Abstract

Evaluation of the structure of the caryopsis transfer system is presented for an Avena magna × A. longiglumis amphiploid. Each component of the system such as vascular bundle, pigment strand, nucellar projection and ventral aleurone layer varies between the amphiploid and its parental species. The number of xylem vessels present in the caryopsis bundle expressed heterosis-like inheritance. The position of the caryopsis xylem bundle in A. longiglumis shows a lower efficiency in assimilate transport. Some anomalies in the development of the ventral aleurone layer and parenchyma, adjacent to the transfer system, are presented.

Caryopsis xylem bundles in parental species Avena magna (A) and A. longiglumis (C), and in the amphiploid (B). Caryopsis transfer system in A. longiglumis (D) and in the amphiploid (E). np – nucellar projection; ps – pigment strand. Xylem bundles are encircled by green dotted lines. Thick cell walls isolating the vascular bundle are indicated by white arrows in E. Absence of aleurone layer at the border between the nucellar projection and starchy endosperm is indicated by a green arrow in D. A-C – as observed under polarising light; D, E – epifluorescence images. Microscope magnification for A-C – ×200; for D, E – ×80.
