Other claims from this paper (15)
- Observation Superior spikelet grain filling rates and brown rice weight differed little between super and check rice.
- Observation Inferior spikelet grain filling rates and brown rice weight were significantly lower in super rice than check cultivars.
- Observation Grain polyamine concentrations showed a single peak during filling.
- Observation Put peak and mean concentrations were greater in inferior than superior spikelets.
- Observation Spd and Spm peak and mean concentrations were greater in superior than inferior spikelets.
- Observation Spd and Spm peak and mean concentrations were greater in check than super rice.
- Association Grain filling rate and brown rice weight were negatively correlated with Put concentration.
- Association Grain filling rate and brown rice weight were positively correlated with Spd, Spm and their ratios to Put.
- Intervention effect Spd application enhanced three starch synthesis enzyme activities in inferior spikelets.
- Intervention effect Spm application enhanced three starch synthesis enzyme activities in inferior spikelets.
- Intervention effect Spd application increased grain filling rate, seed setting rate and grain weight of inferior spikelets.
- Intervention effect Spm application increased grain filling rate, seed setting rate and grain weight of inferior spikelets.
- Intervention effect Put application produced the opposite effects to Spd and Spm application.
- Mechanism The authors suggest polyamines regulate grain filling.
- Mechanism The authors suggest low Spd and Spm concentrations and ratios may explain poor inferior spikelet filling in super rice.
