Evaluation of Pongamia pinnata Products against the Sclerotium rolfsii Extracted from Chickpea

Iram Shaheen, Sajida Parveen and Zahida Parveen

This study was conducted to investigate antifungal properties of Pongamia pinnata products. Pongamia pinnata seed oils and leaf diffusates contain products that show fungi-static effect against Scelotium rolfssi on Chickpea. This study shows comparison between antifungal effects of Pongame seed oils and Leaves, as both of these potentially inhibit Sclerotial production and germination of S. rolfsii. It was noticed that ingredients of leaves were changed when autoclaved. It also showed that there were some ingredients that were altered in terms of composition when heated. These agents were thought to be proteins and carbohydrates. Similarly, ingredients of seed oil also undergo change in composition when autoclaved. Extract showed insignificant difference about 20% (v/v) in inhibiting concentrations when used before autoclaving, while there was a significant difference among various concentrations after autoclaving. This significantly increased inhibition was present in Sclerotial production, germination and growth of mycelia. Overall, leaf extract was more effective than seed oil extract.
