“…morphological, phenological and physiological modifications (Vadez et al, 2012;Mishra et al, 2014Mishra et al, , 2016. Drought stress is recognized to cause reductions in plant growth, root functioning, leaf area development, cell membrane stability, alterations in biomass and nitrogen allocation in different plant parts, drought tolerance efficiency and geometric mean productivity, similarly, the above parameters and drought indices may gives surety for characterizing drought resistance in many legumes under drought stress (Hamidi and Erskine, 1996;Kurdali et al, 1997;Sio-Se Mardeh et al, 2006;Shrestha et al, 2006a, b;Gunes et al, 2008;Singh et al, 2013;Mishra et al, 2014). Under drought stress the above parameters have been used as source of screening traits in parallel in diverse crop plants, but their relative helpfulness has not been evaluated in lentil groups.…”
