| Popis: | The effect of temperatures and exogenous supply of different carbon and nitrogen sources on the conidial germination and appresoria formation inC. capsici has been studied. 25 °C was observed to be the best temperature for conidial germination. At 18 °C, conidia germinated only in hanging drops and did not germinate on 2 % agar. Amongst carbon sources, 1-rhamnose supported maximum conidial germination and appresoria formation. Potassium nitrate supported very good conidial germination and appresoria formation. Ammonium nitrate, ammonium sulphate and ammonium chloride were found to be inhibitory. A few aminoacids stimulated conidial germination but dl-alanine, dl-methionine, tyrosine and l-glutamine were found to be inhibitory. |
