e0“maximum grain filling rate, mean grain filling rate, and brown rice weight for superior spikelets showed small difference between the super rice and check rice, but those of inferior spikelets were significantly lower for super rice than for check rice cultivars”

Other claims from this paper (15)
- Observation Superior spikelet grain filling rates and brown rice weight differed little between super and check rice.
- 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.
- Intervention effect MGBG 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.
