Somatic association of chromosomes and other mitotic abnormalities in Vanilla planifolia (Andrews)

Abstract

Abnormal mitotic behaviour in Vanilla planifolia is analysed with special emphasis to association of somatic chromosomes. Indications of somatic association were evident in interphase, prophase and metaphase stages of root tip mitosis. Reasons for somatic association is discussed. Possible origin of vanilla as a hybrid is suggested. Role of somatic association in enriching variability is also discussed. © 1994 Taylor & Francis Group, LLC.
