Drought Effect on Grain Number and Grain Weight at Spike and Spikelet Level in Six-Row Spring Barley
Journal of Agronomy and Crop Science, 2010Water is the primary regulator of yield formation in cereals. The effect of water limitation and its timing on development of yield components were studied in detail at spike and spikelet level in spring barley (Hordeum vulgare L.). An experiment with three watering treatments (control watering, CONT; drought prior to pollination, DR1 and terminal ...

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.

Grain Emergency Transport Model on Unascertained Number
Applied Mechanics and Materials, 2010The 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.

‘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 ...

Improved modeling of grain number in winter wheat
Field Crops Research, 2012Abstract Four models were compared for estimating grain number per square meter (GPSM) of winter wheat (Triticum aestivum L.). As a data-base for model comparison, values of GPSM were determined in a field trial in northern Germany ranging from 8.3 to 25 thousand grains per square meter under the influence of three years (2003/04 to 2005/06), five ...

The effects of radiation and nitrogen on number of grains in wheat
The Journal of Agricultural Science, 1995SUMMARYThe possible interacting effects of shading and N supply on number of grains ofTriticum aestivumL. (cv. Buck Ñandú) were investigated at Balcarce, Argentina, during the 1988/89 and 1989/90 growing seasons. Shading was imposed fromc.13 days before anthesis to 6 days after, and four rates of N fertilization were supplied within each shading ...

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.

The effect of varying the number of pollen grains used in fertilization
Theoretical and Applied Genetics, 1978The number of pollen grains placed upon a stigma influence both the development of pollen tubes and subsequently the progeny which result from fertilizations by gametes from these pollen tubes. The first influence is demonstrated by reduced pollen tube growth rates when pollen grains are few in number.
