Trichoderma citrinoviride suşları Fusarium oxysporium’e karşı T. Tüm suşlar litik enzim, indol asetik asit üretimi ve fosfat çözündürme özellikleri sergilemişlerdir. lerinin indol asetik asit üretimi ve fosfat çözünürleştirme kapasiteleri misel büyümesi ve konidium üretimi üzerine farklı karbon:azot kaynaklarının ve bazı fiziksel parametrelerin etkisi ile birlikte değerlendirilmiştir.

Farklı fitopatojenik mantarlara karşı mikoparazitik aktiviteleri ve ekstraselüler litik enzimleri üretme potansiyelleri incelenmiştir. moleküler metotlar kullanılarak tanılanmıştır. citrinoviride) türünün Trichoderma-tabanlı biyolojik kontrol ajanı potansiyelleri ve biyogübre özellikleri değerlendirilmiştir. 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. The effect of organic nitrogen sources on growth were notably higher than inorganic nitrogen sources. Both strains grew well on all carbon sources tested. atroviride strains were significantly higher than T. In particular, at lower temperatures, conidium production of T. atroviride was found more effective against Rhizoctonia solani. Trichoderma citrinoviride demostrated more mycoparasitic activity against Fusarium oxysporium than T. Results and DiscussionĪll strains exhibited lytic enzymes and indole-3 acetic acid production as well as phosphate solubility characteristics. were evaluated together with the effect of some physical parameters and different carbon:nitrogen sources on mycelial growth and conidium production. Furthermore, indole-3-acetic acid production and phosphate solubilization capabilities of Trichoderma spp. The mycoparasitic activities against different phytopathogenic fungi and their capacity to produce extracellular lytic enzymes were investigated. Materials and MethodsĮight Trichoderma spp. citrinoviride) were evaluated for their potential to have Trichoderma-based biological control agent and biofertilizer properties. Use of dinitrosalicylic acid reagent for determination of reducing sugar. Combinations of biocontrol agents for management of plant-parasitic nematodes and soilborne plant pathogenic fungi.

Lytic enzymes of Trichoderma and their role in plant defense from fungal diseases, a review. Isolates showing high levels of chitinase and $$-1,3-glucanase from the mycoparasitic fungus Trichoderma asperellum. asperellum isolates towards FOL and their lytic enzyme production. There was a correlation between the antagonistic capacity of T. asperellum isolates significantly reduced the mycelial growth of FOL isolates but the amount of growth reduction varied significantly as well. The random amplified polymorphic DNA (RAPD) method was applied to assess the genetic variability among the T.

The production of extracellular cell wall degrading enzymes of the antagonistic isolates was also measured. asperellum against 4 different isolates of FOL. We evaluated the antagonistic activity of 30 isolates of T. lycopersici (FOL) is a promising alternative strategy to pesticides for tomato wilt management. The use of novel isolates of Trichoderma with efficient antagonistic capacity against Fusarium oxysporum f.
