Pterocarpus indicus Willd. also known as redwood is a native Philippine species belonging to the Fabaceae family that has many uses and high economic value and highly exploited. However, it is not accompanied by good regeneration which causes this species to be categorized as endangered (IUCN v. 2021-1). The in vitro technique is an alternative to overcome this problem. This study aims to determine the response of P. indicus Willd. shoot growth to the addition of BAP and TDZ in vitro. The research was conducted from August to December 2023, at the Biotechnology Laboratory, KST BJ. Habibie Puspiptek Serpong, South Tangerang, Banten. This study used a completely randomized design (CRD) consisting of 9 treatments and 14 replications. The treatments consisted of: R0 = Control, R1 = BAP 0,25 ppm, R2 = BAP 0,5 ppm, R3 = BAP 0,75 ppm, R4 = BAP 1 ppm, R5 = TDZ 0,25 ppm, R6 = TDZ 0,5 ppm, R7 = TDZ 0,75 ppm, R8 = TDZ 1 ppm. The results showed that the concentration of BAP 0,5 ppm gave the best results in height of shoot and TDZ 0,25 ppm gave optimum results in the number of shoots compared to the control and other treatment concentrations.

“…Hal tersebut diduga pada awal persemaian kebutuhan nutrisi tanaman masih disuplai dari cadangan makanan dalam propagul. Pernyataan ini diperkuat Safruni et al, (2019), yang menjelaskan propagul memiliki cadangan makanan berupa karbohidrat, protein, lemak, dan mineral yang bisa digunakan untuk mendukung pertumbuhan tanaman dalam menghasilkan energi benih saat perkecambahan.…”

Rhizophora mucronata is a mangrove plant that has the strongest root system and often chosen in mangrove forest rehabilitation. Planting Rhizophora mucronata often fails due to limited seed supply and poor seedling quality. This study aims to determine the growth response of Rhizophora mucronata propagules to coconut water immersion and NPK fertilizer. The research was conducted from February 2023 to June 2023 at the screenhouse of the Banten Agricultural Instrument Standardization Implementation Center (BPSIP) Banten. The research was arranged in a Randomized Group Design with three replications and consisted of two factors. The first factor is soaking treatment consisting of 2 levels, namely soaking without coconut water and soaking with coconut water. The second factor is the concentration of NPK fertilizer consisting of 4 levels, namely 0 g/plant, 9 g/plant, 12 g/plant, and 15 g/plant. The parameters observed were shoot emergence time (days), leaf emergence time (days), stem diameter (mm), number of roots (strands), and root length (cm). The results showed that coconut water soaking treatment gave results that significantly affected to stem diameter, number of roots and root length. The application of NPK fertilizer 9 g/plant gives results that significantly affected to shoot rupture time, leaf emergence time, number of roots, and root length.

“…"Narra", which is recommended as one of the trees in agroforestry provides shade to coffee and other crops and is adaptable in drought land areas [17]. This plant has ecological, industrial, and economic importance in Southeast countries due to its use in greening program, in medicine, in agroforestry, and as a source for natural dye, and furniture staff [18][19][20][21][22][23][24][25][26][27]. This plant has potential for phytoremediation of heavy metal compounds such as hexavalent chromium [28] or Cadmium [29].…”

Effects of Heavy Metal-Tolerant Microorganisms on the Growth of “Narra” Seedlings

et al. 2022

The effectiveness of heavy metal-tolerant microorganisms for supporting plant growth needs to be understood before it can be used as a soil bioremediation agent. The purpose of this study was to determine the effect of heavy metal tolerant microorganisms on the growth of “Narra” seedling (Pterocarpus indicus Wild). Three heavy metals-resistant (Pb, Cd, and Cu) rhizobacteria from a copper (Cu) mined-out site in Marinduque, Philippines showed plant growth promotion in vitro. A treatment combination of formula inoculant A (CuNFbM 4.1, MGR 333), B (CuNFbM 4.1, MGR 333, PbSM 2.1), and O (Uninoculated); compost (0%, 4%); and lime + inorganic fertilizer {without or with lime and inorganic fertilizer (LF0; LF1)} were applied to Narra seedlings planted on 445 mg/kg Cu-contaminated soil. Lime (2 mg/ha) and the recommended dose of soybean inorganic fertilizer were used as positive controls to evaluate the ability of inoculations and composts to promote the growth and used as positive controls to evaluate the ability of inoculants and composts to promote the growth and copper accumulation of narra in greenhouse experiments. All treatment combinations resulted in significant differences in plant height, leaf number, stem diameter, shoot and root dry weight, as well as, shoot, root Cu content, and plant Cu uptake of 13-week-old “Narra”. Inoculated “Narra” could thrive better in mine-degraded soil containing 445 ppm Cu with 4% compost. Inoculant B demonstrated the best plant performance while Pseudomonas synxantha (PbSM 2.1) probably increases the plant’s growth due to 1-aminocyclopropane-1-carboxylate (ACC) deaminase it produces. Accumulation of Cu was higher in the root compared other plant parts. More research is necessary to elucidate the mechanism of plant growth promotion and heavy metal re mediation by P. synxantha.
