This study was undertaken to determine the time-course of floret primordium initiation and
degeneration in relation to thermal time after sowing in various cultivars and tiller positions …

The results showed that the initiation of leaf and bracteal primordia took the S shape, and
that of spikelet and floret took the rise stage of parabolic shape in relation to GDD (growing …

Leaf emergence and primordium initiation were measured in experiments done with
different varieties in a wide range of environments. Leaf initiation, relative to leaf emergence …

A longer duration of stem elongation (from terminal spikelet initiation to anthesis) would
result in a higher wheat yield potential as a consequence of the increase in both spike dry …

Photoperiod and vernalisation both affect the number of leaf and spikelet primordia and,
hence, the duration of the early phases of development in wheat. Temperature also affects …

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 …

Spike grain number, a major component in the yield of wheat, is suspected of being
determined by the sudden death of most of the initiated floret primordia, which occurs at …

Spikelet and floret initiation on main shoots and the two most developed tillers was studied
quantitatively in winter triticale (cv. Grado) and winter wheat (cv. Taras) grown at Rostock …

Survival of floret primordia initiated seems critical for the determination of grain number and
yield in wheat, and understanding what determines floret mortality would help in the …

Floret development is critical for grain setting in wheat (Triticum aestivum), but more than
50% of grain yield potential (based on the maximum number of floret primordia) is lost …
