“…However, most of them have focused on early or long-time responses, or in a single variety with or without time series, or between multiple varieties (often without time series), or on media, or non-industrial crops, which limit the application in field improvement in real farming. Different durations of drought treatment were used in existing reports (Kang et al, 2011;Spieß et al, 2012;Yan et al, 2012;Chung et al, 2016;Ogbaga et al, 2016;Shan et al, 2018;Chen et al, 2019;Zenda et al, 2019;Marchin et al, 2020). We propose that long-term drought stress should be relative long time e.g., many weeks, usually spanning one or more developmental stages, which may cause severe damage to growth and yield during farming.…”
