rice cultivars with numerous spikelets per panicle (extra-heavy panicle types) frequently fail to exhibit their high yield potential due to low grain filling. Existing genetic variation in grain filli...
Does Regional Temperature Difference before the Panicle Initiation Affect the Tolerance for Low Temperature-Induced Sterility in Rice?

2009/7/23
The effects of elevated carbon dioxide concentration ([CO2]) on silica deposition on husk epidermis of rice (Oryza sativa L. cv. Akitakomachi) during the flowering stage were investigated in this stud...
Estimation of Young Panicle Length and Cool Injury of Rice Using Cumulative Temperature (Paper>Modelling, Information Technology and Environment)
Accumulated temperature Cool injury Developmental stage Prediction Rice Young panicle length
2009/7/14
The method of estimating the developmental stage necessary to prevent and analyze the cool damage in rice plants using meteorological elements was examined. We investigated the relationship between th...
