Response to growth of mangrove seeds with additional extract of natural materials and vitamin b1 in the planting medium

Abstract

This study aims to determine the mangrove seedlings of Bruguiera sp, Rhizopora apiculata, and R. mucronata which have the best quality with the addition of extracts of natural ingredients, synthetic pgr and Vitamin B1. The study used 3 types of mangroves, namely Bruguiera sp., R. apiculata and R. mucronata, each consisting of 5 treatments; 100% shallot extract, 100% corn extract, Rhizattun F 0.1%, Vitamin B1 0.1% and water (control). The research used completely randomized Design (CRD). Parameters observed were number of leaves, plant height, number of roots and root length. Measurement of environmental factors includes pH and salinity. Data were analysed using Analysis of Variance (ANOVA) and continued with Duncan’s 5% test, if there was a significant difference. The results showed that the treatment of extracts of natural ingredients, synthetic pgr and Vitamin B1 resulted in varying effects on the growth of mangrove seedling. Treatment on Bruguiera sp, had a significant effect on root length with the control treatment having the highest length; while in R. mucronata, Rhizatun F treatment had a significant effect on the number and length of roots, while in R. apiculata the treatment given had no significant effect on the number of leaves.
