| Abstract:
The life cycle of Pileolaria terebinthi was investigated under natural and greenhouse conditions. The fungus produced spermogonia, uredinoid aecia, uredia and telia on Pistacia mutica under both conditions. The life cycle of the rust fungus was completed in the greenhouse by inoculation of P. mutica with basidiospores. There was a significant increase in germination and germ tube growth rate in the dark for both types of spores. The teliospores germinated well in the range of 15-30oC but the differentiation of basidia occurred at 20-25oC. The optimum temperature for teliospore germination and basidium differentiation was 20oC. P. khinjuk was found to be a highly susceptible host of the fungus in the greenhouse inoculation experiments. Wild and cultivated P. vera cultivars were found to be susceptible to the pathogen. | |
