A study was conducted to evaluate morphological characters that were able to be used as indicators click here of water-deficit tolerance in rice at the germination phase in the Laboratory of Conservation Biology and Biodiversity, Department of Biology, FMIPA, Sam Ratulangi University.The method that was used in this study was germination in the osmoticum solution.Rice cultivars Mira 1 and IR 64 were used and the osmoticum solution was polyethylene glycol (PEG) 8000.Among the morphological characters (i.

e.length acupatch of seminal root, shoot length, root-to-shoot length ratio, coleoptile length, germination percentage and seed vigour index) that were evaluated, root-to-shoot length ratio was able to be used as the indicator of water-deficit tolerance in rice at the germination phase.
