The results show ed that aluminum remarkably restrained P . sativum root and bud from grow ing . The initial on entration of aluminum poisoning ell split of P . sativum root top w as 1mgL- 1 . As aluminum indu ing the various hanges have taken pla e in the hromosome of P . sativ um root top, aluminum initial on entration being 0. 5mgL- 1 . Between aluminum restraining P. sativ um root and bud from growing and this plant absorbing Ca and Mg there is not learly relation under its less on entration ( 15mgL- 1) . Key words Pisum sativum seed, aluminum, root, bud, ell. 1
