| Description |
Pathogenic ability of many fungal species qualified for nine of genera were recognized. (8) fungi were optimistic and positively talented to contaminate leaves of tomato seeming contamination indicators for the disease ( leaf spot) . Alternaria citri Alternaria alternata , Alternaria tenuissima , Botrytis cinerea , Botrytis squamosa were extremely infectious and formed this desease in most of infested leaves . Consequences protest this , in unhealthy plant life by Alternaria citri the chlorophyll was tremendously communicable presented maximum ominously condensed in (1.16 - 0.18) (mg/g fresh leaves ) for chlorophyll( a, b) individually associated in (2 - 1.50) (mg/g fresh leaves ) in controller plants. Alternaria alternate also march exciting condensed for chlorophyll (a, b ) were ( 1. 89 - 0.98) (mg/g fresh leaves ) correspondingly. (6) species were divided to capabilities to products pectinase by (cup-plate) technique. Totally mycological verified remained (pectinase ) inventors then through adaptable shades. (3 )species displayed in height pectinase inactivity include(Alternaria citri, Alternaria tenuissima and Alternaria alternaria) were( 29, 26 and 23 mm) correspondingly, further species were create to be practical pectinase action include(Mycosphaerella tassiana, Botrytis squamosal , Botrytis cinerea). Pectinase formed by Alternaria citri increased by increasing of incubation dated exhibition its supreme afterwards (ten days ) of incubation, in (30°C , pH= 6). Among numerous carbon cradles shared definitely in the media , (pectin) shaped resolute pectinase structure through Alternaria citri, whereas (peptone )was greatest nitrogen foundation considerable measures to pectinase. https://doi.org/10.24897/acn.64.68.485
