Abstract: | The objectives of this experiment were to evaluate responses of soybean genotype to drought stress generated by polyethylene glycol (PEG) supplementation at germination stage. Evaluations were conducted using four soybean genotypes (MLG2999, MLG2805, B3731, and MSC8606) and two soybean varieties (Dieng and Kerinci). The results indicated that supplementation of PEG in the germination medium reduced germination responses of the soybean seeds. Drought tolerance soybean exhibited different germination responses than that of drought sensitive one. Soybean genotypes that were drought tolerance showed higher index of seed emmergence at 20% PEG, root length at 10% PEG, seedling dry weight and hypocotyl length at 5% PEG, respectively, than the sensitive one. This result confirmed MLG2805 as drought tolerance, and MSC8606 as drought sensitive representatives soybean genotypes. Index of seed emmergence at 20% PEG and index of hypocotyls length at 5% PEG can be used to select drought resistance soybean at germination stage. |
