Rice (Oryza sativa) is one of the most important crops and a food source for billions of people. Anthropogenic global warming, soil erosion, and unstable environmental conditions affect both rice vegetative and reproductive growth, and consequently its final yield. The reproductive phase starts with the transition of the apical meristem from the vegetative to the reproductive phase in which it develops into a panicle and proceeds through the differentiation of the floret and, after fertilization, to the filling of the grain. The physiological events that occur during these stages influence the ability of new seeds to respond to stresses during the future germination phase, a key step for successful seedling growth and future plant establishment. This review explores the impacts of different abiotic stresses on the physiological and molecular pathways of reproductive growth.
水稻（Oryza sativa）是最重要的作物之一，也是数十亿人的食物来源。人为造成的全球变暖、土壤侵蚀和不稳定的环境条件会影响水稻的营养生长和生殖生长，进而影响其最终产量。生殖阶段始于顶端分生组织从营养生长阶段向生殖生长阶段的转变，在此过程中它发育成一个稻穗，并经历小花分化，受精后进入籽粒灌浆阶段。这些阶段发生的生理事件会影响新种子在未来萌发阶段应对胁迫的能力，而这是成功培育幼苗和未来植株生长的关键步骤。本综述探讨了不同非生物胁迫对生殖生长的生理和分子途径的影响。
