Abstract

In Algeria, chickpea (Cicer arietinum L.) is the second food legume produced after beans. Its cultivation has undergone a certain gradual evolution in terms of areas and consumption, and a regressive evolution in terms of productivity. Despite this importance, Chickpea is faced with many phytosanitary problems, the most damaging of which are caused by fungi. One of the factors that restricts the growth of Chickpea is fungal diseases which are the main biotic stresses. In the present study, the effect of different concentrations of Cytokinin and Fungal metabolic from Aspergillus fumigatus on the germination of two types of Chickpea (FLIP 85-55 and ILC 32-79) was investigated. At first, various pretreatments were done on the seeds, and after that, the seeds were sown in Petri dishes. The findings demonstrated that when the concentration of toxin (fungal metabolic) increased, the germination rate decreased. The type ILC 32-79 was less tolerant than the type FLIP 85-55. Contrarily, a prominent improvement in the rate of germination was caused by the cytokinin.
