The periods of conservation is aimingat takingan optimum potency before they go through another proces, for example giving the priming treatment. The principle of priming is to activate the internal and external resources for maximizing seedling growth by regulating water absortion of embryo. The objective of this research was to measure the effect of conservation periods and priming on the germination capacity of kesambi seed. The experimental design this research is randomly comppetely factorial design, with the main factors are conservation periods (A) and priming technique (B). There are four stages of the conservation periods, such as 0, 4, 8 and 12 weeks at ambient room (t = 25º -27ºC; RH = 80 -90%) and the priming techniques were : control (without priming), hydration-dehydration by H O, PEG 600 (at -5 and -10 bars), 2
