Abstract and Figures The plant genus Swietenia of which S. macrophylla (Family: Meliaceae) belongs to, is used as herbal medicine for long time ago in … The plant, genus Swietenia of S. macrophylla (Family: Meliaceae) locally known in Malaysia as “Sky fruit”. Economically important timber tree, it is native to a number of North and South American countries including the USA, Mexico, Bolivia and central Brazil [3]. The hybrid occurs spontaneously in areas where the two parent species were planted in proximity; this hybrid has been reported in Taiwan and Indonesia. The research was conducted in March to July 2019 in the Botanical Laboratory, Faculty of Mathematics and Science of Natural Sciences, Universitas Negeri Padang. The influence of environmental pollution in plants can be seen from stomata in the leaves. The bole is straight, cylindrical, buttressed, and can be up to 120 cm in diameter. The Indian Council of Agricultural Research (ICAR) is an autonomous organisation under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture, Government of India. Due to the past indiscriminate felling, the mahogany of this species is not any more commercialized, it is available only rarely and in limited quantities, mostly coming from small African plantations; presently, the mahogany utilized comes almost exclusively from the Swietenia macrophylla, native to continental America, from Mexico to Bolivia and Brazil. S. macrophylla leaf color is generally red and then changed over time into green [8]. The product yields were collected at an interval of 25 °C. S. macrophylla is commonly grown in Singapore as an ornamental roadside tree and is one of the world's most valuable source of hardwood timber used to make furniture. Swietenia mahagoni is indigenous to Caribbean and southern Florida. ID - 81717. Longitudinal section of a seed revealed that the seed consists of a minute embryo embedded peripherally at one side within the massive cotyledons which is surrounded by a white thin testa which is again covered by dark brown coloured spongy tail-like wing. The variation in seed weight, germination percentage and germination period could be due to provenance differences, size of capsules, crown size of parent trees, level of seed maturity, site fertility, health condition of parent trees and environmental factors of a locality. in the research plot showed different leaf colors, 18 dark green, 12 green, and one yellowish green, respectively.
