Levels of trehalose were enhanced by the reduction of WAS in the two sugarcane cultivars . This was observed after the 60th stressed day and this increase was found to be 12% higher for cultivar IAC91-5155 when compared to IAC91-2195 .evaluated the sugarcane variety IAC91-5155 under water stress and observed a trehalose accumulation of 25.9% (increase of 0.54 μmol g–1 fresh mass weight) at the 60th day under stress, reaching concentrations of trehalose of 2.54 μmol g–1 of the fresh weight. There is a distinction among cultivars regarding the ability of trehalose biosynthesis, regardless of the level of soil moisture and period under stress
