Cultures of Azolla caroliniana Willd. These symbiontfree plants can be maintained only on medium containing a combined nitrogen source.

Plants of the Gila Wilderness

Morphological aspects of the symbiotic association show the confinement of the Anabaena azollae within the leaf cavity of the Azolla. Procedures were established for the isolation of pure preparations of Anabaena azollae and Azolla chloroplasts.

It has not yet been possible to grow the isolated alga in independent culture. Photochemical activities of the isolated alga and fern chloroplasts were measured by spectrophotometric assays for photosystems I and II as well as by Pcontent photosystem I and delayed light emission photosystem II.

In the algal fraction, both photosystems were repressed when compared to freeliving Anabaena cylindricabut the relative ratio of photosystem I to photosystem II may be appreciably greater in Anabaena azollae. Azolla chloroplasts were generally comparable to spinach chloroplasts.

A comparison of the chlorophyll a and b content of Azolla fronds with and without the symbiotic alga resulted in an estimate that in the symbiotic association, the Anabaena azollae accounts for from 7.
