Abstract

Priming benih merupakan perlakuan pada benih sebelum tanam dengan hidrasi terkontrol yang mampu meningkatkan perkecambahan. Salah satu ekstrak ekstrak yang berpotensi untuk dimanfaatkan sebagai bahan priming adalah paku (Davallia denticulata). Penelitian ini bertujuan untuk mengetahui jenis pelarut ekstrak dan konsentrasi terhadap perkecambahan benih cabai (Capsicum annum L.). Metode yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap Faktorial dua faktor yang terdiri dari 3 ulangan, dilaksanakan bulan Agustus 2024. Penelitian ini dilakukan di Laboratorium Teaching 4, Jurusan Biologi, Universitas Andalas. Perlakuan terdiri dari jenis pelarut, a1 (aquades), a2 (metanol), a3 (etanol), dan a4 (butanol). Faktor kedua konsentrasi ekstrak paku kaki tupai, b0 (0 ml/l), b1 (25 ml/l), b2 (50 ml/l), dan b3 (100 ml/l). Hasil penelitian menunjukkan bahwa priming dengan jenis pelarut berpengaruh terhadap daya kecambah, kecepatan tumbuh, indeks vigor, panjang akar, dan berat basah kecambah. Konsentrasi ekstrak paku berpengaruh terhadap daya kecambah, kecepatan tumbuh, indeks vigor, panjang akar dan berat kering kecambah.

Abstract

Ferns are a potential source of biostimulant compounds due to their rich content of bioactive secondary metabolites. This study aimed to evaluate different solvents for extracting bioactive compounds from Davallia denticulata and to identify the optimal extract formulation for enhancing the growth and yield of Kopay chili. This research was conducted from February to May 2024 at the Plant Physiology Research Laboratory and Greenhouse, Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Andalas, Padang. A completely randomized design with 16 treatment combinations involving four solvents (A1 = aquadest, A2 = methanol, A3 = ethanol, A4 = butanol) and four extract concentrations (B0 = 0 mg L-1, B1 = 25 mg L-1, B2 = 50 mg L-1, and B3 = 100 mg L-1) was employed. Plant growth parameters responded differently to various combinations of extract concentration and solvent type. Methanol extract at 100 mg L-1 significantly increased plant height, ethanol at 50 mg L-1 improved shoot dry weight and root biomass, butanol at 100 mg L-1 increased chlorophyll b and total chlorophyll, and methanol at 25 mg L-1 resulted in higher fruit weight. These results indicate that Davallia denticulata extract, when properly formulated, holds strong potential as a natural biostimulant to improve growth and productivity in chili cultivation.

Abstract

Dendrobium mussaense, an orchid species of high ornamental value, was subjected to experimental treatments involving the addition of combinations of auxin and cytokinin, namely 2,4-D (2,4-dichlorophenoxyacetic acid) with BAP (6-benzylaminopurine) and 2,4-D with TDZ (thidiazuron). The research aim was to evaluate their effects on the emergence time of shoots and roots. The method used an experiment design with seven treatments. Among the treatments, the most effective was 2,4-D at a concentration of 1 mg/L combined with 0.75 mg/L of BAP. This treatment resulted in the shortest time for both shoot and root emergence. These findings underscore the importance of optimizing hormone combinations for efficient shoot and root induction in D. mussaense, providing valuable insights for orchid propagation and cultivation practices.

Abstract

Cytokinins are growth regulators that play a crucial role in cell division and shoot growth. Thidiazuron, a potent cytokinin, was the focus of our research. The research aimed to determine the effect of several concentrations of Thidiazuron on the protocorm growth of Grammatophyllum stapeliiflorum and to identify the best concentration of Thidiazuron (mg/L) for the protocorm growth of G. stapeliflorum orchids in vitro. The research was conducted from January until March 2022 at the Plant Physiology Laboratory, Universitas Andalas, Padang. The research used a Completely Randomized Design (CRD) with 5 treatments and 5 replications. Several concentrations of Thidiazuron were added to MS media with various concentrations: 0 mg L-1 (A), 0.50 mg L-1 (B), 1 mg L-1  (C), 1.50 mg L-1(D), and 2 mg L-1  (E). The parameters in this research were the percentage of life explants, day of shoot appearance, number of shoots, shoot length, number of leaves, number of roots, and root length. The results showed that Thidiazuron significantly affected the protocorm growth of the G. stapeliiflorum orchid compared to the control treatment. Notably, 2 mg L-1  Thidiazuron emerged as the best concentration for all growth parameters of protocorm G. stapeliiflorum, a finding that could significantly impact our understanding of orchid cultivation and plant physiology.
