Counting grain mounts; number percentage vs. number frequency

Journal of Sedimentary Research, 1969
ABSTRACT Quantitative mineralogical analysis of grain mounts results in either a number percentage or a number frequency. The number percentage is obtained when all the grains on the slide or all the grains in representative portions of the slide are counted. The number percentage is solely a function of the numerical abundance of the mineral grains in

Natural variations in Multi‐Grain Spikelet 1 enhance grain number in sorghum

Journal of Integrative Plant Biology
A 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.

A genetic playground for enhancing grain number in cereals

Trends in Plant Science, 2012
Improving 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.

‘Bedload’ dynamics: Grain impacts, momentum transfer and derivation of a grain froude number

Earth Surface Processes, 1979
AbstractA 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 ...
