“…Physiological traits are commonly examined to assess drought tolerance in many crops (Gesimba et al, 2004;Songsri et al, 2009;Jangpromma et al, 2010bJangpromma et al, , 2012Makbul et al, 2011;Bera et al, 2014). In a previous report, 10 sugarcane cultivars (Uthong 6, Khon Kaen 80, K86-161, Khon Kaen 3, 03-4-425, KU60-1, Phill66-07, B34-164, Uthong 2, and LF82-2122) were selected to evaluate their adaptation ability on the basis of the chlorophyll content, root traits, water use efficiency, and growth characteristics of above-ground parts under drought stress and rehydration conditions (Jangpromma et al, 2010b(Jangpromma et al, , 2012.…”
