Other claims from this paper (9)
- Intervention effect Heat stress significantly decreased the number of kernels per spike and the grain yield of wheat.
- Intervention effect Heat stress decreased zeatin riboside (ZR) content.
- Intervention effect 6-BA application significantly increased the grain-filling rate and 1,000-grain weight of wheat under heated condition.
- Intervention effect 6-BA application significantly increased the endosperm cell division rate and endosperm cell number of wheat under heated condition.
- Intervention effect 6-BA application increased ZR and IAA contents at 3 to 28 DAA.
- Intervention effect 6-BA application decreased GA3 and ABA contents.
- Association ZR, ABA and IAA contents in kernels were positively and significantly correlated with the grain-filling rate.
- Association GA3 content was counter-productive to the grain-filling rate at 3 to 15 DAA.
- Mechanism The authors suggest the decrease in grain yield under heat stress was due to a lower ZR content and a higher GA3 content during early kernel development, which resulted in fewer kernels and a lower grain-filling rate.
