=== Cold tolerance ===

Rice is sensitive to temperatures below 12C. Sowing takes place once the daily average temperature is reliably above this limit. Average temperatures below that reduce growth; if sustained for over four days, germination and seedling growth are harmed and seedlings may die. In larger plants subjected to cold, rice blast is encouraged, seriously reducing yield. As of 2022, researchers continue to study the mechanisms of chilling tolerance in rice and its genetic basis.<ref name="Li Zhang Chong 2022">{{cite journal | last1=Li | first1=Junhua | last2=Zhang | first2=Zeyong | last3=Chong | first3=Kang | last4=Xu | first4=Yunyuan | title=Chilling tolerance in rice: Past and present | journal=[[Journal of Plant Physiology]] | volume=268 | date=2022 | doi=10.1016/j.jplph.2021.153576 | page=153576| pmid=34875419 | bibcode=2022JPPhy.26853576L }}</ref>
