| Abstract: |
| To investigate the relation between root anatomical structure and tolerance to drought of maize,experiments of maize with different tolerance to drought were conducted in the field.The microstructure of primary root and different secondary roots were studied by hand sectioning and routine mineral wax moviemaking.The result showed that the maize with high tolerance to drought had fewer cortex cell layer numbers,lesser diameter of metaxylem vessel,more metaxylem vessel amount in primary radicel,and fewer cortex cell layer numbers,more metaxylem vessel and lesser diameter in various secondary roots, compared with the maize with low tolerance to drought. |
