Abstract

The aim of this research is to determine and analyze the ability of agarwood plants to grow on inceptisol soil and to analyze the factors that determine the growth of agarwood plants on inceptisol soil in Hatusua Village, Kairatu District, West seram Regency. The method used in this research is a completely randomized design method, the data collection technique used in this research is in the form of direct observations carried out on a demonstration plot of the source of agarwood (Aquilaria malacccensis lamk) seeds from which 3 trees were taken from each provenance. And data analysis used a completely randomized design and multiple regression analysis. The results obtained from the research were variance analysis of parameters which showed that only the leaf bones were real. The three provenances are determined by three soil factors, namely fertility, humidity and pH. Of the three soil factors, only Laimu provenance has an influence, because it has a larger F-value. And the environmental factor that has the most influence on the Laimu provenance is atmospheric humidity, while the environmental factor that has the most influence on the Mornateng provenance agarwood plant is soil moisture and the most influential environmental factor for the Passo provenance agarwood plant is light intensity.

Abstract

Bacterial exploration aims to find out how endophytic bacteria associate with the roots of samama plants and find out the morphological characteristics of the endophytic bacteria found. So we can determine the type/family of endophytic bacteria on the Samama plant. Sampling of samama plants (Anthocepalus macropyllus) was taken on the campus of the Faculty of Agriculture, Pattimura University. The parts of the plant samples taken were roots, bark, leaf twigs and leaves. The number of tree samples taken as examples was 3 individual trees. Each plant organ sampled is 200 gr. The data analysis method used is by adjusting the data resulting from the identification of macroscopic and microscopic characteristics with the characteristics of bacterial families that are available according to references. Based on the results of this research, it can be concluded that: there are 9 isolates of endophytic bacteria, namely KB1 KB2 KB3 KB4 A1 A2 A3 A4 and B1 in the root, stem and bark tissues of Samama plants. Endophytic bacterial isolates Kb1, Kb2, kb3, kb4, A2, A4 have similar characteristics to the bacterial group of the genus Bacillus with the characteristics of rod-shaped cells and are classified as gram positive, while isolates Kb4, A2 and A4 have the characteristics of the genus Bacillus and have rod-shaped characteristics and classified as gram negative. Then isolate A1, A3, B1. It has similar characters to members of the coccus genus, namely round cells and is classified as gram positive, but the isolate code is classified as gram negative. The results of biochemical analysis show that samama plants have 3 types of bacteria, namely Bacillus altitudinis, Bacillus pumilus and Bradyrhizobium sp.

Abstract

Provenance testing is one of the tree breeding approaches to obtain quality seeds, a testing process is needed to find better seed sources in the development area. In this case the species chosen is Agarwood (Aquilaria malaccensis). The aim of this research is to understand the differences in growth of two provenances of gaharu plants (Aquilaria malaccensis) from Ambon Island Village and Laimu Village, Seram Island. This research took place in December 2022 and was carried out in the 2 year old Agarwood Plant Genetic Resources Area (Aquilaria malaccensis), in Hatusua Village, Kairatu District, West Seram Regency. Research shows that of 400 agarwood plants originating from Passo Village, only 309 survived and 91 died, so the percentage of surviving plants reached 77%. Meanwhile, for Laimu Village, of the same 400 plants, there are 315 that are still alive and 85 that are dead, so the percentage of living plants in Laimu Village is 79%. Based on this analysis, the calculated t-value is 2.16, while the t-table at α = 0.05 with 39 degrees of freedom is 2.02. This shows that the t-count is greater than the t-table, which indicates there is a significant difference between the provenances of Passo Village and Laimu Village. For plant diameter, the t-count was recorded at -0.21, and when compared with the t-table at α = 0.05 and 39 degrees of freedom which is 2.02, the t-count is smaller than the t-table. Therefore, there is no difference in diameter between the two provenances.
