Abstract

Fasciation in Casuarina equisetifolia.

Abstract

Fasciation (a malformation resulting in an enlarged and flattened stem) was observed in several provenances of C. equisetifolia during trials in Andhra Pradesh in 1996. The stems which developed were short, thick and 20-25 cm tall. The fasciated growth was 10-15 cm long, not extending beyond 20 cm [height], and the stems had nodes, internodes and needles, and were of a normal green colour. The malformation has been shown to be caused by Corynebacterium fascians in several other (flower) species, but treatment with oxytetracycline in 1997 made no difference to the symptoms observed.
