Pengusangan Cepat Fisik serta Penyimpanan Benih Koro Pedang (Canavalia ensiformis (L.) DC.) Menggunakan Ruang Simpan dan Kemasan Berbeda

Abstract

Environment of storage conditions (temperature and RH) and type of packaging are important factors affecting seed storability. The aim of this research was to determine physical accelerated aging effect to jack bean seed viability and vigor, get the right storage room and pakaging materials to maintain seed viability and vigor during storage. The research consisted of 2 experiments. Experiment I using Randomize Complete Block Design (RKLT) with physical aging periods as a factor, which consisted of 0, 30, 60, 90, 120, 150, and 180 minutes aging periode. Seed was aged in high temperature (40 ºC) and high RH (>90%) using accelerated aging machine IPB 77-1 MMM type. Experiment II using a nested design with two factors. The first factor was storage room that consist of ambient storage condition and air-conditioned room. The second factor was packaging materials that consists of 3 levels i.e plastic bags, plastic jerrycans, and plastic polypropylene. The results of experiment I showed that phyisical accelerated aging with high temperature and humidity effectively decrease the viability and vigor as well as increase the moisture content of jack bean seed. Experiment 2 showed that the jack been seed storage in ambient storage condition produce higher moisture content, viability, and vigor than storage in air-conditioned room. Jack bean seed storage using plastic bags produce higher moisture content, viability, and vigor than storage using plastic jerrycans, and plastic polypropylene.
