STRUCTURAL STUDIES ON ROOT-NODULES OF LEUCAENA-LEUCOCEPHALA WITH
PARTICULAR REFERENCE TO THE INFECTION PROCESS
IQBAL R; MAHMOOD A
Abstract: Rhizobial infection on roots of Leucaena leucocephala started with
curling and deformation of root hairs. Infection threads were seen in
the young infected cells travelling both inter and intracellularly.
Bacteroid region of the nodule composed of both the infected
parenchymatous cells and uninfected interestitial cells. Two types of
infected cells viz., young vacuolated cell and older non vacuolated
cells with deformed nuclei were observed in the developing nodules. Both
determinate and indeterminate nodules were observed in L. leucocephala.
