Abstract

The natural regeneration withdraw of  nyatoh (Palaquium sp.) is a regeneration that withdrawn around the mother tree at natural forest and one of the multiple instruments that can be used. Therefore,  the preparation process of natural regeneration that carried from the withdrawal place to the seedling place needs a special treatmentproses persiapan anakan alam yang dibawa dari tempat pencabutan ke persemaian memerlukan adanya perlakuan khusus yaitu pro it is packing by using some kinds of storage places. The objective of the research was to find out the good storage places for the withdraw of natural regeneration of nyatoh (Palaquium sp.)  that used from withdrawal place to seedling place.  The research used Complete Randomized Design that consisted of 5 treatments, they were (P1) Stem of banana bunch, (P2) gunny  sack, (P3) Newspaper, (P4) Carton that layered by transparant plastic, (P5) coconut fiber, with 3 times repititions and each repitition consisted of i natural regeneration. The observed parameter involved height increase, stem diameter increase, and leaf number increase. The five storage places that triedwere good  to be used bacause of their abilities to defend the humidity of withdrawal to be well remain for 24 hours. The result of the research showed that the growth of withdrawal of nyatoh (Palaquium sp.) natural regeneration after storaged on different place had unreal influence to the three observation paranmeters. From the three observation parameters, they were the average of height increase, the average of diameter increase, and the average of leaf number increase, the influence of given treatments stated consistent of each treatment. Which the result of the three parameters in a series were the stem banana bunch (P1) 2.32 cm, 0.47 mm, 2.37 sheets, gunny sack (P2) 2.03 cm, 0.39 mm, 2 sheets, Newspaper (P3) 1.91 cm, 0.34 mm, 1.75 sheets, Carton that layered by transparant plastic (P4) 2.11 cm, 0.43 mm, 2.25 sheets, and Coconut fiber (P5) 2.01 cm, 0.37 mm, and 1.75sheets. Keywords: storage place, natural regeneration withdraw, nyatoh

Abstract

Red Jabon is one tree species with high prospects for forest plantation and reforestation plants in Indonesia and expected to meet the demand for wood in the domestic and international markets. Extraction of seeds is one way to maintain seeds quality red Jabon (Anthocephalus macrophyllus (Roxb.) Havil). The use of calcium oxide (Ca(OH)2) which contains the elements calcium (Ca) is one way of extracting the seeds that need to be applied to the Jabon seeds protected by the flesh. This study aims to determine seeds quality of red Jabon on various methods of extractions of seeds so as to obtain an appropriate extraction method to maintain seeds quality of red Jabon. This study uses a completely randomized design (CRD) consisting of four (4) treatment that E0 (without treatment extraction), E1 (extraction dried by sun-drying for two days), E2 (extraction wet by soaking for 24 hours) and E3 (extraction soaking with lime solution 20 g/l for 25 minutes). Each treatment repeated 4 times, so there are 16 experimental units. The parameters measured were the percentage of pure seed, the percentage of moisture content, weight of 1000 grain seeds, germination, the peak value, the average value of daily germination and the value of germination. The results showed that the extraction treatment E3 able to improve the physical quality of seeds plants red Jabon high of 0,021 grams (weight of 1000 grains), 75.886% (purity), 24.114% (dirt seeds) and 5.117% (moisture). E3 extraction treatment was also able to increase seeds viability red Jabon best is 52.2% (germination), 0.508% /day (peak value of germination), 1.74% /day (daily germination value), and 0.885% /day ( the value of germination).Keywords: Anthocephalus macrophyllus (Roxb.) Havil, calcium oxide, seeds quality
