Abstract

The physical and physiological quality of seeds is a benchmark for determining the quality of a seed in the competitive arena of seed producers because each seed company has its own standards to determine whether the seed is suitable or not. Efforts to overcome the problem of the physical appearance of cucumber seeds use citric acid to improve the physical appearance of the seeds without damaging their physiological quality. The research was carried out from August to November 2023 at PT. East West Seed Indonesia address is Jalan Basuki Rachmad No. 019, Muktisari Village, Tegal Besar, Jember. The research was carried out using a factorial completely randomized design (CRD) consisting of two factors. The first factor is the soaking time (L), which consists of 5 minutes (L1), 10 minutes (L2) and 15 minutes (L3). The second factor is the concentration of citric acid (K), which consists of 1.5% (K1), 2% (K2) and 2.5% (K3). The results showed that the interaction between soaking time and citric acid concentration showed a very significantly different effect on the color brightness level parameters, the best treatment was the notation lightness L1K1 (76.58%), redness L1K1 (4.07%), yellowness L1K2 (23, 33%), color difference (1%). The parameters of growth speed and vigor index showed very significant different effects, the best treatment L2K1 growth speed was 24.73% and the vigor index of the best treatment L2K1 was 98.67%. The germination parameter showed a significantly different effect on the L2K1 treatment of 100%.
