Induction of systemic resistance in cucumber against shoot fungi by some biological resistance fungi

Abstract
The aim of this study was to find biological factors that increase plant growth and thus the resistance of shoot fungi without use chemical pesticides. In addition, the greenhouse study included isolation of a large group of soil fungi which located surrounding the roots system of cucumber. The results showed the ability of isolated fungi to dissolve the phosphorus in medium of NBRIP under shaking incubated conditions. The treatment of A. niger reduced pH function after 5, 10, 15 days of incubation of 3.760, 3.763, 2.947 respectively. The laboratory isolated fungi have also shown their ability to produce IAA. The results showed an increase in growth parameter of plants treated with A. niger and T. koningi2 by increasing the wet and dry weight of both shoots and roots. The evaluation results of peroxide enzyme production showed an increase of this enzyme when the plants have been treated with A. niger by 0.02067 compared to the control by 0.01333. This results indicated that the bio-resistance systemic has been induced in cucumber. Moreover, the pathogenic fungi did not recorded on the cucumber plant treated with bio-resistance systemic fungi. Whereas, the A. alternate fungi have been observed in the control treatment.
