Compost and biochar alter mycorrhization, tomato root exudation, and development of Fusarium oxysporum f. sp. lycopersici
Soil amendments like compost and biochar are known to affect soil properties, plant growth as well as soil borne plant pathogens. Complex interactions based on microbial activity and abiotic characteristics are supposed to be responsible for suppressive properties of certain substrates, however, the specific mechanisms of action are still widely unknown. In the present study, the main focus was...
متن کاملInteraction between Meloidogyne incognita and Agrobacterium tumefaciens or Fusarium oxysporum f. sp. lycopersici on Tomato.
Agrobacterium tumefaciens stimulated and Fusarium oxysporum f. sp. lycopersici inhibited development and reproduction of Meloidogyne incognita when applied to the opposite split root of tomato, Lycopersicon esculentum cv. Tropic, plants. The lowest rate of nematode reproduction occurred after 2,000 juveniles were applied and the fungus was present in the opposite split root. The effects of all ...
متن کاملInduced resistance in tomato plants by IAA against Fusarium oxysporum lycopersici.
The phytohormone IAA (indol-3-acetic acid) was tested in vitro on growth of tomato wilt pathogen Fusarium oxysporum lycopersici. The hormone reduced spore germination, mycelial dry weight and protein content. Such reduction was matched with the elevation in the hormone concentration. The in vivo application of IAA to soil of the uninoculated plants (controls) improved growth and yielded longer ...
متن کاملDeveloping of Dna-marker to the Fusarium Oxysporum F. Sp. Lycopersici Resistance Genes of Tomato
Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici is a destructive disease of tomato crops worldwide. The use of resistant varieties is the best strategy for disease control. In the present study we analyze eight tomato lines and hybrids for Fusarium wilt disease resistance by polymerase chain reaction. Total genomic DNA was extracted from young leaves of three-week-old plants of to...
متن کاملEvaluation of Plant Extracts against Fusarium Oxysporum F. Sp. Lycopersici, Wilt Pathogen of Tomato
Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...
