Abstract

The research investigated the influence of four isolates of arbuscular mycorrhizal fungi(AMF) on the growth of duku seedlings. The research used randomized block design with onefactor of some isolates AMF: Glomus-sp 3, 6, 15, and 16 at a dose of 20 g per polybag. The resultsshowed that inoculation of AMF isolates increase the canopy and root growth of the dukuseedlings. Duku seedlings inoculated with mycorrhiza showed higher plant height, stem diameter,dry weight, secondary roots number and length, than the control. Furthermore, mycorrhizalinoculation increased the absorption of nutrients (Phosphor) in the leaves of duku seedlings. Rootstaining results showed that AMF colonization in the duku roots only indicate hyphae; the otherstructures (vesicles, arbuscular and spores) were not detected.

Abstract

Coffee is one of the strategic plantation commodities that has high economic value and an important role in the national economy. Among the various types of coffee cultivated in Indonesia, Coffea liberica has great development potential, especially in areas such as Jambi Province. However, conventional propagation of Liberica coffee plants through seeds orcuttings still faces obstacles, such as low success rates and slow growth rates. Therefore, tissue culture techniques are an alternative solution to produce Liberika coffee seedlings in bulk, quickly, and uniformly. This study aims to optimize the effect of growth regulator (ZPT) concentration interaction of auxin (2,4-D) and cytokinin (BAP) on liberica coffee callusformation in vitro. Experiments were conducted at the Plant Biotechnology Laboratory, Jambi University, using a factorial completely randomized design (CRD) with two factors. The first factor is the concentration of 2,4-D which consists of two levels, namely 1 ppm (d1) and 2 ppm (d2). The second factor is the concentration of BAP which consists of five levels, namely 1 ppm (b1), 2 ppm (b2), 3 ppm (b3), 4 ppm (b4), and 5 ppm (b5). Parameters observed included color, structure, size, and callus weight after 12 weeks of culture. The results showed that the interaction between 2,4-D and BAP significantly affected all observation parameters. Callus with the highest size (2.66 cm) and weight (2.90 g) were obtained in the combination of 1 ppm 2,4-D + 4 ppm BAP and 2 ppm 2,4-D + 1 ppm BAP respectively. The callus was yellowishwhite to green and had a crumbly or compact structure, depending on the ZPT combination. In conclusion, a balanced combination of ZPT concentrations greatly determines the success of Liberika coffee callus proliferation, and the results of this study provide an essential basis for the development of efficient coffee tissue culture.

Abstract

The objective of this research was to assess the response of Jatropha curcas to indigenous Arbuscular Mycorrhizal Fungi (AMF) and P fertilizers applications in former coal mine fields. This study used a single factor Randomized Block Design which is a combination of mycorrhiza and P fertilizer consisting of 10 levels (without FMA and without P fertilizer, without FMA and 25% recommended doses of P fertilizer, without FMA and 50% recommended doses of P fertilizer, without FMA and 75% recommended doses of P fertilizer, without FMA and 100% recommended doses of P fertilizer, FMA and without P fertilizer, FMA and 25% recommended doses of P fertilizer, FMA and 50% recommended doses of P fertilizer, FMA and 75% doses of P fertilizer, FMA and 100% recommended doses of P fertilizer), with recommended doses is 150 Kg SP 36 / ha The observed variables were N, P, K uptake and Jatropha curcas yield. The results showed that the symbiotic of Jatropha curcas with FMA combined with 50% recommended dose of P fertilizer gave the best N, P, K uptake and Jatropha curcas yield in Coal Post-Mining Land.

Abstract

The aim of this research was to obtain the mycorrhizae type and rootstockheight which was able to increase the grafting success, the growth and P uptake of grafted robusta coffee seedlings. This experiment is a two-factor factorial experiment using a completely randomized design of three replications. The first factor was mycorrhizal inoculation consisting of six levels, namely without mycorrhizal inoculation, inoculation of Glomus sp-3, Glomus sp-6, Glomus sp-15, Glomus sp-16, and mixed of Glomus sp-3, sp-6, sp-15, sp-16. The second factor is the rootstock height which consists of five levels, namely 5, 10, 15, 20 and 25 cm from base of the root. The results showed that the best growth and P uptake of grafted robusta coffee seedlings on various types of mycorrhizae were obtained at a 15 cm from the root baserootstock height. The growth and P uptake of grafted robusta coffee seedlings at rootstock heights obtained in the mixed ofGlomus sp-3, sp-6, sp-15, sp-16. The grafting success of the mycorrhizal grafted robusta coffee seedlings is 100% and the without mycorrhizal grafted robusta coffee seedlings are 79.87%, while at various rootstock heights ranges from 95.83 to 97.22%.
