Abstract

The research was to obtain information about the combination of fertilizers in the production of arbuscular mycorrhizal inoculums of various depths. This research is using an experimental method. The research uses divided plot design (RPT) with a basic RAK pattern. The treatment factor consists of the main plot (peat depth 0-50 cm and 50-100 cm) and subplot is a combination of fertilizer (P1 = without fertilizing; P2 = NPK+rubberwood vinegar; P3 = NPK+peat vinegar; P4 = NPK+fern-root vinegar). Spore breeding process is ± 3 months. Hosts use sorghum with sterile sand media. The observation variable consisted of the percentage of root infections and the number of spores. Data analysis using ANOVA. Identification of spores based on morphology and Melzer reaction. The results showed that fertilization factors affected the number of spores. The number of spores without fertilization was higher, namely 1642,500 spores compared to combination fertilizers (NPK+fern-root vinegar was 707,667 spores; NPK+rubberwood vinegar was 606,833 spores; NPK+peat vinegar was 206,667 spores). The rate of 0-50 cm colonization without fertilization, NPK+peat vinegar, NPK+rubberwood vinegar is included in the high category. Then in the treatment at 50-100 cm without fertilizing, NPK+peat vinegar, NPK+fern-root vinegar infection rates are also high. The type of spore found is Glomus sp.1; Glomus sp.2; Glomus sp.3; Glomus sp.4. The results of the number of spores and the percentage of root infections showed that organic vinegar was known to not stimulate FMA sporulation, but organic vinegar did not inhibit FMA colonization.Keyword: Mycorrhizal, organic vinegar, peat depth, sorghum

Abstract

A river-sand culture experiment was conducted to investigate whether arbuscular mycorrhizal (AM) colonization influenced mercury (Hg) and nutrients accumulation, and whether AM fungus (AMF) Gigaspora margarita enhance host plant sengon buto (Enterolobium cyclocarpum) tolerance to Hg. Hg was applied as HgCl2 at different levels (375 and 750 µM) and added to the full strength of Hoagland's solution, then applied to seedlings in river-sands as growth media according to treatments.  The non-mycorrhizal and mycorhizal E. cyclocarpum roots took up Hg, but its translocation to the leaves was inhibited. AM inoculation decreased significantly Hg content of roots seedlings by 70.5% from non-AM inoculation seedlings. Mycorrhizae enhanced significantly Ca and Mg uptake in shoot by 1.29- and 1.27-fold higher than non-mycorrhizal seedlings, but not enhanced significantly P uptake. Based on the roots dry weight, the tolerance index of non-mycorrhizal or mycorrhizal seedlings treated with 750 µM Hg supply was > 50%. It indicated that the seedlings can tolerate up to 750 µM Hg added. Considering the possible differences in AMF response to Hg in polluted soil from the field, it is not yet clear if Gi. margarita could be applied for phytoremediation of Hg in contaminated sites. Therefore, more work needs to be done using AMF isolates to reveal the possible application in the management of Hg contaminated soils.

Abstract

Kembang telang leaf extract is antimicrobial controlling pathogenic fungi in vitro. The purpose of the study was to determine the ability of the kembang telang leaf extract as an inhibitor of the growth of fungi that cause root rot and the concentration of the extract that was most effective. The research was carried out in the Silviculture laboratory Faculty of Forestry Universitas Tanjungpura for three months. The experimental method used a completely randomized design with treatments consisting of four concentrations, namely 0%, 3%, 6%, and 9%, with three replications. Telang flower leaf extract can inhibit Ganoderma sp. An inhibition zone looks more apparent than the Telang flower leaf extract area. The growth of fungal growth at the lowest concentration of 3% is the same as effectively inhibiting the growth of Ganoderma sp. The research results imply that the flower telang leaf extract has the potential as an antifungal against the Ganoderma sp.      Keywords: antimicrobial, extract, Clitoria ternatea, Ganoderma.AbstrakEkstrak daun kembang telang memiliki efek antimikrob dalam mengendalikan jamur patogen secara in vitro.
