Effect of propyl gallate and silica gel on soybean (Glycine max (L.) Merr.) seeds under different storage conditions [Philippines]
1986
Nuglor, S.
Soybean seeds stored in tin cans, plastic bags placed in tin cans with silica gel and the control in sealed tin cans showed lower seed moisture content, higher seed vigor and germinability compared to the other storage treatments. On the other hand, soybean seeds treated with propyl gallate did not have any protective effect on seed deterioration. This may be due to the toxicity of propyl gallate. The concentration used (40 mM=0.08%) is beyond the optimum level for maintaining soybean seed quality. Total free fatty acid declined in almost all treatments except in the open storage system with propyl gallate after six months of storage. It is advisable to reduce seed moisture content as low as possible prior to the storage of soybean seeds with silica gel in impermeable, compact and closed containers to prevent the loss of seed viability and to ensure high percentage of seed germination in the succeeding growing seasons
