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 ...

Corrective Effect of Average Grain Size on Grain Boundary Number of ZnO Varistors
Key Engineering Materials, 2008The 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 ...

Natural variations in Multi‐Grain Spikelet 1 enhance grain number in sorghum
Journal of Integrative Plant BiologyA single recessive gene, Multi-Grain Spikelet 1 (MGS1), governs the multiple-grain spikelet trait in sorghum. The natural variants mgs19E and mgs1BA45 trigger adjacent double-pistil primordia, significantly boosting grain numbers per panicle, suggesting potential strategies for breeding high-yield sorghum.

Variability in Grain Number and Grain Weight and Sample Siz for their Estimation in Bengal Gram.
Madras Agricultural Journal, 1976Bengal gram was grown under three differont plent spacings (30 x 10 cm, 45: 10 cm and 30x20 cm) during 1973 Kharif season at Tamil Nadu Agricultural University experimental farm. At the time of harvest, 50 plants in the centre of each plot were selected at random and data on grain weight por plant and grain number per plant were collected.

‘Bedload’ dynamics: Grain impacts, momentum transfer and derivation of a grain froude number
Earth Surface Processes, 1979AbstractA test is proposed for Bagnold's postulate that the normal weight stress due to moving ‘bedload’ is balanced by a solid transmitted stress due to the rate of change of momentum produced by grain impacts on unit area of the stationary bed. The test involves derivation of an expression for normal momentum transfer due to saltating grains at ...
