The flowering stage of rice is particularly sensitive to high temperatures, making it crucial to study their effects on spikelet fertility and cultivation techniques. To mitigate high-temperature damage to rice and enhance food security, this paper reviews the characteristics and mechanisms of rice floret opening, anther dehiscence, pollen scattering, pollen germination, and pollen tube elongation under high-temperature stress. It clarifies the regulatory mechanisms of heat tolerance during rice flowering and proposes cultivation measures to alleviate high-temperature damage. This paper offers new insights into heat resistance mechanisms and cultivation technologies at the rice flowering stage, with promising implications for future research.

The golden apple snail, Pomacea canaliculata, as an invasive species, poses a significant threat to rice production, garnering extensive attention in China. From sowing to field sundrying, rice is susceptible to being bitten by P. canaliculata. During sowing, it bites the embryo of rice seeds, and at the seedling stage, it attacks the entire seedling, leading to a reduction in rice seedlings and effective tillers, significantly impacting rice yield. This paper reviews the species, biological characteristics, damage patterns in paddy fields, field prevention and control technology, and resource utilization of apple snails. The aim is to lay a foundation for further prevention and control measures in paddy fields, ultimately increasing rice yield and quality and minimizing economic losses for farmers.
