Genetic and Molecular Factors Determining Grain Weight in Rice
rice grain weight grain size regulatory mechanisms molecular biotechnology
2023/4/21
Grain weight is one of the major factors determining single plant yield production of rice and other cereal crops. Research has begun to reveal the regulatory mechanisms underlying grain weight as wel...
Pollination dynamics, grain weight and grain cell number within the inflorescence and spikelet in oat and wheat
Cell Number Distal Grain Filling Potential Floret
2013/3/4
Oat (Avena sativa L.) and wheat (Triticum aestivum L.) vary in the structure of their inflores-cences and also in how pollination proceeds within the inflorescence. In both species the grain position ...
Seed size effect on grain weight and agronomic performance of tef [Eragrostis tef (Zucc.) Trotter]
Eragrostis tef seed size tef tef agronomy
2010/9/10
Tef [Eragrostis tef (Zucc.) Trotter], the indigenous Ethiopian cereal, has a very minute seed size, yet it has a strong bearing both on the preferences of farmers for planting material and consumers a...
稻谷千粒质量近红外光谱定量分析（Determination of 1000-grain Weight of Paddy Using NIRS Technique）
稻谷 千粒质量 近红外光谱
2009/8/11
利用近红外漫反射光谱分析技术对稻谷千粒质量进行了测定和研究。通过对70个不同品种的稻谷样本进行近红外光谱扫描，将获得的光谱进行10种不同方法的预处理，然后应用PLS方法建立稻谷千粒质量预测的定标模型，根据交互验证决定系数（R2）和交互验证标准差（RMSECV）进行最佳定标模型选择，最后依据稻谷千粒质量预测值与真实值间的相关系数（r）和预测标准误差（SEP）进行模型预测能力评价。结果显示，在光谱区间...

2009/7/28
The same seedlings of three rice cultivars were transplanted into both paddy fields, experimental fields of Tottori University (Koyama) and skillful farmer's field (Hojo), and given their respective ...
Daytime and Nighttime Field Spectral Imagery of Ripening Paddy Rice for Determining Leaf Greenness and 1000-Grain Weight
Artificial light source Digital image Reflectance Rice SPAD 1000-grain weight
2009/7/21
A spectral-image observation technique to measure the reflectance information of rice plant organs (instead of the overall canopy) under either daylight or artificial light at night was developed, and...
Effect of Ethephon on the Harvest Index and Grain Weight of Hokkaido-Bred Wheat Cultivar "Haruyutaka" Grown in a Warm Area of Western Japan
Culm length Ethephon Grain filling Harvest index Reserve material Translocation Triticum aestivum L
2009/7/10
A wheat cultivar "Haruyutaka" bred in Hokkaido has a small harvest index, grain weight and yield when it grows in Yamaguchi, Japan. Ethephon, a growth regulator, applied to the surface of wheat canopy...
Harvest Index and Grain Weight Decline when Wheat Cultivar "Haruyutaka" Bred in Hokkaido Grows in the Warm Areas of Western Japan
Crop growth rate Grain weight Haruyutaka Harvest index Triticum aestivum L
2009/7/10
A wheat cultivar, "Haruyutaka", bred in Hokkaido, was planted and examined at nine cultivation conditions of the four seasons, 1995/1996 to 1998/1999, in Yamaguchi, Japan, for the purpose of introduci...
Cultivation on a High Ridge Bed did not Increase the Grain Weight of Hokkaido-Bred Wheat Cultivar “Haruyutaka” in a Warm District of Western Japan
Ridge bed height treatment Overluxuriant growth Crop growth rate Triticum aestivum L
2009/7/9
Wheat cultivars, Haruyutaka and Daichinominori, were planted on high and low ridge beds to investigate the influence of water logging on the grain weight. Grain yield, dry matter production, canopy ...
Correlation of Palatability Properties with Grain-weight and Thickness of Rice Grain—Case of cv. Koshihikari cultivated in Ibaraki prefecture in 2005
1000-grain weight Amylose content Brown rice thickness Koshihikari Milled rice
2009/7/7
We investigated some palatability properties of Ibaraki rice cv. Koshihikari, specifically examining the correlation of palatability with grain weight and thickness. We investigated the rice from 20 ...
