Abstract: | Zilla spinosa plant part extracts exhibited significantly different inhibitory effect on the seed germination and seedling
growth of its associate species. Shoot extract reduced the percentage germination and seedling length of different test species
more than root extract. Except of Z. coccineum, seedling growth was more sensitive than seed germination. Shoot/root ratio
of all test species increased significantly with increase in extract concentration. Mycelia growth of the two rhizosphere
fungal species was more significantly reduced by Z. spinosa shoot extract than root extract. The effects of the different
extracts on total protein and total carbohydrate contents of the two test species were comparable. Non-significant increase
was recorded at low concentration of both shoot and root extract. However, with the rise of extract concentration, highly
significant reduction in the content of these metabolites was recorded.
