Claim · model-written summary

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.

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 Heat stress increased gibberellin (GA3), indole-3-acetic acid (IAA) and abscisic acid (ABA) contents at 3 to 15 DAA.
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.
