Abstract
Abstract. Although there are many different species of pepper plants (Capsicum spp.), all are from the New World tropics, and landraces such as Jalapeno (Capsicum annuum cv. Jalapeno) have been selected for optimum performance in response to local abiotic and biotic stresses. Pepper plants produce the phenolic compound capsaicin, primarily in the placenta of fruits, possibly to deter mammalian herbivores in favor of avian frugivores. Capsaicin content is influenced by genetic and environmental conditions including soil moisture and fertility, temperature, and light. In order to explore the relationship between abiotic stress and fruit capsaicin content, Jalapeno pepper plants were grown from seed, and then treated with 0.0, 0.5, 1.0, and 1.5% NaCl solution. Capsaicin extracts from Jalapeno fruits were analyzed using High Performance Liquid Chromatography (HPLC). None of the parameters tested were significantly different between the control or treatment groups, but the following trends were found in the da...
