Other claims from this paper (8)
- Intervention effect High temperature reduced pollen germination and metabolite synthesis in both rice cultivars.
- Intervention effect High night temperature had more negative effects on rice pollen than high day temperature.
- Intervention effect Exogenous plant growth regulators assuaged the adverse effects of high temperature on rice pollen.
- Intervention effect The combination Vc + Ve + MeJA + Br was the best treatment for every studied characteristic.
- Association Huanghuazhan (HHZ) had higher pollen fertility than IR-64 under high-temperature stress.
- Association Huanghuazhan (HHZ) had better anther dehiscence than IR-64 under high-temperature stress.
- Association Huanghuazhan (HHZ) had greater pollen retention and germination rates than IR-64 under high-temperature stress.
- Association Higher metabolite synthesis in HHZ is associated with its greater tolerance to high temperature.
