Effective Concentration of Poly Ethylene Glycol on the Growth of Soybean Varieties

Hidayati , Mahfudz , Fathurahman and Sakka Samuddin

Background and Objectives: Priming or pretreatment on seeds using osmotic solution with PEG (Poly Ethylene Glycol) can improve physical, physiological and biochemical characteristics of seeds. The aim of this research is to examine the effect of PEG-4000 concentration on the growth of varieties of soybean. Material and Method: The experiment used Completely Randomized Design (RAL) factorial pattern with two factors. The first factor is pretreatment by soaking the seeds (w/v) into various concentrations of osmotic solution (PEG-4000) for 3 h, consisting of six levels: (1) Soaking the seeds in destilat (R0 = 0 Mpa), (2) 20% PEG (R1), (3) 25% PEG (R2), (4) 30% PEG (R3), (5) 35% PEG (R4) and (6) 40% PEG (R5). The second factor is Soybean Seed varieties with medium seed (10-14 g/100 seeds), which consist of three levels, namely: (1) Mitani varieties, (2) Dering varieties and (3) Wilis varieties (local). The observed variables were germination, germination rate, crown length, root length, canopy and root length ratio and dry weight of plants. The data analysis included regression. Results: Seeds pretreated in osmotic solution (PEG-4000) tend to have a good effect on the growth of each soybean varieties than without PEG. Interaction with 40% PEG treatment yields the highest value for all indicators compared to other concentrations. Conclusion: Interaction of 40% PEG treatment is an effective concentration on the growth of soybean varieties. Dering varieties showed the best growth compared to the varieties of Wilis and Mitani varieties.
