Perbandingan Morfologi Daun Kerai Payung (Filicium decipiens L.) di Universitas Negeri Padang dan Universitas Andalas

Abstract

Increasing the amount of vegetation or reforestation by planting trees is a solution in overcoming the problem of air pollution. Some of the criteria for plants that are able to accumulate pollutants are found in parasol sunshade plants. Direct contact of plants with air pollutant particles certainly affects plant leaves because the leaves will show phenotypic plasticity in response to abiotic stress. Therefore, research has been carried out on the morphological characteristics of parasol sunshade leaves as a greenery plant in the city of Padang. The study was conducted in September 2021. Samples were taken from two different locations, namely the Padang State University area and Andalas University. At each location samples were taken from 20 individuals and observations were made at the Botanical Laboratory, Department of Biology, FMIPA, Padang State University. Data were analyzed using t test with a significant level of 5%. The morphological characters of the parasol leaf in the Padang State University and Andalas University area showed significant differences in terms of leaf stalk length, number of leaflets in one petiole, number of leaf branches, and were not significantly different in leaf length and leaf width.
