Title: Changes in the Root System of Wheat Seedlings Following Root Anaerobiosis II. Morphology and Anatomy of Evolution Forms
Abstract: Morphological and anatomical parameters which are variable under root anaerobiosis in Triticum aestivum were checked on five taxa of primitive and modern wheats (and the related genus Aegilops). The plants were grown in nutrient solution which was either aerated or flushed with nitrogen. When the plants were flushed with nitrogen a general retardation in longitudinal root growth occurred in all of them, but only Triticum aestivum showed a clear promotion of growth of later appearing roots enabling it to maintain the same root/shoot ratio even under stress conditions. There was an increase in the volume of intercellular space in the root cortex of nearly all the plants investigated. The diameter and the lignin content of the roots and the form of their cortical cells also varied. All these changes were expressed in the primitive wheats to a lesser extent than in the advanced Triticum aestivum indicating that there is a clear increase in the adaptive response in the latter.
