Abstract:
Factorial experiment was conducted in pots to study the effects of the inoculation of Mycorrhiza fungus
G. mosseae,Trichoderma fungus T. harzianum,Rhizoctonia fungus R. solani and their interaction on the
perecentage of Mycorrhiza infection root, shoot part dry weight,phosphorus concentration in the green part and
disease severity of R. solani. The results revelled that infection of R. solani gave 75% the cabbage, antibiosis of
isolate T. harzianum was 2 to put Bell.The results showed the inoculated treatments of G. mosseae and
T. harzianum were significantly increased comppared with non inoculated treatments of Mycorrhiza infection
perecentage of root, shoot part dry weight,phosphorus concentration in the green part, The perecentage
inceeased with G. mosseae and T. harzianum inoculated were((200,46,50), (30,42,36)%for three characters
respectively.
As for the inoculated treatments of R. solani was negative and cause adecrease in the Mycorrhiza infection
perecentage of root, shoot part dry weight and phosphorus concentration in the green part compared with non
inoculated treatments of R. solani,
its give without inoculated treatments of R. solani(48.75%,21.22g gm.plants-1,0.28%)while inoculated treatments
of R. solani(26.25%,15.7822gm.plants-1,0.17%) for three characters respectively.
The interaction between G. mosseae and T. harzianum significante increased on the dual inoculated compard with
alone treatments in shoot part dry weight,of value combined inoculation of G. mosseae and T. harzianum
(25.72gm.plants-1)while inoculated treatment of M+T-( 18.3272gm.plants-1)and inoculated treatmentM- T+
(17.813272gm.plants-1). The influence interaction combined of M+T+R- showed maximum concenteration in
Mycorrhiza infection perecentage of root, shoot dry weight and phosphorus concentration in the green part were
give(75%,27.52 gm.plants-1,0.37%), and non infection disease severity of R. solani was give 0. Morever, adding
M-T-R+minimum concentration were (10%,9.08 gm.plants-1,0.13%) and maximum of disease severity was
in shoot dry weight,phosphorus concentration in the green part 0.75. too superior treatmens M-T+R+ on M+T-R+
13.90 ()but M+T-R+ %,0.3 gm.plants1 -,0.18 and disease severity of R. solani, were gave M-T+R+(16.22
%) for three characters respectively. ,0.16, 0.43 gm.plant |
