PENGARUH JENIS KEMASAN DAN LAMA SIMPAN DALAM RUANG BERSUHU KAMAR PADA VIABILITAS BENIH BUNCIS (Phaseolus vulgaris L.)

Abstract

During storage, bean seeds (Phaseolus vulgaris L.) will continue to experience viability decline. One effort to slow down the rate of decline is the use of appropriate packaging materials. This study aims to determine the type of packaging that can maintain high bean seed viability during the storage period of 0-8 months at room temperature of approximately ±28°C. The research was conducted from September 2020 to May 2021, at the Seed and Plant Breeding Laboratory, Faculty of Agriculture, Lampung University. This study used three types of packaging treatments: aluminum foil (AF), black plastic (PH) polyethylene, and transparent plastic (PB) polypropylene, applied in a Complete Randomized Block Design (CrBD) with five replications. Data analysis was conducted using regression analysis with Sigma Plot 12.0 software to express the equation ŷ=f(x) and the Student's t-test to compare the mean viability of bean seeds from 0-8 months. The results of the study indicate that the comparison of linear coefficient (bi) and mean of each viability variable showed no significant difference between packaging types. In fact, there was a higher decline in viability in black plastic packaging between 4-8 months, ranging from 74.24% to 48.48%. Aluminum foil packaging was able to maintain the highest viability of bean seeds in the 8th month (81.5%), transparent plastic packaging in the 6th month (81.2%), and black plastic packaging in the 2nd month (87.12%).
