Abstract

ABSTRACT Mangrove is a typical tropical and subtropical forest plant, grows along the coast or river estuary and affected by the ebb and ride of the sea. The ebb is a factor that determines the distribution of mangrove forest. Almost all mangrove plants have floating seeds, and this results in its easy dissemination by the water to the back of the forest. The purpose of this study is to comprehend the relationship between type of the plats distribution with the tidal wave if the mangrove forest of Teluk Buo, in the district of Bungus / Teluk Kabung, in the city of Padang . This descriptive study was performed during June-July 2013. Samples were collected from two research transection. In the location two transections were created at the lengths of 160 m and 180 m perpendicular to the shore lines toward the forest. Each transection consisted of 16 and 18 observation plots with the size 10 m by 10 m each, with the distance between transections at 100 m to better represent the forests vegetation. The result shows that in the mangrove forest of Teluk Buo there are seven types of mangrove plats, those are Rhizophora apiculata, Sonneratia caseolaris, Aegiceras corniculatum, Acanthus ilicifolius, Bruguiera gymnorrhiza, Dolichandrone spathacea, dan Hibiscus tiliaceus. The height of ebb-tide waves has big influences on the distribution of the plants types. The distribution successively from the shore line to the back of the forest are Rhizophora apiculata, Sonneratia caseolaris, Aegiceras corniculatum, Bruguiera gymnorrhiza, Dolichandrone spathacea, Acanthus ilicifolius, and Hibiscus tiliaceus. The type with the broadest distribution at the highest tide is Rhizophora apiculata.

Abstract

Biological control or biocontrol is a way that involves organisms to reduce the growth of pathogens and reduce the impact of disease. The use of biocontrol agents is an alternative to control plant disease-causing pathogens. One of the biocontrol agents that can be used is Pseudomonas fluorescens. Basically P. fluorescens is the largest group producing antibiotics and antimicrobial compounds of cyanide acid (HCN) and siderophores. The compounds it produces can inhibit activity and control pathogens. Therefore, P. fluorescens has great potential as a biocontrol agent for controlling plant diseases. This study aims to collect and analyze articles related to P. fluorescens as a biocontrol agent for controlling various plant diseases. This type of research is research that uses internet sources from the Google Scholar database. The stages consist of identification, screening, eligibility and acceptance. Based on the articles collected, it was found that P. fluorescens is a biocontrol agent that can control various plant diseases. Biocontrol agents influence the activity and growth of pathogens thanks to the compounds they produce

Abstract

Data is needed regarding the structure and status of natural regeneration in the Maninjau Nature Reserve Conservation Forest which will be carried out from December 2022 - January 2023. The tools and materials used are labels, raffia rope, plastic bags, stationery, hygrometer, thermometer, lux meter, stake , meter, camera and GPS, carried out in 2 different places, namely natural areas and open/damaged areas. The sample plots used were nested square plots measuring 20x20m, ie 2x2m for the seedling phase, 5x5m for the sapling phase, 10x10m for the pole phase, and 20x20m for the tree phase. In each area 3 plots were placed randomly. Data is processed to obtain vegetation data and analysis of regeneration status. Plants found in natural areas at the seedling level are 12 species, 8 species for saplings, 4 species for poles and 11 species for trees, in open areas for seedlings 10 species, 5 species for saplings, 3 species for poles and 5 species for trees. Overall regeneration status can be said to be good because 7 species (35%) regenerate well, 2 species (10%) have sufficient regeneration, 6 species (30%) have low regeneration and 5 species (25%). In open/damaged areas it has a low regeneration density.
