Determination of grain number in sorghum
Field Crops Research, 2008Grain 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.

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.

Abiotic stress and control of grain number in cereals
Plant Science, 2011Grain 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 ...

The average number of grain boundaries per grain in a polycrystal
Acta Metallurgica, 1986Abstract 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.

A genetic playground for enhancing grain number in cereals
Trends in Plant Science, 2012Improving the yield stability of cereal crops with a view to bolstering global food security is an important priority. The components of final grain number per plant at harvest are determined by fertile spikes per plant, number of fertile spikelets per spike and number of grains per spikelet.

Grain weight response to increases in number of grains in wheat in a Mediterranean area
Field Crops Research, 2006Abstract This study explored whether the average grain weight of wheat tends to be reduced when grain number is increased due to either competition or, to a consistent increase in the relative proportion of grains of smaller weight potential. Three field experiments considering environmental, genetic and environmental × genetic effects on yield and ...

The wall-associated kinase GWN1 controls grain weight and grain number in rice
Theoretical and Applied GeneticsGrain 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.

Field Crops Research, 1994
Abstract Past breeding programs for increased wheat grain yield have increased the number of grains per m 2 , associated with a higher spike dry weight at anthesis. Other workers have shown that shading during the preanthesis period strongly reduced the number of grains per m 2 of the crop via reductions in the spike dry weight at anthesis. However,

Optimizing Size and Number of Grain Bins
Applied Engineering in Agriculture, 1990A 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 ...
