Abstract: The warming effect resulting from global climate change posed a serious threat to the safe production of rice. Unlike short-term and occasional high-temperature stress, the temperature increase associated with climate warming was relatively small, and its actual impact was closely linked to the baseline environmental temperature, exhibiting a cumulative effect. In the growth cycle of rice, it showed long-term and phased characteristics and should not be simply equated with abiotic stress. To clarify the potential impacts of future climate warming on rice production, numerous studies have begun to focus on the effects of warming on rice growth and development and the underlying causes. This paper reviewed the responses of rice yield formation and nitrogen uptake and utilization processes to the warming effect, along with the associated physiological mechanisms, compared the differential responses of rice growth to daytime versus nighttime warming, and analyzed future research directions and priorities for studying warming effects on rice. The aim was to provide theoretical references for ensuring stable rice yields and improving nitrogen use efficiency.
