ABSTRACT
This study aims to determine the effect of immersion time on the viability of fruit and seed scarification palm. This research was conducted at the Laboratory of Seed Science and Technology Faculty of Agriculture, Kuala University, Darussalam, Banda Aceh - which lasted from February 20 until May 30 2013. Materials used in this study is the fruit of palm, palm seed as much as 1080, sulfuric acid ( H2S04 ) with a concentration of 10%, hot water with a temperature of 50 ºC, the planting medium is soil, sand, manure, and sawdust at a ratio of 1:1:1:1 (v/v). This study used a completely randomized design (CRD) 3x3 factorial with 3 replications so that there are 27 combinations of treatments. There are two factors studied were long soaking fruit and scarification. Fruit soaking time factor consists of 3 levels ie 3x24 hours, 5x24 and 7x24 hour clock. Factors scarification consists of 3 levels ie skin scratching the back of seed, soak the hot water with a temperature of 50 ºC, H2S04 soak for 3 hours. Variables measured were potential growth, germination, germination delay value, speed of growth, and the time required to reach 50% germination appearance. Results showed that the palm fruit soaking time significantly affect seed vigor shown by the time required to reach 50% of total germination (T50%), and there is no real effect on potential growth parameters (PT), germination (DB), value of delay germination and growth velocity (Kct) are abbreviated long soaking fruit in treatment 3x24 hours (P1) where the value of the time required to reach 50% of total germination peak at 87.33%. Scarification significantly affect seed viability shown by the growth potential (PT) and the effect was not significant on germination observations (DB), the value of the delay germination (NPP), growth velocity (Kct) and the time required to reach 50% of total germination (T50%) were the highest observed in 10 % H2SO4 soak for 3 hours (S2) where the growth potential reach, 58.33%. There was no significant interaction between the long soaking and scarification pieces on all variables palm seed viability and vigor were observed .
