Abstract

Trema is one of tropical forest trees that has many advantages such as wood for building, pulp and charcoal, leaves for medicine and bark for dye material. The constrain of the development of this species is the difficulties of the seeds to germinate and the rapid deterioration of the seeds after being stored. Therefore, there should be a right method to solve the problems. The aim of the study is to determine the proper method of priming to enhance the viability and vigor of trema seeds after storage. Randomized Complete Design was employed in this trial by priming the seeds before and after storage. The treatments werepriming methods including: control (no priming), matriconditioning with ash, osmoconditioning by soaking of 5% H2O2, humidify with water and hydrated-dehydrated process. The observed parameters were thepercentages and speed of germination. The results showed that the treatment method of priming the best for this type of Trema, both before storage and after storage hydration is the treatment of dehydration. Before storage, can increase the value of germination percentage and speed of germination respectively 15% and 0.9% /Etmal. After the storage, treatment hydration dehydration can increase 17% germination and speed of germination of 1.25% / Etmal.

Abstract

Seed deterioration is the process of deteriorated seed in view of viability that has changed its physiological and nutritional content. This paper studies the effect of seed drying and seed storage to the viability and biochemical content of jelutung (Dyera polyphylla (Miq.) Steenis) seeds. Completely Randomized Design was used for different level of seed drying time, i.e. 0, 24, 48, 72, 96 and 120 hours, and Completely Randomized Factorial Design was used for the combination of seed drying treatments of 0, 24, 48, 72, 96 and 120 hours in different rooms for seed storage (ambient room, air conditioned room, refrigerator) with variables of moisture content, germination percentage and nutritional content. Result shows that seed drying and seed storage treatments pursue the change of seed viability and nutritional content of jelutung seed. The period of time in seed drying and seed storage siginificantly influence the moisture content, germination percentage and nutritional composition (lipid, carbohydrate, protein). The longer time of seed drying will effect significantly to the moisture content and germination percentage, increasing the lipid and protein and decreasing carbohydrate. Jelutung seed that was stored in air conditioned room had better viability compared to ambient room and refrigerator.
