Effect of Indoleacetic acid (IAA) on the Negative Phototropism of Rice Root

Abstract

Abstract:

To explore the effects of IAA on negative phototropism of rice （Oryza sativa L.） root，agar block containing IAA was unilaterally applied on root tip to examine the phototropic response of root to exogenous IAA, and microstructure of the bending part was observed with an optical microscope. The growth of seminal roots could be regulated by exogenous IAA as well as light, as a result the root bent towards the site treated, causing asymmetric growth of the root cells at the elongation zone and consequently bending growth. IAA concentration in the shaded side of adventitious root increased much greater at 1.5 h after the start of irradiation. The unequal lateral IAA distribution can be concluded to be the main cause for negative phototropism of rice root.

Key words: rice, root tip, negative phototropism, indoleacetic acid
