Other claims from this paper (13)
- Association Tongil-type rice showed a larger sink size than japonica under both ambient and high temperature conditions.
- Mechanism The larger sink size of Tongil-type rice is mainly due to its higher number of secondary rachis-branches and spikelets on SRBs per panicle.
- Association Tongil-type rice had a higher number of secondary rachis-branches and spikelets on SRBs per panicle than japonica.
- Association The number of spikelets and rachis-branches per panicle was highly positively correlated with the number of SRBs and spikelets on SRBs per panicle (r above 0.95).
- Association Tongil-type rice had a higher percentage of ripened grains and head rice than japonica under both conditions.
- Intervention effect Under high temperature, Tongil-type rice showed a significant increase in the numbers of spikelets, rachis-branches and SRBs per panicle.
- Intervention effect Under high temperature, japonica rice showed no significant change in sink size.
- Intervention effect High temperature significantly reduced the percentages of ripened grains and head rice in both ecotypes.
- Association The decrease in ripened grain percentage under high temperature was larger in Tongil-type rice than in japonica.
- Association Under high temperature, head rice percentage was reduced more in japonica than in Tongil-type rice.
- Association In both ecotypes, the percentage of ripened grains was higher in primary rachis-branches than in SRBs under ambient and high temperature conditions.
- Association Under temperature rise, the decrease in ripened grain percentage was larger in SRBs than in PRBs.
- Recommendation Breeding rice varieties with an increased number of PRBs rather than SRBs would be desirable to minimize the negative impact of warmer climate on grain ripening.
