Summary: | Abstract
Background
Two
Trichoderma
species (
T. atroviride
and
T. citrinovirid
e) were evaluated for their potential to have
Trichoderma
-based biological control agent and biofertilizer properties.
Materials and Methods
Eight
Trichoderma
spp. were identified by molecular methods. The mycoparasitic activities against different phytopathogenic fungi and their capacity to produce extracellular lytic enzymes were investigated. Furthermore, indole-3-acetic acid production and phosphate solubilization capabilities of
Trichoderma
spp. were evaluated together with the effect of some physical parameters and different carbon:nitrogen sources on mycelial growth and conidium production.
Results and Discussion
All strains exhibited lytic enzymes and indole-3 acetic acid production as well as phosphate solubility characteristics.
Trichoderma citrinoviride
demostrated more mycoparasitic activity against
Fusarium oxysporium
than
T. atroviride
whereas
T. atroviride
was found more effective against
Rhizoctonia solani
. In particular, at lower temperatures, conidium production of
T. atroviride
strains were significantly higher than
T. citrinoviride
strains. Both strains grew well on all carbon sources tested. The effect of organic nitrogen sources on growth were notably higher than inorganic nitrogen sources.
Conclusion
The results provided valuable insight in both the highest mycelial growth and conidia production conditions of these cultures for further similar studies related to development of
Trichoderma
-based new commercial biological control and biofertilizer formulations in different agro-climatic regions. |
