“…Kedua perlakuan ini mampu mempertahankan mutu fisiologis benih awal meskipun telah disimpan selama 6 bulan. Sedangkan hasil penelitian dari Hutabarat et al (2018) menunjukkan bahwa perlakuan invigorasi benih kakao (Theobroma Cacao L.) dengan berbagai jenis larutan pada beberapa lama pengeringan nyata meningkatkan laju perkecambahan dan indeks vigor benih. Jenis larutan terbaik terdapat pada perlakuan jenis larutan air kelapa 50 % yang menghasilkan laju perkecambahan 5,51 hari dan index vigor benih sebesar 3,79.…”

Nyamplung (Calophyllum inophyllum L.) is one of forestry plant that has double benefits (economic and ecological). One of the problems faced in the development of nyamplung is its recalcitrant seed, which can not be stored for long periods. To increase the viability of nyamplung seed during storage, seed invigoration techniques are required. Invigoration is the treatment given to seeds before planting with the aim of improving germination and growth of sprouts. The purpose of this research is to know the proper invigoration technique on nyamplung seed during storage. The experimental design of the research was used Completely Randomized Design (CRDL) with factorial. There are 2 factors treatments: the first factor of: Invigoration treatment (control, osmoconditioning with soaking in aquades for 24 hours, osmoconditioning with immersion in PEG-6000 concentration 15 % for 24 hours, matriconditioning with moisture of newspaper (CD) for 2 hours, and matriconditioning with moisture ash scrub for 2 hours) and savings period factor the second factor of period of storage (0, 1, and 2 months). The research was conducted with replication is 4 times, @ each with 50 seeds of seed. The observation of germination is done after normal sprout growth, which it has of a pair of leaves. The parameters observed were germination and germination rate. The results showed that the proper invigoration technique on nyamplung seed during storage was the treatment of matriconditioning with moisture of newspaper (CD) for 2 hours. With this treatment it can increase the viability of seed nyamplung (germination) at 42 % and vigor seed (germination rate) at 0,56 % /etmal. results at the end of the abstract. The longer the storage period will cause the value of germination and the speed of germination to decrease.

“…PEG 6000 at concentrations of 5-20% produces osmotic potentials ranging from -0.3 bar to -6.7 bar (Michel & Kaufman, 1973;Mexal et al, 1975), therefore, they are often used for seed selection (Shao et al, 2015). PEG treatment on cocoa seeds has been carried out by Rahayu et al (2014) and Hutabarat et al (2018) which uses PEG to maintain seed quality. According to Rahardjo (1986), PEG was used to maintain the viability of cocoa seeds during seed storage and delivery.…”

The availability of drought tolerant rootstock becomes one of solution to obtain tolerant cocoa clone at drought condition. The production of rootstock is easier and faster by using prope-legitimate seeds as plant materials. Seed germination selection phase can accelerate the obtainment of tolerant cocoa rootstocks. The tolerance trait of prope-legitimate seeds can be determined by seed germination on media induced by polyethylene glycol (PEG) solution. To determine the tolerant seeds, it is effective by using a specific character as selection criteria. This study aimed to obtain criteria and selection character to determine droughttolerant characteristic of prope-legitimate seed through PEG 6000 induction in the germination phase. The research was conducted at the Agronomy Laboratoryof the Indonesian Coffee and Cocoa Research Institute, Jember, East Java, Indonesia, used split plot design with five replications as experimental design. The main plot was solution of 0% and 6% PEG 6000, while the subplot were prope-legitimate seeds of 13 cocoa clones. The result showed that germination ability and sprout fresh weight were suitable as selection criteria to determine tolerant characteristic of prope-legitimate seeds to drought stress. Based on the value of tress susceptible index and clustering analysis, the tested prope-legitimate seeds were divided into three groups. The group of tolerant genotype consisted of Sca 06, while the group of medium tolerant were ICCRI 03, Sulawesi 02, KW 641, TSH 858, KEE 02, Sulawesi 03, and KW 617. The susceptible group consisted of six genotypes, namely ICS 60, KKM 22, KW 516, Sulawesi 01, and MCC 02.
