Journal ArticleDOI
A survey of angiosperm species to detect hypodermal Casparian bands. II. Roots with a multiseriate hypodermis or epidermis
TL;DR: Hypodermal Casparian bands were found in roots of hydrophytic, mesophytic and xerophytic species and in members of primitive as well as advanced families, suggesting that this feature has been retained by many species in this group.
Journal ArticleDOI
Deposition of Casparian bands and suberin lamellae in the exodermis and endodermis of young corn and onion roots
TL;DR: Both the exodermal Casparian band and suberin lamella matured closer to the tip in onion than in corn roots, and the growth rate of corn roots was drastically inhibited by adding polyethylene glycol to the h...
Journal ArticleDOI
Development of the Hypodermal Casparian Band in Corn and Onion Roots
TL;DR: Using the apoplastic fluorescent dye, CFW, a permeability barrier could be distinguished in the radial walls of the hypodermis 40-50 mm from the root tip in corn and onion and uranin at a concentration of 0-01% proved nontoxic to Corn and onion roots on the basis of root growth tests.
Journal ArticleDOI
A survey of angiosperm species to detect hypodermal Casparian bands. III. Rhizomes.
TL;DR: It is concluded that Casparian bands are present in the hypodermis of rhizomes of all species surveyed and are resistant to treatment with concentrated sulphuric acid.
