Abstract Further improvements in wheat yields are critical, for which increases grain number would be required. In the recent past, higher was achieved through increased growth of juvenile spikes before anthesis, due to reduction stem growth. As current cultivars have already an optimum height, alternatives must identified further increasing number. One them is fruiting efficiency (grains set per unit spike dry weight at anthesis). Fruiting final outcome fate floret development and...
Wheat yield depends on the number of grains per square metre, which in turn is related to fertile florets at anthesis. The dynamics floret generation/degeneration were studied contrasting conditions nitrogen (N) and water availability modern, well-adapted, durum wheats order understand further bases for grain determination. Experiments carried out during 2008–2009 2009–2010 growing seasons Lleida (NE Spain). first experiment involved four cultivars (Claudio, Donduro, Simeto, Vitron) two N...
In Mediterranean durum wheat production, nitrogen (N) fertilization may be important to stabilize and increase yields. Wheat yield responses N are usually related grains per m2, which in turn is the consequence of processes floret development (floret initiation followed by death/survival) during stem elongation. The literature rather scarce terms relevance developmental dynamics, determining final number general particular regarding responsiveness N. aim this study was determine whether...
Survival of floret primordia initiated seems critical for the determination grain number and yield in wheat, understanding what determines mortality would help development more robust physiological models determination. The growth juvenile spikes has been frequently considered determinant number, implying that depend on resource availability onset death be related to spike growth. However, this model recently challenged from a study concluding started when most advanced reached particular...

Frost is estimated to cost Australian grain growers <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mi mathvariant="normal">$</mml:mi> </mml:math> 360 million in direct and indirect losses every year. Assessing frost damage manually barley labor intensive involves destructive sampling. To mitigate against significant economic loss, it crucial that assessment decisions on whether cut for hay or continue harvest are made soon after has occurred. In this paper,...
Low temperatures during the flowering period of cereals can lead to floret sterility, yield reduction, and economic losses in Australian crops. In order breed for improved frost susceptibility, selection methods are urgently required identify novel sources tolerant germplasm. However, presence genotype by environment interactions (i.e. variety responses a change environment) is major constraint select most appropriate varieties any given target environment. An advanced method analysis...
