Identification of Cicer arietinum root exudation and allelopathy of benzaldhyde.
Abstract
Root exudates of Cicer arietinum seedlings were extracted and identified by gas chromatography-mass spectrometry (GC-MS) by CH2CI2, 35 days after hydro-culturing. Effects of the exudate benzaldhyde on germination were investigated. The components of the exudation mainly include organic acids, phenols, hydrocarbons, ketones, amides, benzene, aldehydes and thiazoles. Benzaldhyde had a stronger allelopathic effect on other crops than on Cicer arietinum itself, and the negative effect of benzaldhyde on multiple systems composed of two kinds of seedlings was less than for single crops.
