Abstract

Three progeny trials of nyawai (Ficus variegata Blume) were established in Mangunan, Bantul, Yogyakarta. The trials were grouped in three sublines based on their original provenances: Lombok, Banyuwangi and Cilacap-Pangandaran. Each subline was laid out in Randomized Completely Block Design (RCBD) comprising 15-19 families.This study was aimed to observe growth variation and genetic parameter of the three sublines progeny trial at six and twelve months after planting. Analysis of variance was made to observe family effect for height and diameter, then the component of variance of each trait was used to estimate the heritability and genetic correlation. The results of study showed that at 12 months of age the survival rate of the trial was more than 90%, indicating high adaptability of the species to the trial site. Family effect on growth traits tended to increase as the trees getting older. Except for diameter in sub-line of Banyuwangi, estimation of individual heritabilities for height and diameter traits ranged from 0.015 to 0.241 and 0.017 to 0.096 respectively, with the corresponding for family heritabilities of height and diameter traits ranged from 0.09 to 0.434 and 0.123 to 0.352 respectively. It suggests that genetic control of the traits at both individual and family level were weak in the early growth. Genetic correlation between the two growth traits were varied among the sub-lines, indicating the character and growth pattern of nyawai seemed to be different among the sub-lines.

Abstract

Suren (Toona sinensis) is a potential multipurpose species that is more cultivated at upland community forests, especially in Java and Sumatra islands. This research was aimed to assess the variation of fruit and seed morpho-physiological characters and to investigate the contribution of geoclimate and genetic factors on the fruit and seed morpho-physiological characters of suren. Seeds were collected from seven populations in West Sumatera, Jambi and West Java on March – May 2015. Morphological parameters measured were size and weight of fruits and seeds, while the physiological parameters measured were seed germination and storability. Analysis of variance revealed significant morpho-physiological differences among populations for all the morpho-physiological parameters studied. Cimalaka population provided the better seed quality compared to seed quality from the other populations, mainly for seed physiological parameters. Most of the parameters was not correlated with geo-climate factors, except for number of empty seed that negatively correlated with mean annual temperature and seed wing width negatively correlated with altitude. Genotypic variance and genotypic coefficient of variance for all fruit and seed parameters were found to be higher than corresponding environment variance and environment coefficient of variance, indicating that the genotype explained most of the variance for these parameters. In particular, high heritability values coupled with high genetic gain were found for germination capacity and germination speed. Principal component analysis of various parameters of fruit and seed revealed that most of the geographically distant populations are genetically close.

Abstract

Swietenia macrophylla King is one of popular tree species for timber product in Java. In order to increase the productivity of planting stock production at nursery, this research was conducted. The objectives of this research was to study the influences of sowing method and NPK fertilizer application on the growth of mahogany seedlings at nursery. The treatments were sowing methods (with and without pricking out), types of NPK fertilizer (grain and solution) and the dosages of NPK fertilizer (0, 0.2, 0.4 and 0.6 gram/seedlings). The result showed that sowing methods and type of NPK fertilizer did not give significant effect on the growth of mahogany seedlings. The dosages of NPK fertilizer caused significant different on the variation of height, diameter, total dry weight and seedling quality index. The application of NPK fertilizer at 0.6 g/seedlings/month showed the best result i.e: the seedling heigth (42 cm), stem diameter (5.15 mm), total dry weight (5.28 g) and seedling quality index (0.38).

Abstract

Acacia mangium has been planted on large scale of industrial forest plantation in Indonesia, especially in Sumatera and Kalimantan islands. It has been reported that large area of mangium plantations have been infected rot root disease caused by Ganoderma sp. To date, there was no information of mangium which resist to Ganoderma sp. The study had by carried out with two aims : (1) isolate a compound with antifungal properties, the antifungal was identified as  p-Methoxybenzylidene p-aminophenol in the category of phenolic compounds. from the roots of healthy mangium, and (2) determine the concentration of antifungal compound from roots of healthy mangium. The roots of healthy mangium from the first generation seedling seed orchard in Wonogiri, Central Java, were used. Mangium roots which had had their external and internal parts separated were  macerated in a solvent of nhexane and methanol. Methods of the isolation of the antifungal compound were thin-layer chromatography (TLC), column chromatography and thin layer preparative chromatography. The antifungal was identified as p-Methoxybenzylidene p-aminophenol in the category of phenolic compounds. Determination of the concentration of the antifungal compound was done by a TLC densitometer on six different families of trees. The results revealed that the antifungal compound was successfully isolated in its from methanol extract from the interior of the root. Results of identification with the TLC densitometer method showed that among the six  families of trees, number 44 had the highest concentration at 40,52% w/w and number 67 showed the lowest concentration at 19,88% w/w.

Abstract

Bakau (Rhizopora apiculata(, one of the species of mangrove, is well known for having true recalcitrat seeds, since they tend to have very short-life cycle. Hence they cannot be stored a long time. Developing improved methods for retarding seedling growth of tropical mangrove is necessary to successfully control growth rates during long-term storage. The aim of the research is to identify the influence of growth inhibitors used were paclobutrazol (250 ppm), NaCl (0,5 %) and aquadest (as a control). The condition for the storage consists of heavy (650 lux), moderate (8935 lux) and light (17593 lux) shadings. The media used including the mixture of sand. A completely randomized design was arranged in a factorial experiment. The results showed that the use of paclobutrazol (250 ppm) was very effective to suppress the growth height of the seedlings. The storage condition of light shading with the intensity of the  day-light and the highest temperatur (L.I= ±17593 lux, T= ±350C) could reduced the speed of seedling growth during storage for 6 months supported by the use of sand as media. Such conditions gave a seedling survival of 98,33%
