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

Lonkida (Nauclea orientalis L.) is a native multipurpose tropical tree species in Indonesia, which a few information regarding its biology and ecology. An experimental research was carried out to examine characters of fruit, seed and seed quality of lonkida growing at different habitat in South East Sulawesi. Fruit and seed was collected from four habitat types, such as dry land, permanent swamp, temporary swamp and temporary swamp savanna. The parameters to be observed were fruit size, seed size and morpho-physiology seed quality. The results showed that fruit size and number of seed per fruit are significantly different among habitats. The mean of fruit’s length and width and number of seed per fruit originated from permanent swamp and temporary swamp is greater than that of fruit’s from lonkida stand growing in the remain habitat’s. Those parameters ranging from 4.99±0.17 to 6.66±0.19 cm for fruit length and 3812±519 to 13.984±1912 seed for number of seed per fruit. Beside, the habitat condition also significantly affected to the characters of seed dimension and seed quality. Permanent swamp was a habitat with seed size and seed weight lower compare to another habitats. However, seeds produced by the lonkida stand growing on permanent swamp habitat and temporary swamp savanna has the higher percent of germination, germination capacity and mean day germination (MDG) than that of the seeds from lonkida stand growing on other habitats. Seed length is positively correlated with seed width and negative correlation with means germination time.

Abstract

Genetic diversity value of offspring might indicate a reproductive success in a forest. Aim in this study was to access genetic diversity values of offspring of Shorea leprosula from different forest types. Leaf samples were collected from six population i.e. a plantation from Carita, and five natural forests from Gunung Bunga A and B, SBK, ITCI and Gunung Lumut. Using four microsatellite markers, the results showed that SBK population maintained high value of genetic diversity. Values of expected heterozygosity (HE) ranged between 0.717 (Carita) and 0.836 (SBK). Values of coefficient inbreeding (F) were insignificant deviated from Hardy-Weinberg Equilibrium, but the value was significant in SBK population. PCA analysis demonstrated a cluster among Gunung Bunga A, SBK, ITCI, and Gunung Lumut. Amova showed that different province significantly contributed 1% to the value of genetic diversity of S. leprosula.

Abstract

Along with the increase of forest plantation development to supply raw material for industry, the utilization of marginal land with high salinity is likely to be an alternative for the plantation of A. mangium. In an effort to increase the improvement of A. mangium to be extensively planted on the widely alternative land, breeding programs were conducted to get trees of A. mangium which are tolerant to environmental stress, such as salt stress. The purpose of this study was to observe the anatomical response of A. mangium collected from several seed sources to salinity stress as a basis for salt tolerance breeding program. The trial consisted of four seed sources arranged in Completely Randomized Design with four level salt stresses(0; 22; 26 and 30 g/l) and 3 replications. The four tested seed sources are two seedling seed orchard (SSO) originated from Papua New Guinea provenance (namely group A and B), one SSO originated from Far North Queensland provenance (group C) and one SSO originated from a combining both provenances (group E). The treatment is given by  watering the seedlings from each provenance with saline solution in accordance with a predetermined concentration of 200 ml per day for 4 months. The observed parameters were stomatal index, length dan width of stomata, number and diameter of trachea, and chlorophyll content. The results showed that in general the differences in salt co ncentration provided a significant effect on anatomical response of A. mangium. Except for the length of stomata, seed source variations were significantly different for all parameters. Meanwhile, seed sources x salt level  interaction did not significantly affect the length and width of stomata. The higher the salt concentration, the lower the stomatal index and chlorophyll content. Conversely, the higher the salt concentration, the higher the amount of the tracheid. However the differences in salt concentration did not give a significant effect on diameter of tracheid. Overall, among the four tested seed sources, group B which is originated from Papua New Guinea provenancewas found to be the most tolerant seed sources to salt stress.

Abstract

The genus of Phytophthora is a destructive plants pathogen. However the existence of these species in plant tissue was hardly to detect because the fungus may also be present as resistant propagules in soil or spread through waterways. This study aimed to test the FTA card as a direct bait to obtain the DNA of  Phytophthora spp and also to investigate the suitability of FTA card as a sampling method. This research used several Phytophthora baits including FTA card followed by DNA extraction and PCR used ITS primers and genus/species specific primers. The result of the study showed that FTA card can be used as a direct bait for Phytophthora spp. and to sample fungal DNA from other Phytophthora baits. However, further optimisation and validation are still required.
