A Quantitative Knowledge-based Model for Designing Suitable Growth Dynamics in Rice
Dry matter Expert system Knowledge-based model LAI Rice Stem number
2009/7/24
Quantifying growth dynamics in rice (Oryza sativa L.) is important for precision design and diagnosis in cultural management. The primary objective of this study was to develop a general knowledge-bas...
A Knowledge-Based Model for Nitrogen Management in Rice and Wheat
Grain yield Nitrogen fertilization model Nitrogen strategy Rice Wheat
2009/7/20
Excessive nitrogen fertilization results in low nitrogen-use efficiency. To improve nitrogen management for high yield and high nitrogen efficiency in rice and wheat, we developed a knowledge-based ni...
A Model to Estimate the Increase of Leaf Number on the Main Culm of the Rice Plant
Cool summer damage Developmental model Early warning system Effective accumulated air temperature Paddy rice
2009/7/16
We are building an early warning system for preventing the decrease in rice-yield by cool summer damage. To monitor the developmental stage of rice plants in the whole Tohoku area, we constructed a mo...
A New Morphogenetic Model on the Most Suitable Leaf-Internode Unit and Developmental Stage for Controlling Plant Types in Rice Cultivation
Controlling plant type Internode elongation Leaf elongation Lodging Nitrogen absorption
2009/7/15
In any theory on rice cultivation, methods for controlling the plant type form the core. An analysis identified the most suitable leaf-internode unit for targeting to control the plan type and the app...
Analysis of Root Growth Characteristics Based on a Pipe-model Theory and Distribution of Root Nodules in Soybean (Glycine max Merr.)
Pipe model Root Root nodule Soybean
2009/7/15
Based on the pipe-model theory, the root growth characteristics and root nodule distribution in soybean grown in pots were analyzed, using the variety Fukuyutaka and two mutants derived from the varie...
A Simple Model to Predict the Developmental Stages of Rice Panicles Using the Effective Accumulative Temperature(Modelling, Information Technology and Environment)
Cool summer damage Developmental model Early warning system Effective accumulated air temperature Kernel Paddy rice
2009/7/10
An early warning system for preventing the decrease in rice yield by cool summer damage in the whole Tohoku area is constructed. This needs to predict the developmental stages of rice plants from the ...
Model Analysis of the Determination of Leaf, Spikelet and Floret Primordium Number on Main Stem of Japanese Spring Type Wheat in the Southwestern Part of Japan
Wheat Floret Spikelet SEM Rate of initiation Model
2009/7/9
Primordium initiation on the main stem of field-grown Japanese spring type wheat was studied with a scanning electron microscope to quantify the process determining the number of leaves, spikelets an...
Estimation of Endodormancy Completion Stage and Bud Burst Stage in Forced Culture of Japanese Persimmon (Diospyros kaki Thunb.) ‘Tonewase’ by Developmental Rate Model
bud burst rate cuttings Developmental Index temperature
2009/7/9
We developed a Developmental Rate Model (DVR model) of Japanese persimmon (Diospyros kaki Thunb.), which was estimated by bud burst rate of cuttings chilled at constant temperatures (0, 5, 8, 11 and 1...
Statistical Analysis of the Development of Internal Browning in Japanese Radish in Relation to Thermal Condition Using Logit Model
air temperature covering materials soil temperature
2009/7/8
To clarify the correlation between the occurrence of internal browning (IB) in Raphanus root and the thermal condition, especially, during the later growth period, a logit model was established, using...
Application of a Model for Prediction of Mulberry Shoot Elongation to Various Regions
Mulberry Prediction model Shoot growth
2009/7/8
A model for prediction of shoot elongation was applied to various regions in Japan, and its fitness was evaluated. In the model, the shoot elongation rate in one arbitrary day was decided by the avera...
A Simple Method for Presumption of Bud Burst Stage in Forced Culture of Japanese Persimmon (Diospyros kaki Thunb.)‘Tonewase’by Developmental Rate Model
Developmental Index endodormancy completion stage heating days mean air temperature
2009/7/8
We developed a simple method for presumption of the bud break stage in forced culture of Japanese persimmon (Diospyros kaki Thunb.) ‘Tonewase’ by the Developmental Rate Model (DVR model). Developmenta...
USING RESIDUAL ANALYSIS TO VALIDATE RICE SOWING DATES EXPERIMENT MODEL
Sowing dates rice statistical model residual analysis
2010/3/26
Picking a model for a problem is a major undertaking. If the model fits well then it can be used to increase understanding of the problem and/or for prediction. Several statistical procedures have bee...
SIMULATIONS OF THEORETICAL ECOSYSTEM GROWTH MODEL (TEGM) DURING VARIOUS CLIMATE CONDITIONS
climate modelling ecosystem climate change theoretical ecological model
2010/3/26
Climate change has a great impact on the build and the work of natural ecosystems. Disappearance of some population or growth of the number in some species can be already caused by little change in te...
