“…IAA is a highly important phytohormone for the formation and elongation of plant roots, root hairs, as well as lateral root, in order to increase both nutrients and air absorption as well as plant development (Mishra et al 2009;Ahmed and Hasnain 2010;Hussain et al 2013;Hagaggi and Mohamed 2020). Meanwhile, auxin also plays an important role in root formation (Casimiro et al 2001;Sapareng et al 2017), and the IAA produced by endophytic fungi has the ability to increase plant growth and productivity (Yuan et al 2010;Widowati et al 2016).…”

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.

Many taros (Colocasia esculenta var. antiquorum) grow in Sulawesi due to their large scale acceptability and high return per unit area, but their productivity is still low. In this study, fungi producing indol-3-acetic acid (IAA) were selected and characterized from the taro rhizosphere with the aim that it can be applied in stimulating the growth and production of this plant. By analyzing the content of IAA in the medium of fungi isolated, 12 fungal isolates were found producing this compound. The highest level of IAA is provided by isolate ETR 33 (8.89 ppm), ETR 29 (8.21 ppm), and ETR 5 (7.82 ppm). These isolates were identified as Fusarium, Trichoderma, and Aspergillus, respectively. These data that three strains of fungi were identified and characterized as the producer of IAA and potentially be used to develop a bio-fertilizer to increase the productivity of taro.
