Volatile allelopathy in velvet bean (Mucuna pruriens [correction of pruiens] L.) and gravity

Allelopathy caused by volatile compounds was studied with velvet bean (Mucuna pruriens [correction of prueiens] L.). Preparatory experiment was conducted to identify the relationship between action of volatiles and gravity. The experimental protocol was defined and tested to study on volatile allelopathy of velvet bean. Root growth of lettuce (Lactuca sativa L.) seedlings was inhibited by volatile gas from velvet bean seedlings planted in Agripot. In this study, it was shown that ten-day velvet bean seedling could exhibit the volatile allelopathic ability. Growth chambers for volatile experiment were designed. Velvet bean seed can germinate in a 3-ml small vial.
