| Abstract: |
| Recently， the…soil…heavy…metal…pollution…is…increasingly…serious， the…normal…growth…and…physiological…
ecology…characteristics…of…plants…are…affected， and…then…threats…the…safety…of…agricultural…products.…Organic…acids…can…
repair…the…pollution…soil， make…the…ion…metal…state…transformed…into…the…low-toxic…or…non-toxic…state…through…chelating…
metal…elements， for…increasing…the…resistance…of…plants…to…heavy…metal…stress.…So…organic…acids…are…often…thought…to…play…
an…important…role…in…plant…resistance…to…heavy…metals.…This…paper…introduced…the…change…of…content…and…element…of…organic…
acids， including…oxalic…acid， malic…acid， citric…acid， tartaric…acid， succinic…acid， lactic…acid…and…acetic…acid…and…so…on，
and…clarified…the…mechanism…how…to…increase…the…resistance…to…heavy…metal…stress…in…plants…and…roots…secretion…grown…in…
soil…with…cadmium， lead， aluminum， zinc…and…copper…pollutions， at…last， put…forward…the…research…direction…of…organic…
acid…detoxification…in…plants…under…heavy…metal…stress. |
