Other claims from this paper (7)
- 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 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.
