Note on the occurrence of nodules in the New Zealand species ofCoriaria

Abstract

The root systems of all recognised New Zealand species of Corjaria and several of the hybrids were found to be nodulated. Ecological notes on the sites where plants were investigated and some comments on the significance of the genus in the New Zealand vegetation are included.

Plant-endophyte symbiosis in non-leguminous plants

“…These Coriaria species are vigorous colonizers of sand and gravels. Especially the hybrids are exceedingly aggressive and quickly occupy broken ground or disturbed areas (Oliver, 1942;Burke, 1963). According to the present author the introduction of some of these New-Zealand Coriaria species as soll conditioners in other countries will be of economic significance.…”

“…Further, Morrison and Harris (1959) mentioned that C. sarmentosa bore no nodules in its natural habitat of Otago, New Zealand. But later Burke (1963) surveyed the root systems of all New Zealand species of Coriaria and found C. sarmentosa was also nodulated and that nodulation occurred in all eight Coriaria species and their hybrids. These Coriaria species are vigorous colonizers of sand and gravels.…”
