Abstract

Cendana (Santalum album L.) sebagai tanaman asli Nusa Tenggara Timur  merupakan salah satu tanaman yang memiliki nilai ekonomi sangat tinggi karena adanya kandungan santalol  pada kayu terasnya. Saat ini kesenjangan antara produksi dan permintaan minyak cendana  dunia sangat tinggi. Peningkatan produksi dan kualitas cendana dapat dilakukan dengan serangkaian kegiatan pemuliaan untuk menghasilkan benih unggul secara genetik. Balai Penelitian Kehutanan Kupang telah membangun uji keturunan  generasi pertama cendana di Kabupaten Timor Tengah Utara Provinsi Nusa Tenggara Timur untuk meningkatkan produksi kayu teras, rendemen dan kadar santalol. Rancangan penelitian disusun dengan rancangan IncompleteBlock Design (IBD) yang terdiri …..

Abstract

As a part of tree improvement project of sengon (Falcataria moluccana L. Nielsen) several progeny test  were established in December 2011. One of those progeny test  was established in Bondowoso, East Java.  Row Column Desgin (Incomplete Block Design) was used as experimental design involving 70 families (9 Papua provenance and 1 provenance Solomon), 4 replications (blocks), 4 trees per plot and a spacing of 3 x 2 m. Observations were made at the age of 6 and 12 months, including recorded the percent of survival plants, height, diameter and the gall rust incidence. Results showed that in general, the early growth of individual plant in this plot demonstrated a fairly good performance with the survival rate of 98.5% (6 months old), and 96.9% (1 year old). The early growth of sengon varied significantly between provenances. The best growth demonstrated by provenances from Meagama, Holima and Hobikosi. Early estimation of individual heritability of plant height categorised in low (h2i= 0.07 to 0.11, h2f= 0.16 to 0.21), whereas individual heritability of diameter were catagorised in medium (h2i= 0, 08 to 0.27, h2f= 0.15 to 0.43). Moreover, the positive value of the genetic correlation revealed between height and diameter (0.88 and 0.85). Several individual trees originated from Holima, Meagama and Elagaima exhibited 0% of gall rust disease incidence.

Abstract

Seed orchard A. auriculiformis F1 at Wonogiri, Central Java has attacked by ganoderma caused root rot. To determine the genetic variation, the pattern of spread of ganoderma necessary to somatic incompatibility test and measure the growth. This study used 8 isolates of the fungus ganoderma. Fungi were grown on PDA (Potato dextrose agar), made  parental isolates and paired with each other. The results showed that all pairings  indicated incompatible reactions except self pairings. All self-pairings showed compatible reactions that indicated by miycelia merged on PDA forming a single colony. Incompatible reaction zone is characterized by  sparse zone, demarcation line and pigmentation. The results of somatic incompatibility test,  ganoderma have different genotypes or  it is not a single colony. The result indicates that the distribution of root rot  in Seed orchard A. auriculiformis F1 at Wonogiri, Central Java not only occured by root to root contact.

Abstract

Sandalwood (Santalum album L.), a native plant of Nusa Tenggara Timur, has a very high economic value due to santalol content in the heartwood. Currently the gap between demand and production capability of sandalwood oil is high. Productivity and quality of sandalwood can be increased through a series of tree improvement activities, such as establishing a progeny test to produce genetically improved seed. Balai Penelitian Kehutanan Kupang has established a first generation progeny test of sandalwood at Timor Tengah Utara regency, Nusa Tenggara Timur province to improve the productivity of heartwood, rendemen and santalol contents. The trial was laid out in Incomplete Block Design (IBD) consisting of 65 families, 3 tree-plots, 5 replications with a spacing of 4 x 4 m. This study was aimed to evaluate the growth of sandalwood progeny test at eight months after planting. The result of study showed that average growth of height and diameter are 48.60 cm and 4.55 mm, respectively. The estimates of family and individual heritability for height are 0.06 and 0.03,respectively, while for diameter are 0,16 and 0,10. Genetic correlation between the heightand diameter is 0.87.

Abstract

The mortality of pine seedling in nursery was caused by damping off. Damping off disease is caused by soil borne pathogenic fungus Fusarium subglutinans. To get an effective method in controlling the diseases, is important to understand the effectiveness of biocontrol agent Trichoderma harzianum. The purpose of this research was to comprehend the inhibition mechanism of T. harzianum against F. subglutinans and its effectiveness. The research methods include (1) in vitro application of T. harzianum with Green Fluorescent Protein [GFP] using dual culture method, and (2) in planta application by inoculating T. harzianum with GFP four days before F. subglutinans inoculation, inoculating T. harzianum and F. subglutinans at the same time, and inoculating of T. harzianum four days after F. subglutinans inoculation. The results of this research showed that Trichoderma harzianum is effective to inhibit the growth of F. subglutinans in planta. The mechanism of T.harzianum to inhibit the growh of F.subglutinans is by nutrient competition.

Abstract

Pinus radiata is the major softwood species planted in New Zealand and Australia. Endophyte fungi that have been extensively studied in conifers needles mainly based on fungal isolation and also rarely conducted in Pinus radiata. This study aimed to observe the optimum condition of P. radiata needles sample for direct extraction of fungal DNA and to identify the fungi associated with P. radiata needles in Plenty plantations by a direct PCR approach. Room temperature dried needles produced clear and consistent DNA amplification compare to fresh needles, and needles dried on drying room or drying machine. Capnodiales was the most diverse group and no fungal pathogen detected in this study. DNA sequence data from direct DNA extraction of P. radiata needles provided sufficient discrimination and identification of fungal species.
