Abstract. Usman AHA, Hartoyo APP, Kusmana C. 2022. The growth performance of Rhizophora apiculata using the cut-propagule method for mangrove rehabilitation in Indonesia. Biodiversitas 23: 6366-6378. A high decrease in the size of Indonesia's mangrove forests requires effective and efficient rehabilitation efforts. One of the efforts is using Rhizophora apiculata as the adaptive and fast-growing mangrove species and its cut-propagule seedling method for accelerating plant propagation. The objectives of this study were to analyze the growth performance of R. apiculata propagules with various treatments of propagule cutting, seedling media, and giving growth regulators (PGR), as well as to determine the best combination of treatment for the growth of R. apiculata. An experimental study was conducted in a greenhouse using a randomized design with 3 factors (propagule cutting, seedling media, and giving PGR) and 3 replications. The interaction of the combination of cut-propagule treatment, planting media, and growth regulator (AxBxC) only had a significant effect on the increase in the number of leaves of R. apiculata. Complete propagules and the lower part of cutting propagules with a combination of mud+sand seedling media and 10,000 ppm PGR (a0b1c1 and a2b1c1) resulted in the best value on the growth of R. apiculata. The cut-propagule seedling method of R. apiculata still showed good growth so it can be used as an alternative to mass vegetative reproduction in mangrove rehabilitation activity.

Abstract

Abstract. Nugraha LA, Kusmana C, Hartoyo APP. 2024. The growth performance of Kandelia candel hypocotyl cuttings seedlings for mangrove rehabilitation in Indonesia. Biodiversitas 25: 2683-2695. Kandelia candel (L.) Druce is one of the mangrove species threatened with extinction and continues to decline in number yearly in Indonesia. Effective and efficient propagation techniques are urgently needed to reduce the risk of extinction and accelerate the rehabilitation of this mangrove species. This study aimed to analyze the growth performance of K. candel hypocotyl cuttings and determine the best combination treatments. The type of this study was experimentally carried out in a greenhouse. The experimental design was a completely randomized three-factor factorial design with three factors and three replications for each factor: hypocotyl cuttings, planting media, and growth regulators. Based on the variance test resulted in the interaction between the hypocotyl cutting, planting media, and plant growth regulator had a significant effect on seedling height, number of leaves, total weight biomass, sturdiness quotient, and Dickson Quality Index at the 5% test level. The experiment was a success, with all combinations of treatments showing a survival rate of 100%. The best growth of hypocotyl cuttings was found by combining the bottom part of hypocotyl, mud + sand planting media, and a plant growth regulator of 15,000 ppm. The hypocotyl-cutting method can be an alternative method to provide quality seedlings for mangrove rehabilitation activities.
