Kemunduran Benih Kedelai Akibat Pengusangan Cepat Menggunakan Alat IPB 77-1 MM dan Penyimpanan Alami

Abstract

Seed deterioration characterized by decrease in viability, vigor and an increase in free fatty. This research was conducted to determine the comformity of the decrease in viability, vigor and an increase in free fatty acids of soybean seed of varieties Anjasmoro and Wilis has aging using accelerated aging machine IPB 77-1 MM compared to natural storage and to determine correlation between viability and vigor compared to free fatty acids. The research consisted of two experiments the natural storage and accelerated aging. Natural storage consists of 5 of storage periods of 0, 2, 4, 6, 8 weeks while accelerated aging consists of 5 of aging periods of 0, 15, 30, 45, 60 minutes. The result showed that the conformity (significant) decrease in viability and vigor between natural storage for 8 weeks compared to accelerated aging for 60 minutes, while in free fatty acids absence of conformity (not significant) between natural storage for 8 weeks (assumed after natural storage for 8 weeks will be increase free fatty acids) compared to accelerated aging for 30 minutes (Anjasmoro) and 15 minutes (Wilis). Viability and vigor compared to free fatty acids had negative correlation, it means increase in free fatty acids effect to decrease in viability and vigor.
