Summary
Expanded pools of ammonium and amino-N were found in fronds of Azolla plants experiencing P deficiency and crowding. A larger and more rapid increase in pool size of these compounds was found in P-deficient plants than in crowded populations. High temperature did not limit their accumulation in P-deficient fronds of all the strains examined exceptA. caroliniana.
