Phytotoxicity of culture filtrate of Aspergillus terreus on paddy seed germination and seedling growth

Saini Kiran1, Maganti Surekha2, Solipuram M. Reddy2

The effect of 7 days old culture filtrate of mycotoxigenic Aspergillus terreus was tested on paddy seed germination and seedling growth was studied. The culture filtrates of A. terreus were toxic to seed germination of all the three varieties of paddy. However, the toxicity varied significantly with the age of culture filtrate and the variety of paddy seed.
The Variety comparatively more resistant to A. terreus, while vijayamashuri variety was highly susceptible. The Phytotoxicity could be attributed to territrem B.
