【 摘 要 】

To guarantee the continuous supply of seed for supporting plantation programs in city forests, techniques to store the seeds that can prolong their life are required. The objective of the paper was to review the seed storage techniques of 20 (twenty) species of city forest trees, with locally named as: asam jawa, ampupu, bungur, cempaka kuning, cemara laut, damar, gmelina, jati, johar, kenari, kayu afrika, kecapi, mangium, mindi, pulai, rasamala, sawokecik, suren, tusam, and tanjung. The storage techniques of those twenty seed species are classified based on their physiological characteristics, i.e: orthodox (asam jawa, ampupu, bungur, cemara laut, gmelina, jati, johar, kenari, mangium, mindi, sawokecik, tusam, and tanjung), recalcitrant (damar and kecapi), and intermediate (cempaka kuning, kayu afrika, rasamala and suren). The review results indicates that (1) The techniques to store orthodox seeds are to put the seeds in a room with a temperature of 0 C-20 C with a relative humidity of 40%-50% and a seed moisture content of 5% - 7%, (2) recalcitrant seeds are stored at a temperature of 12 C-15 C with a relative humidity of 60% - 70%, and a seed moisture content of 20%-35%, and (3) intermediate seeds storage applies the temperature of 20 C and seed moisture content of 12% - 17%.
