“…Bakteri pemacu pertumbuhan dapat bereaksi secara langsung dalam tanaman dengan menghasilkan fitohormon, vitamin, atau molekul organik yang mudah diserap oleh akar, atau secara tidak langsung melalui ameliorasi hara mineral dengan cara pelarutan dan mineralisasi unsur hara tertentu. Farida et al (2018) menyatakan bahwa aplikasi bakteri penghasil IAA yang telah ditemukan dapat dicampur dengan tanah gambut untuk menanam benih tanaman. Bakteri dalam tanah tersebut dapat menempel pada akar kecambah, kemudian memanfaatkan eksudat akar berupa triptofan untuk menghasilkan IAA.…”

Pineapple (Ananas comosus L. Merr) is a plant that can live well on nutrient-poor lands such as peatlands. However, plant resistance to nutrient-poor conditions is caused by symbiosis with endophytic bacteria capable of plant growth-promoting bacteria (PGPB) through biostimulant and bioprotective mechanisms. This study aims to characterize the potential of endophytic bacteria from pineapple roots from peatlands as biostimulants and bioprotective agents. Thirteen endophytic bacteria from pineapple root were characterized by their ability as biostimulants through phosphate dissolution tests using Pikovskaya media qualitatively and quantitatively, and the production of indole-3-acetic acid (IAA) upon additional 0.1% tryptophan. Furthermore, bacteria as bioprotectors were characterized by qualitative production of chitinase enzyme and antifungal tests against Fusarium proliferatum using dual culture techniques. The results showed the presence of 2 positive bacteria in all tests, namely the ANAP3 and ANAP5 isolates. ANPA3 bacteria show the highest activity in IAA production (26.3 ppm), and the highest antifungal activity in inhibiting F. proliferatum, with an inhibitory index reaching 52.6%. Meanwhile, ANAP5 is an endophytic bacterium with the highest phosphate dissolving activity, with a dissolved phosphate value of 253.5 ppm. This finding shows that some endophytic bacteria from pineapple roots on peatlands can be biostimulants and bioprotectors that can be developed as PGPB. Keywords: Ananas comosus L. Merr, endophytic bacteria, bioprotectant, biostimulant, Fusarium proliferatum

“…Indole Acetic Acid (IAA) is the most widely used auxin growth regulator which functions in stimulating cell division, differentiation of transport tissue, cell elongation, and root initiation (11). The addition of auxin to potato seeds resulting from tissue culture will accelerate the growth and length of plant roots.…”

The provision of quality potato seeds is a problem faced by farmers. Tissue culture propagation is an effort to increase the availability of quality seeds. The success of tissue culture is influenced by the ability to control environmental conditions, growth regulators, and growing media at the acclimatization stage. The research aims to determine the interaction between the use of auxin concentrations and the planting medium and to obtain the appropriate concentration of auxin and planting medium for potato acclimatization. The research used a split-plot design with 2 factors and 3 replications. The main plot is the auxin concentration consisting of 3 levels; 1 ppm, 2 ppm, and 3 ppm. Subplots are planting media consisting of 3 levels; husk charcoal:vermicompost, cocopeat:vermicompost, and husk charcoal:cocopeat:vermicompost. Data were analyzed using ANOVA and followed by DMRT at a 5% level. The results showed that there was an interaction between the treatment of 3 ppm IAA concentration and the planting medium of husk charcoal:cocopeat:vermicompost on the plant height parameter 4 WAP. The IAA concentration of 3 ppm was better than the concentration of 1 ppm in the parameter number of leaves 8 WAP. The growing media of husk charcoal:cocopeat:vermicompost was better than the growing medium of charcoal husk:vermicompost on the parameters of plant height 8 WAP, number of leaves 8 WAP, leaf length and leaf width 8 WAP.
