The Pythium suppressive ability of Glomus intraradices in cherry tomato propagation
نویسندگان
چکیده
This experiment aims at establishing the ability of the endomycorrhizal fungus Glomus intraradices to suppress the plant pathogen Pythium ultimum in cherry tomato. A study published in Canadian Journal of Plant Pathology in 1994 showed that Glomus intraradices suppresses Pythium ultimum in Tagetes patula (french marigold) (St-Arnaud, Fortin, Caron, & Hamel, 1994). Pythium ultimum and other Pythium species are fungi-like organisms which cause Pythium damping-off, a serious disease of seeds and seedlings (Hartmann, Kester, Davies, & Geneve, 2011, p.217). Pythium species resemble parasitic brown algae and are not considered to be true fungi (Dreistadt, 2004, p.268). Pythium ultimum is one of the three most commonly encountered species of Pythium, the other two being P. aphanidermatum and P. irregulare (Moorman, 2014).

Damping-off diseases incited by different species of Pythium are a persistent problem worldwide, often resulting in reduced yields and occasionally resulting in major crop damage. There have been increasing restrictions on the use of chemical fungicides, and the development of disease-suppressive biocontrol agents has become a major goal of horticulture crops. An experiment was conducted with t...
متن کاملThe bacterium Paenibacillus validus stimulates growth of the arbuscular mycorrhizal fungus Glomus intraradices up to the formation of fertile spores.
Two isolates of Paenibacillus validus (DSM ID617 and ID618) stimulated growth of the arbuscular mycorrhizal fungus Glomus intraradices Sy167 up to the formation of fertile spores, which recolonize carrot roots. Thus, the fungus was capable of completing its life cycle in the absence of plant roots, but relied instead on the simultaneous growth of bacteria. The supernatant of a mixed batch cultu...

PHL-C is one of the dwarf sweet cherry rootstocks which is a hybrid between P. avium L. × P. cerasus L. Direct rooting of sweet cherry rootstocks is difficult which can be solved by using in vitro propagation. Transfer of plantlets from in vitro to ex vitro limit the use of micro propagation, because of weak root systems and low survival rates. This study was conducted in order to select the be...

Field experiments were conducted near Weslaco, Texas (Lat. 26° 8' N) between 1999 and 2001 to evaluate the field performance of preand post-mycorrhizal inoculations of tomato and onion (2001 only) transplants. In 1999 ‘Heatmaster’ tomato (Lycopersicon esculentum Mill.) transplants were inoculated with Glomes intraradices (Reforestation Technologies, Salinas, CA) at transplanting; in 2000 ‘Heatm...
