Abstract

AbstractGanoderma is a pathogen cause rot root desease which attack the plant with a wide range of ages. It is necessary to do research to know level of acacia plant resistance at 1 month and 3 months on Ganoderma infection. The research aims was to determine the effect of Ganodermainfecton on acacia resistance at the age of 1 month and 3 month. The research used a factorial completely randomized design which consist of two treatment factor namely Ganoderma and age of seedling. Ganoderma treatment is control (G0), Ganoderma from palm oil (G1), Ganoderma from the acacia host (G2), Ganoderma from the rubber host (G3). The age treatment of seedling is 1 month acacia seedlings and 3 month acacia seedlings. Each treatment was repeated 3 times with 4 plants per replication resulting in 96 experimental units. Research observation variable is desease severty index by in vivo and dry weight of the plant. The result showed Ganoderma is pathogenic in 1 month acacia seedling with a severity index value of 0,6 and 3 month acacia seedling with a severity index value of 1. Dry weight of plant control treatment of acacia seedling age 3 months higher than other treatment that is 11,27. 3 month old acacia seedlings are more susceptible and rapidly cause symptoms of Ganoderma infection than 1 month old acacia seedlings. Keywords: Acacia mangium seedling, Ganoderma sp., In vivo Infection

Abstract

Trembesi is a fast growing species and has a high resistance to the environment and can be harvested within a short period of planting rotation of 5-8 years. This type was chosen because it has a unique texture, besides that this tree is believed to be able to contribute to tackling air pollution and the threat of global warming. Trembesi is also a tree that is an alternative that can be cultivated extensively for the purpose of rehabilitating marginal lands. However, the supply of healthy and quality trembesi seeds is still constrained by the presence of destructive pest insects. This study aims to identify pest insects that attack trembesi seedlings and determine the level of damage caused by pest insects by using calculations based on the types of visible damage, in the permanent nursery area of Kapuas City of Pontianak. The method used in this study is the census method with direct observation of trembesi seeds in the nursery. The results of the study stated that there were 5 types of insects which were thought to attack trembesi seeds, in the nursery area there were 5 types which included cone grasshopper (Tagasta marginella), Small grasshopper (Oxya sp.), Woodhopper (Valanga nigricornis). the Hemiptera order includes the walang sangit (Leptocorisa acuta). caterpillar tritip (Plutella sp.), The results showed an average percentage of damage caused by insect pests was 34.02% and the percentage level of damage was 22,02% of the total seedlings of 2,880 seeds observed and included in the category of minor damage. Although including the category of minor damage, it is necessary to further improve cleaning in the environment around the nursery area so that it can reduce the potential percentage and damage to the seedlings.Keywords: Identification, insects, level of destruction, pests, trembesi seedlings

Abstract

Development of pink disease on the various ages of Acacia crassicarpa Cunn Ex. Benth.. The increase in the value of pulpand paper exports in Indonesia is partly due to the development of industrial forest plantations of acacia on peatlands. Acaciacrassicarpa grows well on peatlands with high productivity. However, the development of pink disease is a threat to thegrowth of A. crassicarpa, both in the nursery and in the field. This study aimed at examining the development of pink diseaseon the various ages of A. crassicarpa. The study was conducted using census method on plants at aged 4, 24 and 42 months.Variables observed were symptoms, incidence, and severity of disease. Data were analyzed descriptively and regressively tounderstand the relationship between the incidence and severity of the disease and the age of the plant. The results showedthat the symptoms that appearing at the seedling level were similar to those the sapling, poles and tree level. The presence ofthin colonies of cobweb-like (cobweb stage), mycelia aggregation from the cobweb stage (pseudonodular stage), and theappearance of pustules and pink incrustation (teleomorph stage) were common symptom. However, disease incidence andseverity were moderate at the seedling and mild at the saplings, poles and trees level. The incidence and severity of diseasedecreased with increasing age.

Abstract

Research on the induction of the sapwood of agarwood has been extensively studied, but this has not yet resulted in the dept standard of hole of inoculation and the diameter of trees in order to produce the best sapwood. Therefore, this study aimed to study the depth of the effective inoculation hole to accelerate the formation of agarwood cambium or sapwood in various tree diameters, and to know the interaction of agarwood induction. This research was conducted in Sekadau Hilir district. The design of this research was a nested method. The treatment consisted of tree diameter (i.e., 11.46 cm, 16.56 cm, and 24.20 cm) as the main factor, while the depth of the inoculation hole (i.e., 1 cm, 2 cm, 3 cm, 4 cm, and 5 cm) was the second nesting factor. The hole spacing was 15 cm, which was in each treatment, the depth of the inoculation hole was repeated 5 times. The number of holes consisted of 75. In which the depth of inoculation hole was 3 cm producing an infection on area of 485.13 cm2, brown, and with strong aroma. Tree diameter of 11.46 cm produced 872.92 cm2 of infected area, blackish brown, and with strong aroma. However, the interaction of tree diameter and the dept of hole was not significant toward the area of agarwood infection formed.Keyword: Agarwood, Aquilaria malaccensis, inoculation

Abstract

Mangosteen is an annual plant whose vegetative growth such as roots, stems and leaves runs very slowly. To spur the growth of mangosteen used biological agents Trichoderma sp. and Arbuscular Mycorrhizal Fungi. The combination of Trichoderma sp. and FMA can accelerate plant growth, root development, and increase nutrients, but not yet known when the inoculation of Trichoderma sp. which is effective on morphorous soils that can increase the growth of mangosteen plants. This study aims to obtain the infuence of inoculation time Trichoderma sp. and Arbuscular Mycorrhizal Fungi (FMA) are effective in improving the growth of mangosteen seeds. This study was designed in RIL (Completely Randomized Design) with the treatment : without Trichoderma and FMA (W0), FMA inoculation without Trichoderma (W2), Trichoderma inoculation together with FMA (W3), Trichoderma inoculation 3 days after inoculation of FMA (W4), and Trichoderma inoculation 7 days after inoculation of FMA (W5). Each treatment was repeated five times so that there were 30 experimental units. The observed variables were height (cm) and plant diameter (mm), number of leaf buds, and FMA colonization at root (%). Maintenance conducted is watering and weeding. The results showed that the parameters of treatment time of inoculation Trichoderma sp. and Arbuscular Mycorrhizal Fungi have no significant effect on the growth of height, diameter and number of leaf buds. This is because the research time is relatively short. Therefore, the need for further research with a longer period of time.Keyword: Arbuscular Mycorrhizal Fungi (FMA), Diameter, Garcinia mangostana L, High, Leaf bud, Trichoderma sp.
