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

Nyawai (Ficus variegata  Blume) is a priority alternative tree species in the establishment of timber plantations. One of the factors determining the success of the development of nyawai forest plantations is the use of high quality seedlings because high quality seedlings would result high productivity stands. Application of fertilizer and mycorrhizal fungi can improve seedling quality. The purpose of this study is to get an optimum combination of fertilizer and mycorrhizal to produce high quality nyawai seedlings. Nyawai fruits were collected from Cibodas Botanical Garden  Cianjur, Ir. H. Djuanda Grand Forest Park (Bandung), and Cikampek Forest Research. The experimental design used was randomized block design (RBD) with factorial pattern. Each replication consisted consisted of 30 seedlings Germination was done by sowing seed on the sprouting tubs contained by sterilized media. Transplanting media used sub soil plus mycorrhizal soil: without mycorrhizal (C0 ), Glomus sp.  (C1 ), Acaulospora sp.  (C2 ) and NPK : 0.0 g  (P0 ), 0.5 g / polybag  (P1 ), 1.0 g / poybag  (P2 ). To produce  nyawai seedling can use a mix media of subsoil + 30% coconut coir dust (coco peat) +10% rice husk (v / v), CMA Glomus  sp and Acaulospora  sp  able to colonize with the roots of nyawai seedlings.

Abstract

Pertumbuhan setek dipengaruhi oleh faktor bahan tanaman (genetik) dan faktor lingkungan. Faktor bahan tanaman meliputi kandungan cadangan makanan, hormon endogen dalam jaringan setek, umur pohon induk, dan tingkat juvenilitas. Tujuan penelitian untuk mengetahui pengaruh asal bahan setek dan zat pengatur tumbuh terhadap keberhasilan perbanyakan vegetatif setek malapari. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) pola faktorial dengan dua faktor yaitu asal bahan setek (anakan dan tunas pangkasan) dan konsentrasi zat pengatur tumbuh IBA (0 ppm; 250 ppm; 500 ppm) dengan 4 kali ulangan. Setiap ulangan terdiri dari 45 setek. Hasil penelitian menunjukkan bahwa materi setek pucuk terbaik adalah tunas dari bibit umur 5 bulan dengan persen setek berakar, jumlah akar panjang akar dan berat kering akar masing-masing adalah 96,05 %; 4,26 helai; 9,5cm dan 0,07 g. Zat pengatur tumbuh IBA hingga 500 ppm belum berpengaruh terhadap keberhasilan perakaran setek. Interaksi antara materi tunas dari tunas bibt dengan penambahan IBA 500 ppm menghasilkan berat kering akar setek tertinggi (0,088 g).
