Abstract

Fungi are one of the main causes of damage to seeds. Fungi can be a pathogen or saprophyte such as Aspergillus sp. and Fusarium sp. The purpose of this study was to determine the effects of filtrate fungus Aspergillus sp and Fusarium sp on seed viability and seedling growth performance of Sengon (Paraserianthes falcataria). The experiment design used was the Completely Randomized Design (CRD), with treatment: control, filtrate of Aspergillus sp and Fusarium sp filtrate. Each treatment was repeated 4 times. Variables measured include germination, percent of live seed, height, diameters, biomass, root shoot ratio, and the index quality seeds. The results showed that the fungus Aspergillus sp filtrate and Fusarium sp significantly affect seed germination, life percent, height, diameter, NPA, IMB, and biomass of seedlings Sengon. The filtrate of fungus Aspergillus sp and Fusarium sp may cause the decrease in seed viability and seedling vigor of Sengon.Keywords : Sengon (Paraserianthes falcataria), seeds, seedlings, fungi, Aspergillus sp, Fusarium sp.

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.

Abstract

Eucalyptus pellita seeds have a very small size, so that it needed techniques of seed sorting using sieves to increase quality of the physical and the physiological. This study aims to determine sieve size for sorting seeds of E. pellita so as to maintain viability.  E. pellita seeds used in this study comes from seedling seed orchard (KBS) in southern Sumatra, South Kalimantan, and Riau. Seed sorting is done with some sieve size namely 200 µm, 400 µm, and 600 µm. Parameters measured were the purity, weight of 1000 grain seeds, and germination.  The results showed that the size of a 600 µm of sieve is appropriate for sorting seeds E.Pellita, because it can result in weight of 1000 grains (0.0362 grams), purity (60.54%) and higher germination percentage (184 sprouts/0.1 grams)  than the others.
