Abstract:
In order to study the function of soybean root exudates in soybean continuous cropping obstacles，compounds extracted with dichloromethane from root exudates of soybean，wheat，corn and sorghum seedlings，were isolated and identified by GC-MS analysis，the different root exudates between soybean and the other three crops were searched.It showed that the composition in the root exudates of soybean，wheat，corn and sorghum were 77，97，84 and 80 species，respectively.Alkanes，alcohols，acids，esters，benzene，phenol，naphthalene，amides，ketones，aldehydes and other chemical compounds were identified in the four crops.The common ingredients were identified in the root exudates of the four crops，such as glycerol，2，4-pentanediol，phthalic acid，ethylbenzene，paraxylene，styrene，butylated hydroxytoluene，methyl alkanes，and a part of alkanes.The specific compounds of soybean root exudates were dibenzofuran，fluorene，3-methyl-4-oxo-pentanoic acid ，2-methylene-butanal，3-hydroxy-butanal，hexana and 9，10-dihydro-11，12-diacetyl-9，10-ethanoanthracene.
