Abstract: SURAT NUGLOR, University of the Philippines at Los Banos, February 1986, Effect of Propyl Gallate and Silica Gel on Soybean (Glycine max ( L) Merr Seeds Under Different Storage Conditions. Major Adviser: Dr. Renato C. Mabesa This study was conducted to determine the effect of propyl gallate, a lipid antioxidant, and silica gel, a desiccant, on soybean seeds under different storage conditions. The different -gage conditions employed were open storage. Felled tin can, sealed plastic bag and sealed bag placed in sealed tin can. In a given -forage condition, there were three treatments namely; propyl gallate treatment, addition of silica gel and a control. Seed moisture content, germination percentage and seed vigor were evaluated every month for a period of six months. fatty acid content was also determined at and sixth month of storage. 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 germ inability 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, act and closed containers to prevent the s of seed viability and to ensure high percent-of seed germination in the succeeding growing seasons.

SURAT NUGLOR, University of the Philippines at Los Banos, February 1986, Effect of Propyl Gallate and Silica Gel on Soybean (Glycine max ( L) Merr Seeds Under Different Storage Conditions. Major Adviser: Dr. Renato C. Mabesa
This study was conducted to determine the effect of propyl gallate, a lipid antioxidant, and silica gel, a desiccant, on soybean seeds under different storage conditions. The different -gage conditions employed were open storage. Felled tin can, sealed plastic bag and sealed bag placed in sealed tin can. In a given -forage condition, there were three treatments namely; propyl gallate treatment, addition of silica gel and a control. Seed moisture content, germination percentage and seed vigor were evaluated every month for a period of six months. fatty acid content was also determined at and sixth month of storage.
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 germ inability 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, act and closed containers to prevent the s of seed viability and to ensure high percent-of seed germination in the succeeding growing seasons.
