Identification of allelochemicals under continuous cropping of Morchella mushrooms.

ABSTRACT: Continuous cropping obstacle has been becoming the bottleneck for the stable development of morel cultivation. The allelopathic effect of soil allelochemicals may play an instrumental role in the morel soil sickness. In this study, the allelochemicals were identified by gas chromatography-mass spectrometry (GC-MS) combined with in vitro bioassay. A total of 61 chemical substances were identified through the GC-MS analysis of 12 replanting and control soil samples, comprising 10 phenolic acids, 36 acids, 3 aldehydes, etc. Among which, 15 compounds with values of variable importance for the projection (VIP) greater than 1 in the orthogonal partial least squares-discriminant analysis (OPLS-DA) were selected as the differential metabolites between soil samples of continuous cropping and contro
