e0“Water stress during the late vegetative phase just before spike initiation adversely affected the final number of fertile florets per spike, the reduction in fertile florets being accounted for by fewer spikelet primordia being formed.”

- Intervention effect Water stress at critical times killed florets and sometimes terminal spikelets.
- Intervention effect Late vegetative water stress reduced formation of spikelet primordia.
- Intervention effect Water stress during internode elongation killed terminal and basal florets and spikelets.
- Observation The spike initial had minimum stress sensitivity after terminal spikelet initiation.
- Observation Semidwarf wheat stress effects appeared similar to standard height spring wheats.
- Intervention effect Short days produced more spikelets per spike than long days.
- Mechanism The greater spikelet number in short days was mainly attributed to photoperiod and possibly milder relative water stress.
