| Abstract: |
| The uptake and distribution of MBC and Furadan in cotton seedli- ngs after seed-treatment with isotopic-and OSI-Technique were studied. Results show that the radioactivity in cotton seedling is in direct pro- portion to the radioactivity of the solution-treated cotton-seeds.Furadan is easier to penetrate through the cotton-coat than MBC.The radioa- ctivity in cotton seedling concentrated mostly on the first and second leaves.The cotton seedlings were found to obtain the radioactive che- micals through two w... |
