Abiotic stress and control of grain number in cereals

Plant Science, 2011
Grain number is the only yield component that is directly associated with increased grain yield in important cereal crops like wheat. Historical yield studies show that increases in grain yield are always accompanied by an increase in grain number. Adverse weather conditions can cause severe fluctuations in grain yield and substantial yield losses in ...

Determination of grain number in sorghum

Field Crops Research, 2008
Grain number is an important component of grain yield in sorghum. Research in wheat and maize has indicated a dependency of grain number on the crop or panicle growth rate around anthesis (CGRa and PGRa respectively), but little quantitative information is available for sorghum.

Moderate Salinity Stress Reduces Rice Grain Yield by Influencing Expression of Grain Number- and Grain Filling-Associated Genes

Journal of Plant Growth Regulation, 2020
Soil salinity is an environmental stress severely impacting on rice grain yield. However, limited information is available on how salinity affects expression levels of genes determining grain yield. In this study, we investigated agronomic traits associated with grain yield among three japonica rice cultivars grown either under moderate salinity with ...

Wheat yields: Doubling-up on grain numbers

Nature Plants, 2015
Modulating the expression of two flowering-genes can be used to produce wheat spikes with modified spikelet arrangement and higher grain number.

Genetic and molecular basis of grain size and grain number and its relevance to grain productivity in higher plants

Genome, 2006
Grain size and grain number constitute 2 important components of grain yield. In particular, the grain size also influences the end-use quality (e.g., flour yield and protein content) and attracts consumer preference. These 2 traits are also the components of the domestication syndrome of crop plants.

The average number of grain boundaries per grain in a polycrystal

Acta Metallurgica, 1986
Abstract Using the unit operations that produce arbitrary topological transformations in a 4-connected space-filling structure of trivalent convex polyhedra it is shown that the average number of faces, F , in the individual cells (grain boundaries in isolated grains) cannot be smaller than eight.

Corrective Effect of Average Grain Size on Grain Boundary Number of ZnO Varistors

Key Engineering Materials, 2008
The average intercept length and related corrective method are proposed to calculate the average grain boundary number. The average value of barrier voltage by direct measurement to single grain boundary is 3.3V in literatures, but from our prepared ZnO varistor samples, the value of the average barrier voltage by the average grain size is only 2.3 V ...

The wall-associated kinase GWN1 controls grain weight and grain number in rice

Theoretical and Applied Genetics
Grain size is a crucial agronomic trait that determines grain weight and final yield. Although several genes have been reported to regulate grain size in rice (Oryza sativa), the function of Wall-Associated Kinase family genes affecting grain size is still largely unknown.

Optimizing Size and Number of Grain Bins

Applied Engineering in Agriculture, 1990
A mathematical model was developed to predict the optimum bin diameter, bin height, and number of bins based on user inputs of total storage volume, interest rate, unit cost of electricity, airflow rate, and annual number of hours of airflow. The grain storage system was divided into several cost components including land rent, site preparation, bins ...

Grain Emergency Transport Model on Unascertained Number

Applied Mechanics and Materials, 2010
The question to choose a grain supplement emergency path is uncertain. By using uncertain methods, integration of experts can be done. Base on the uncertain theory, we build the model of choosing a path with minimum risk in the process of grain emergency transportation and the algorithm.
