Highlights:
The addition of deuterium-depleted water in the growth of maize seedlings causes the appearance of aeriferous cavities in internal structure of the root. The number of vascular bundles is higher compared to the control. In the adventitious root, the root hairs are more numerous compared to the control.

Abstract

The paper presents histo-anatomical aspects, evidenced in seedlings of maize (Zea mays L.) grown under the influence of deuterium depleted water (DDW). The aim of this study was to identify the internal structure changes in maize seedlings resulted in this case.

For histo-anatomical characterization, the vegetal material was fixed and preserved, following to be cut by hand microtome with botanical razor. The sections obtained were stained using double staining reagents.

As compared with the control sample it was obsereved that deuterium depleted water determines a better development of the absorbents bristle and increase leading bundles number and central vessels in metaxilem. Keywords: deuterium depleted water, maize, histo-anatomical investigations
