Abstract

Anatomical response of rice (Oryza sativa L.) to aluminium toxicity grown in sand culture and half strength Hoagland solution revealed that aluminium stress caused a decrease in diameter of the root and the shoot. Aluminium toxicity reduced the number of metaxylem vessels in the root of rice. Number of sclerenchyma cells was more in aluminium-treated rice root. Under Al stress, smaller sized vascular bundles were found in the leaf of rice. Size and frequency of bulliform cells were increased in the leaf of Al-treated plants than that in control plants. Al treatment caused closure of stomata in rice leaves.
