Matoa, a Papuan fruit, is known to taste like a cross between longan, rambutan, and durian. Therefore, Matoa has seed storage and plant propagation restrictions. The tissue culture method of matoa propagation is used to solve this issue. This research aims to provide vegetative planting material that can be propagated in vitro. The study was conducted from June 2021 to January 2022 at the Laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Sebelas Maret University, Surakarta, using a completely randomized design pattern (CRD) 2x4 treatment factors for growth regulators. There were 16 treatment combinations, which were repeated three times. The first factor is Indole Acetic Acid (IAA) concentration, which has four levels: 0 ppm, 0.5 ppm, 1 ppm, and 1.5 ppm. The second factor is Benzyl Amino Purine (BAP) concentration, which has four levels: 0 ppm, 2 ppm, 4 ppm, and 6 ppm. The results revealed that root emergence time, leaf emergence time, root number, and leaf number all had high growth rates. The number of leaves and stem nodes correlated, indicating that matoa explant growth was linked.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
