Increasing temperature due to global warming has emerged one of the gravest threats to rice production.The present study examined the influence of high temperature and exogenously applied plant growth regulators on pollen fertility,anther dehiscence,pollen germination,antioxidant activities and metabolites synthesis in pollens of two rice cultivars (IR-64 and Huanghuazhan).Plants were subjected to high day temperature (HDT),high night temperature (HNT).
