Ra. Gbadegesin, EFFECT ON THE DEVELOPMENT OF PINUS-CARIBAEA SEEDLINGS OF CERTAIN PLANT-PARASITIC NEMATODES FROM THE SAVANNA AREA OF NIGERIA, Forest ecology and management, 60(1-2), 1993, pp. 163-166
Seedlings of Pinus caribaea, grown in 24 cm mouth diameter pots, were
inoculated separately with each of six nematode genera and left to gro
w for 6 months in the greenhouse. Fewer Hemicriconemoides spp. and Tyl
enchus spp. were observed 6 months after inoculation. Inoculation of s
eedlings with Scutellonema led to increased root growth. Root and top
weights of seedlings grown in the soil infested with Criconemella spp.
were not significantly reduced. High inoculum density of Xiphinema an
d Rolylenchus caused a significant reduction of root and top weights o
f seedlings.
