“…Drought is a key factor affecting summer maize growth ( Webber et al., 2018 ; Pokhrel et al., 2021 ). Previous studies had shown that increased drought limited the total biomass of summer maize plants, particularly grain and leaf biomass ( Lesk et al., 2016 ; Shao et al., 2021 ; Wu H, et al., 2021 ). Moreover, drought stress reduced leaf size, stem elongation, and root proliferation, disrupted plant water relationships, and reduced water use efficiency ( Efeoğlu et al., 2009 ; Farooq et al., 2009 ; Zhang et al., 2015 ).…”

“…The level and duration of droughts are closely related to maize growth. At the young ear development of maize, the maize biomass decreased by 54.3% and 61.4% under light (soil moisture at 60 ± 5%) and moderate (soil moisture at 40 ± 5%) drought stress, respectively ( Shao et al., 2021 ). And as the drought increased in severity, the maize biomass and yield decreased ( Zhang et al., 2019 ; Li et al., 2020 ; Liu et al., 2022 ).…”

“…Photosynthesis, the principal source of starch and sucrose, is one of the vital processes affected by water shortage due to decreased CO 2 diffusion into the chloroplast and metabolic constraints (Fan et al 2020;Shao et al 2021). Water de cit stress posed a substantial adverse effect on plant photosynthesis since the contents of vital photosynthetic pigments in most plants decrease signi cantly, thereby reducing the rate of CO 2 assimilation (Moharramnejad et al 2019).…”

“…During the ear development and grain-lling stages, corn plants require considerable water to produce a higher yield. However, the stress sensitivity of the reproductive and grain-lling stages, and overall plant growth and development, determine the success of corn reproduction and the realization of its potential output under low water availability (Seebauer et al 2010;Shao et al 2021). Corn requires 500-800 mm of water during its life cycle.…”

“…Among the environmental factors, ambient temperature and soil water content are two major abiotic factors in the limitation of plant distribution and productivity ( Küsters et al, 2021 ; Yan, Zhong & Shangguan, 2020 ; Kumari et al, 2021 ). Their change will directly and/or indirectly influence plant physiological processes, such as resource allocation ( Farfan-Vignolo & Asard, 2012 ; Forbesa et al, 2020 ), net photosynthetic rate ( Shao et al, 2021 ; Yamori, Hikosaka & Way, 2014 ), carboxylation efficiency ( Liu et al, 2022 ), photochemical efficiency of photosystem II (PSII) ( Aragón-Gastélum et al, 2020 ; Song et al, 2016a ) and water use efficiency ( Liu et al, 2019 ), which then impact the global carbon cycling. Among all the plant physiological processes, photosynthesis plays an important role in substance metabolism ( Ort et al, 2015 ; Zhu et al, 2020 ).…”
