Teak planlets (Tectona grandis) of Salomon clones were irradiated by gamma rays to induce genetic variability for growth improvement. The objectives of this research were to analyze the radiosensitivity of T. grandis Salomon clones by gamma ray irradiation and to analyze the genetic variations using Random Amplified Polymorphic Deoxyribonucleic Acid (RAPD). For those purposes, teak planlets were irradiated using gamma rays at 5 different dosages, those were 0 Gy, 10 Gy, 20 Gy, 30 Gy, and 40 Gy. Lethal doses50 (LD50) and reduced doses50 (RD50) were obtained using Curve-fit Analysis. Furthermore, the irradiated planlets were subcultured on medium MS + 0.1 kinetin (M1V0) the surviving M1V0 plantlets were multiplied to MS + 0.1 kinetin, so it is obtained the M1V1 generation. Genetic variation of the mutant was molecularly analyzed using RAPD methods and the variability was calculated using Analysis of Molecular Variance (AMOVA). Results of this research showed that lethal doses50 (LD50) and reduced doses50 (RD50) values were obtained at 24.5 Gy and 7.85 Gy, respectively. It includes genomes of small size and a small number of genomes. The genetic variation of mutant individuals in among and within the treatment of gamma irradiation was 16% and 84% according to AMOVA. It means that the dominant effect of genetic material caused genetic variation in mutant M1V1 generations. This dominance of genetic material could be caused by the response combination of tissue culture treatment and genetic factors that had the potency to be used as materials to select desired clones in the next stage.

Evaluation of land rehabilitation (revegetation) activities is necessary for measuring the extent of success of the ongoing activities in rehabilitating and recovering degraded lands. One way for evaluating the success of land rehabilitation (revegetation) is by determining the changes of micro enviroment. The objective of this research was to study the changes of micro environment in various types of revegetated land cover, including scrub/bush land (SB), agricultural land (TP), monoculture teak (JM) and mixed crops (TC) in Ciliwung upper watershed. Research results showed that the highest air temperature and soil temperature were obtained at SB, respectively at 32.8 °C and 26.5 °C, and the lowest at TC, respectively at 28.1 °C and 20.7 °C. Relative humidity and soil moisture were highest at TC (72.3% and 96%) and lowest at SB (60.8%), and the lowest soil moisture occurred at JM (45%). The highest infiltration rate occurred on TP (475.5 mm h-1, very rapid), followed by JM (117 mm h-1, fast) and TC (80 mm h-1), and the lowest at SB (17.65 mm h-1, medium slow). Erosion reductions occurred after 6 years of the revegetation activities with the following results:TC (96,676.1 ton year-1 ha-1), JM (10,790 ton year-1 ha-1), TP and SB (52,867.9 ton year-1 ha-1 and 24,612.6 ton year-1 ha-1). The micro environments for all land cover types were better after revegetation activities.

Germination of teak is often poor. The study on fruits and seeds germination of Java teak, Muna teak, and Malabar Muna teak was conducted in a series of laboratory and greenhouse experiment. Teak fruits have saveral types of dormancy. So, fruits need pretreatment before they were planted. A recommended pretreatment of teak fruits is to soak the fruits during the night and dry them in the sun during the day.Keyword: teak, Tectoca grandis, fruit germination, seed germination

Mycorrhizal symbiosis is the result of mutualistic interactions between plants and fungi. Melinjo (Gnetum gnemon) naturally associate with ectomycorrhizal Scleroderma sinnamariense and Scleroderma sp. fungi. Artificial inoculation can be applied to young seedlings (1-2 months old), before the roots contain woody material. The purpose of this study was to apply the root pruning techniques to improve gnetum mycorrhizal seedlings production. The study was conducted in a greenhouse using 7 months old seedlings. The treatments consisted of 3 root pruning levels (0, 30, and 50%) and ectomycorrhizal fungi inoculum (control, mycorrhizal seedlings, and soil inoculum). Observations were carried out for 4 months to the seedling growth and root colonization by ectomycorrhizal fungi. Height, diameter, and biomass of melinjo seedlings in all treatments were not significantly different. Thus, root pruning activities do not affect the growth of seedlings. Artificial inoculation produce mycorrhizal seedlings, whereas controls were uninfected. Root pruning increased number of root branching. Root pruning at level 50% increased mycorrhizal seedlings production, but the percentage of root colonization was not significantly difefernt at all pruning levels.

Root pruning technique may improve new lateral growth. The purposes of this research are to analyse the combined effect of root pruning and inoculum ectomycorrizal types on the growth of gnetum seedling (Gnetum gnemon). This research using split plot design. The source of ectomycorrizhal inoculum as main plot consist of 3 types: control, infected seedling of ectomycorrhizal, and soil inoculum. The root pruning level as sub plot also consist of 3 types: 0, 30, and 50%. Observation is conducted on month 5th and 6th after treatment. The result of this research indicates that root pruning technique on 7 month seedling able to enhance melinjo seedling’s growth and increase ectomycorrhizal colonization (Scleroderma spp.) after 6 months observation. The source of inoculum was able to enhance ectomyrorrhizal colonization but had no significant to gnetum seedling’s growth on month 6th after treatment. Interaction between root pruning 30% and fungal inoculation with soil inoculum source can improve gnetum seedling growth.

Morphology and anatomy characteristics often used to identify ectomycorrhizal fungi. We used three Scleroderma spp. (Scleroderma columnare, S. dictyosporum), and S. sinnamariense) and inoculated to Shorea pinanga, Pinus merkusii, and Gnetum gnemon. After 6,8, and 10 months, each root tips were collected to determined hyphae colour, branching pattern, clamp-connection, hartig net and mantle. This result revealed that S. sinnamariense did not form association with S. pinanga and P. merkusii but form association with G. gnemon. On the other hand, S. columnare and S. dictyosporum could form association with all the host plants. S. columnare and S. dictyosporum formed white hyphae while S. sinnamariense formed yellow hyphae with monopodial branching pattern. The depth of hartig net and mantle was increased by timed. Key words: ectomycorrhizal fungi, hartig net, mantle, Scleroderma

Acclimatization is an attempt to conditioning the plantlets or micro shoots propagated by tissue culture to the environment outside the bottle. This study aims to know the effect of rooting and media acclimatization on the growth of tembesu plantlets in vitro cultures. Two experiments were conducted, these were (1) rooting (in vitro and ex vitro), and (2) type of acclimatization media ( 100% sand, cocopeat + rice husk, sand + cocopeat , sand, rice husk, and sand + cocopeat + rice husk). Based on the data analysis rooting significantly affects the variables growth (percentage of survival and the number of roots) at the acclimatization stage of tembesu.The percentage of planlets survival in the acclimatization are 80percent for in vitro rooting and 75percent for ex vitro rooting, while on stage after acclimatization percentage of survival are 75 percent for in vitro rooting and 67 percent for ex vitrorooting. In vitro rooting have a better growth than ex vitro rooting, but the plants grown from ex vitro rooting are more resistant to stress. The best acclimatization media for tembesu is 100 percent of sands.

Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.Keywords: Brachiaria decumbens, Gliricidia sepium, mining reclamation, nursery, Shorea leprosula
