Other claims from this paper (13)
- Intervention effect Low R/FR significantly reduced wheat yield.
- Observation Developmental failure of tiller III accounted for over 65% of total yield loss.
- Intervention effect Low R/FR arrested stem elongation and spike differentiation of tiller III.
- Observation Most tiller III aborted during the stamen and pistil primordium stage under low R/FR.
- Intervention effect Low R/FR significantly reduced net photosynthetic rate of fully expanded top leaves.
- Intervention effect Low R/FR inhibited carbohydrate export from leaves to stems.
- Intervention effect Low R/FR significantly increased soluble sugar content in leaves.
- Intervention effect Low R/FR lowered soluble sugar content in stems.
- Mechanism Limited assimilate supply allocated more carbohydrate to low-position tillers.
- Intervention effect Low R/FR significantly reduced cytokinin in young tiller III spikes.
- Mechanism Low R/FR inhibited cytokinin synthesis and promoted degradation.
- Intervention effect Low R/FR induced abscisic acid synthesis in young spikes.
- Mechanism Low R/FR hormonal change inhibited young spike progression.
