Abstract

ABSTRACTThe research was objected to determine the impact on biochemical and physiological changes of eboni (Diospyros celebica Bakh.) seeds during storage. Completely randomized design was used in this trial with two treatments, i.e storage room condition and storage periods. The results showed that physiological changes of the seeds during storage decreased their germination percentage and seed moisture content. Biochemical changes as indicated by the increase of fat and protein contents, as well as reduction of carbohydrat content following the period of drying and storage were observed. Storing the seeds in an Air-Conditioned room could keep germination percentages at 61,94% with the moisture content at 46,69% for as long as 8 weeks. Based on physiological and biochemical responses, eboni seeds could be classified as recalcitrant type.ABSTRAKEboni  (Diospyros  celebica Bakh.)  merupakan  jenis  tanaman  yang potensial  untuk dikembangkan  padapembangunan hutan tanaman. Benih bermutu tinggi diperlukan dalam program pengembangan jenis ini dan penyimpanan benih tidak dapat dihindari berkaitan dengan penyediaan benih. Penyimpanan benih eboni ditujukan untuk mempertahankan viabilitas benih agar tetap tinggi. Tujuan penelitian adalah untuk mengetahui dampak perubahan kandungan biokimia dan fisiologis benih eboni selama penyimpanan. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap pola Faktorial dengan perlakuan faktor ruang simpan  dan  periode penyimpanan.  Hasil  penelitian  menunjukkan perubahan  fisiologis benih eboni  selama penyimpanan mengakibatkan adanya penurunan nilai daya berkecambah dan kadar air benih ; perubahan biokimia benih eboni selama penyimpanan menunjukkan adanya peningkatan kandungan lemak dan protein serta penurunan kandungan karbohidrat seiring dengan lamanya pengeringan dan penyimpanan ; penyimpanan benih eboni di ruang simpan AC dapat mempertahankan viabilitas benih selama 8 minggu, dengan daya berkecambahnya hingga 61,94% dengan kadar air 46,69 %. Berdasarkan reaksi fisiologis dan biokimia yang terjadi, maka benih eboni dapat dikatagorikan sebagai benih rekalsitran.

Abstract

This study describes a proper methode of seed storage to ensure merbau seeds remain viable after being separated from their host plant, and enable to germinate satisfactory by after planting. The aim of this research is to find out a proper methode of seed storage of merbau seeds. In implementing proper storage methode, three types of factors were tested, i.e : storage container (plastic, can, cloth bags, sack bags and bamboo box), storage room (air conditioned and room/ambient temperature); and storage durations (0, 2,4 and 6 months). The results showed that the most proper seed storage of merbau seeds was by using plastic bag container in an air conditioned room.

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.
