Abstract
The semiarid region of Brazil is marked by scarce rainfall and high temperatures. The Caatinga biome, established in this region, has great diversity of plants with economic potential and applications, such as in herbal medicine. Plant representatives include those of the family Lamiaceae, which has 240 genera and 7200 species. The essential oil of the species Medusantha martiusii, popularly known as “alfazemas de caboclo”, has often been found to have biological activities, such as cytotoxic, antimicrobial and insecticidal effects, thus making this species economically important. The objective of this study was to characterize the climatic, geographical and edaphic aspects of sites where M. martiussi naturally occurs in the state of Bahia in order to understand the possible relationships and interactions between the environment and plant growth, development and production of essential oils. Vector files with climate, geomorphology, phytophysiognomy, and soil data were examined and the data were systematized and analyzed. The species occurs in semiarid areas with nutrient-poor, acidic and well-drained soils. The species has broad range of thermal adaptation, occurring from mountainous regions with high relief to low altitudes and in climatic zones characterized by scant and poorly distributed rainfall. The essential oil content showed a quantitative variation across the surveyed sites, with an average of 2.07% by dry weight of leaves and flowers, and a moderate and significant interaction of the essential oil with Fe and Zn concentrations present in the soil were also observed.
期刊介绍:
Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation.
Areas of particular interest include:
-crop evolution
-domestication
-crop-weed relationships
-related wild species
-history of cultivated plants including palaeoethnobotany.
Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources.
Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany.
All contributions are in the English language and are subject to peer reviewing.
