Abstract

Using Organic Priming and Incubation Period for Invigoration of Chilli Seed Expired at Germination Stage ABSTRACT. The purpose of this study was to determine the effect of organic priming and incubation period to increase viability and vigor of expired chilli seeds and interaction between of two factors. This research was conducted in the Laboratory of Seed Science and Technology Faculty of Agriculture, Syiah Kuala University in Banda Aceh, from March until November 2012. Using completely randomized design (CRD) factorial, the first factor is organic priming (banana extract and coconut water) and the second factor is incubation period (24, 48, 72 hours). The results showed that interaction between types of organic priming and incubation period significan affect to increase viability and vigor of expired chilli seeds, especially on potential growth, germination, speed of germination, first count germination and T50. The best treatment showed by using coconut water and 48 hours incubation periods.

Abstract

The objectives of this research were to study physiological and chlorophyll changes during seed ripening and find quick parameters as indicators to determine seed physiological maturity level. A randomized completely block design with 5 treatments and 3 replications was used in this research. The treatments were (1) dark green fruit, 42 days after anthesis (DAA), (2) yellowish green fruit, 47 DAA, (3) fully green fruit, 52 DAA, (4) brownish yellow fruit, 57 DAA, and (5) dark brown fruit, 62 DAA. The results showed that jathropa seed was physiologically mature at 57 DAA with criteria: fruit color was brownish yellow, fruit skin was soft and easily hand-opened, and seed was black. These were also supported by seed dry weight, germination percentage, germination rate and first count germination. There were negative relationships between seed chlorophyll content and germination percentage, germination rate and first count germination.
