Arbuscular mycorrhizal fungus(AMF)is an important microorganism in ecological and agricultural systems,and it is well known that AMF inoculation can improve nutrient status of host plants.Recent researches show that the inoculation can improve quality of vegetable lants,but its role can be affected by the types of symbiosis,chemistry and physics aracter of soil and agricultural practice.Its mechanism relies on AMF inoculation to rove host plant nutrient status,to change carbon flux of the host plant,to influence host plant enzyme metabolize,to change plant hormone metabolism and the extrinsic nature of AMF.

The composition and content of glucosinolates(GSs)among 43 genotypes of Chinese kale(B.alboglabra Bailey)were analyzed,including five aliphatic GSs(2-hydroxybut-3-enyl GS,2-propenyl GS,4-methylsulfinylbutyl GS,4-pentenyl GS and 3-butenyl GS)and four indolyl GSs(4-hydroxyindol-3-ylmethyl GS,indol-3-ylmethyl GS,4-methoxyindol-3-ylmethyl GS and neoindol-3-ylmethyl GS).The main individual GS was 3-butenyl GS.The contents of total GSs,total aliphatic GSs and total indolyl GSs ranged from 3.369 5-21.337 8 mg•g^-1（DW）,1.539 7-17.264 5 mg•g^-1（DW）,0.797 6-9.590 0 mg•g^-1（DW）.
