The enzymic activity of Macrophomina phaseoli, (Maubl.), Ashby

  • Published:
Proceedings / Indian Academy of Sciences

Summary

  1. 1.

    The pectin content of frenchbean plants infected withM. phaseoli was 50% less than that of correspondingly healthy plants.

  2. 2.

    That the loss of pectin in the diseased frenchbean plants was due to pectolytic enzyme activity of the pathogen was proved byin vitro studies on cut bits of potato with enzymic extracts of the fungus.
