- 摘要:
- 为研究大豆根系分泌物在大豆连作障碍中的作用,以二氯甲烷作为溶剂,提取培养28 d的大豆,小麦,玉米,高粱的根系分泌物,运用气质连用仪分离鉴定,找出大豆与其它3种作物根系分泌物的差异。结果表明:用该法鉴定出大豆根系分泌物成分77种,小麦97种,玉米84种,高粱80种。4种作物均鉴定出烷烃、醇、酸、酯、苯、酚、萘、酰胺、酮、醛类以及其他类化合物。将4种作物的根系分泌物进行比较,相同成分有丙三醇、2,4-戊二醇、邻苯二甲酸、乙苯、对二甲苯、苯乙烯、4-甲基-2,6-二叔丁基苯酚、甲基酚和一部分烷烃等。二苯呋喃,芴,3-甲基-4-氧-戊酸,2-亚甲基-丁醛,3-羟基-丁醛,己醛,9,10-二氢-11,12-乙酰-9,10-桥亚乙基蒽等是大豆根系分泌物中独有成分,其在大豆生长过程中的化感作用有待进一步研究。
- 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.
