“…Sangeetha (2003) in her studies with C. gloeosporioides isolated from mango, observed heavy sporulation of the fungus when maltose was used as a sole carbon source. According to Chaturvedi (1965), glucose, fructose, maltose and starch supported good sporulation of C. gloeosporioides, the incitant of leaf spot of Polyscias balijuriana. Similarly, Saxena (2002) reported that sucrose was a good sporulating compound for C. gloeosporioides isolated from pomegranate.…”

The paper gives an account of the variations in nutritional and physiological characteristics found in different isolates of Colletotrichum gloeosporioides causing anthracnose disease of papaya, in India. The pathogen under study varied in its ability to utilize different carbon and nitrogen sources. Fructose was found to be the best source of carbon for the growth and sporulation of most of the isolates. Among the nitrogen sources tested, aspartic acid supported the maximum growth of isolates followed by potassium nitrate and proline. In contrast to this, isolates sporulated better in media containing potassium nitrate, ammonium nitrate or sodium nitrate as the sole nitrogen source. The response of different isolates to different temperature levels were found to be vary. However, most of the isolates preferred temperature range of 28 0 C to 30 0 C for the growth and sporulation when grown on Richard's agar medium. C. gloeosporioides isolates grew well at pH 5 while sporulation was better at pH 6.
