The greater spikelet number in short days was mainly attributed to photoperiod and possibly milder relative water stress.

Verbatim
e0“This was mainly due to photoperiod and possibly also because water stress of the same duration and similar intensity may have been relatively less severe in the prolonged development phases in the short days.”
t0“Wheat”
e1“Greater spikelet number per spike was obtained in the short days (8 h) than in the long days (16 h).”

- Intervention effect Water stress at critical times killed florets and sometimes terminal spikelets.
- Intervention effect Late vegetative water stress reduced fertile florets per spike.
- 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.
