Abstract
One effective and efficient selection method to obtain initial information on drought-tolerant genotypes is to observe growth in the germination phase using PEG (Poly Ethylene Glycol). The purpose of this study was to examine the morphological response of Lampung local rice, Lumbung Sewu Cantik variety under PEG-induced drought stress in the germination stage. The concentrations of PEG given were 0%, 10%, and 20%. The research design was a completely randomized design with three replications. Observational data were analyzed for variance at the level a test = 0.05 and further analysis used Duncan's Multiple Range Test (DMRT). Observation of morphological responses showed that PEG induced water stress which affected the growth of Lumbung Sewu Cantik rice varieties during germination. Plumulae growth was inhibited because the concentration of PEG increased. However, the radicle root grew longer at 20% PEG. In addition, Lumbung Sewu Cantik can maintain the dry weight of the radicle and seminal root at increased PEG concentrations.
