Abstract:
Germination test and pot experiment have been used to study the effect of phthalate esters(DBP,DEHP )on 15 crops. The result,show that both DBP and DEHp(10mg/1 )has no significant effect on crop germination,but the mor-phological characters of crop seed ling have been changed to certain extent.Electron micrograph observations to su ffered Ieaves reveal that chloroplast structure is changed.The rela-tionship between esters(chemical and phyxical nature)and sensitivity of crons has been discussed too. The sensitivity or-der of vegetables to phthalate esters has been proposed through the study.
