Abstract:
Rubber seeds are recalcitrant seed that are susceptible to fungal attack during storage, therefore it will lose strorability in a short time. The purpose of this study was to test the ability of polyethylene glycol 6000 (PEG 6000) to maintain strorability of shelled rubber seeds and the efficacy of fungicide to reduce fungal attack during storage. Completely randomized design was applied with two factors and three replications, i.e., PEG 6000 (%w/v): 0, 15, 30, 45, 60% and fungicide (active ingredients were Pyraclostrobin+Metiram): g/1 kg of seeds): 0, 10, 20, 30 and 40 g. The results showed that 30% PEG maintained strorability of 12 and 16 days where the fungus attacks were 18 and 42%, respectively. Fungicide of 40 g/1 kg was effectively inhibited the growth of fungal during storage, where at 12 and 16 days had fungal attack of 19 and 40%, respectively. The combination of PEG-6000 30% and fungicide of 40 g/1 kg was effective in improving the seed viability, the seeds were able to stand fungal attack during storage of 16 days to 18 with 96% germination. PEG 6000 and fungicide blended with the right combination as a media store, had significant effect in maintaining seed viability.
