“…and also has the potential to act as a biological agent (Suswanto et al 2018), in addition to absorbing chromium, and is, therefore, suitable for processing waste containing hexavalent chromium (Vinay and Dwivedi 2019) and increasing tomato's resistance to blight (Abdel Motaal et al 2020). Reports by Berg and Hallmann (2006), as well as Sucipto et al (2015) show endophytic fungi's mechanism of direct inhibition against pathogens is through antibiosis, competition, as well as lysis, while the indirect mechanism involves inducing plant resistance and increasing plant growth. However, the endophytic fungi tested in this study need to be tested for tobacco plants' pathogenicity.…”

Abstract. Syamsia S, Idhan A, Firmansyah AP, Noerfitryani N, Rahim I, Kesaulya H, Armus R. 2021. Combination on endophytic fungal as the Plant Growth-Promoting Fungi (PGPF) on Cucumber (Cucumis sativus). Biodiversitas 22: 1194-1202. Endophytic fungi are known to stimulate plant growth by producing secondary metabolites, including phytohormones (IAA and Gibberellins), siderophore, phosphate-solubilizing metabolites. In this study, a total of six endophytic fungi were successfully isolated from local rice plants and showed different abilities in producing secondary metabolites, during single isolates testing. These six isolates were then combined to obtain 15 combinations for analysis, to determine the best combination for application as a plant growth promoter. Subsequently, each combination was tested for phytohormones (IAA, gibberellins) and siderophore (quantitatively)-producing activity, phosphate-solubilizing ability, and the effect on cucumber (Cucumis sativus L) plant growth. F13 showed activity in producing IAA and produced the highest gibberellin levels, while F1 exhibited the highest phosphate-solubilizing activity. In addition, F11 (Na-salicylate) and F1 (catechol) showed the highest siderophore activity, while a combination of F6, F8, F9, and F12 successfully increased plant height growth. Also, F4 increased the root growth, while the fresh weight of cucumber was increased by F8 treatment, under controlled conditions. Molecular analysis showed the tested isolates have close similarity to Daldinia eschscholtzii, Sarocladium oryzae, Rhizoctonia oryzae, Penicillium allahabadense, and Aspergillus foetidus. The combination of endophyte fungal isolates showed potential as plant growth promoters, however, further testing on several plant types is required before the combination is to be widely applied.

Rice is a staple food crop for some Indonesians. To increase rice production, various efforts have been made, one of which is seed priming using biofertilizers. Biofertilizer or biological fertilizer uses microorganisms that are used as plant growth boosters. The microorganisms used to act as PGPF (Plant Growth Promoting Fungi) are Trichoderma spp. Trichoderma spp. widely used because it can trigger plant growth. This study aims to determine the response of Trichoderma spp. to the seed vigor index and dry weight of rice sprouts of sirandah batuampa variety. The research method is experimental research using a completely randomized design (CRD) with 6 treatments and 3 replications. Parameters observed were seed vigor index and sprouts dry weight. The results showed that Trichoderma spp. had no significant effect on seed vigor index and sprouts dry weight. Judging from the mean value, the seed vigor index of SBT, SRBA, and KRT had better values than the control, as well as the dry weight of sprouts with the provision of SBT, SRBA, and SB isolates. This shows Trichoderma spp. This gave a positive response to the Sirandah Batuampa variety.

Application of fungicides to control rice diseases potentially have adverse effect on non target organisms including endophytic fungi. Unfortunately, information of fungicide effect on endophytic fungi on rice is still limited. The purpose of this research was to study the diversity and abundance of endophytic fungi on rice plant because of application of synthetic fungicides. There were two treatments in this study: non systemic fungicide (mankozeb) and systemic fungicide (difenoconazole) which were compared to control (without fungicide). Isolation of endophytic fungi and application of fungicides were conducted every week started at aged of 3 to 10 weeks after planting. Variables observed were total segment of rice colonized by endophytic fungi, colonization frequency of endophytic fungi, continued by identification and analysis of the diversity of endophytic fungi. This study showed that there was an increase in colonization of endophytic fungi with an increase of plant ages. The diversity of endophytic fungi was higher in stems than in leaves with the value of H' is 0.00-1.35 and 0.00-0.98 respectively. The most common types of endophytic fungi appear in each isolation of rice segments were Acremonium, Curvularia, Fusarium, Helminthosporium, Nigrospora, Penicillium, and Mucor. Both fungicides do not significantly affect the percentage of colonization and diversity of endophytic fungi. At the beginning of planting (4-6 MST) there was a decrease in the percentage of endophytic fungal colonization in the stem. From the percentage of colonization of each genus of fungi, Nigrospora and Fusarium decreased significantly with difenoconazole on the stem during the vegetative phase. Keywords: colonization, community, difenoconazole, diversity, mancozeb
