【 摘 要 】

This study was aimed at determining cacao varieties that are tolerant to drought stress and assessing the effectiveness of the use of PEG 6000 as a media simulation to drought stress. Experiment was arranged in a Completely Randomized Design (CRD) non-factorial, replication four times. PEG concentration, consisted of 4 levels, namely control, 15%, 20%, and 25%. PEG concentration on 25% exerted significant effects on viability for twelve days. While PEG concentration on 20% and 15%.
