Wheat floret survival as related to pre-anthesis spike growth
(Oxford University Press, 2011-10)
Further improvements to wheat yield potential will be essential to meet future food demand. As yield is related to the number of fertile florets and grains, an understanding of the basis of their generation is instrumental ...
Photoperiod-sensitivity genes shape floret development in wheat
(Oxford University Press, 2019-02)
Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ...
Nitrogen and radiation effects during the active spike-growth phase on floret development and biomass partitioning in 2- and 6-rowed barley isolines
(Csiro Publishing, 2010-10)
The paramount importance of accumulated biomass in active-growing spikes over the number of grains per unit area has been well documented. However, it is not clear how different nitrogen (N) and radiation supplies during ...
The physiology and genetics behind fruiting efficiency: A promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-05)
Fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination and the ...
More fertile florets and grains per spike can be achieved at higher temperature in wheat lines with high spike biomass and sugar content at booting
(Csiro Publishing, 2014-01)
An understanding of processes regulating wheat floret and grain number at higher temperatures is required to better exploit genetic variation. In this study we tested the hypothesis that at higher temperatures, a reduction ...
A comprehensive study of spike fruiting efficiency in wheat
(Crop Science Society of America, 2020-05)
Spike fruiting efficiency (FE), defined as grains per unit of spike dry weight at anthesis (SDWa) is a promising trait for improving grain number (GN) in wheat (Triticum aestivum L.). It is often estimated at maturity as ...
Physiological traits associated with reductions in grain number in wheat and barley under waterlogging
(Springer, 2018-08)
Aims Negative effects of waterlogging on wheat and barley yield are expressed mainly through reductions in grain number per plant. Physiological traits associated with reductions in grain number of wheat and barley plants ...
Identification and validation of QTL for spike fertile floret and fruiting efficiencies in hexaploid wheat (Triticum aestivum L.)
(Springer, 2020-06)
The spike fruiting efficiency (FE—grains per unit spike dry weight at anthesis, GN/SDW) is a promising trait to improve wheat yield potential. It depends on fertile floret efficiency (fertile florets per unit SDW—FFE, ...
