Abstract：In the context of global warming， extreme weather disasters combined with high temperature anddroughtoccur frequently，which graduallybecome the mainabiotic stress factorsin corn production，and have seriouslyaffectedthegrowth，developmentandyieldofcorn. Themorphological，structural and developmental characteristics ofmaizevegetative organs（root，stem，leaf）and reproductive organs（female spikes and male spikes）and thechanges ofmaize yield under the combined stressof

high temperatureand drought were reviewed.Theresearch progressonmaize responses to combined heat and drought stress hadbeensystematicallelucidatedfromtheaspectofphysiological functions includingphotosyntheticfluorescence，antioxidantsystems，andendogenous hormones，aswellasfromthe perspectiveof molecularregulation.It is proposedthat future research should integrate multiple omics technologies to systematicallyreveal the mechanism of maize response to combined stressof high temperatureanddroughtfromtheaspects of genes，functional proteins，metabolites totraits，soastomprove the toleranceofmaizetocombinedstress of high temperatureanddrought，ndachieveagricultural disasterreductionandefficiencyenhancement.

近年來，隨著全球氣候持續(xù)變暖，極端干熱天氣的發(fā)生頻率、強(qiáng)度和持續(xù)時間在不斷增加[1-3]，高溫干旱復(fù)合脅迫將成為農(nóng)業(yè)生態(tài)系統(tǒng)普遍發(fā)生的非生物脅迫因素[4-5]。（剩余21178字）
