Luminosity, temperature, and substrates on the germination of Solanum capsicoides

Solanum capsicoides, commonly known as red soda apple, is a little-studied species with phytotherapeutic characteristics of interest to the pharmaceutical industry. However, little about its agronomic characteristics. Therefore, this study aimed assess effect light, different temperatures, and substrates on germination S. capsicoides seeds. The consisted two experiments: Experiment I - Germination seeds under wavelengths. were kept Petri dishes covered Germitest™ paper moistened distilled water exposed monochromatic, red, far-red, dark experiment was performed in completely randomized design four replications 25 II at temperatures. distributed according six substrates: roll, paper, between sand, soil + sand manure, manure. also subjected constant temperatures 20, 25, 30, 35 °C alternate 20-30, 20-35, 25-30, 25-35 °C, characterizing 6 x 8 factorial arrangement. rate, speed index, mean time evaluated. Red apple are classified positive photoblastic, highest rate occurring temperature 20-35 combined substrates.
