The effect of season on VA mycorrhizae of leucaena and mango in a semi‐arid tropic

Abstract

The effect of annual seasons on mycorrhizal colonization and sporulation by native mycorrhizal fungi was studied in two perennial tree hosts, viz., mango and leucaena. The results showed that maximum colonization and sporulation occurred during the winter (November to January) months. Summer months (April to June) were unfavourable for the proliferation of VA mycorrhizal fungi. There was a positive correlation between relative humidity and mycorrhizal activity, while the correlation between temperature (ambient and soil) and mycorrhizal activity was negative.

Key words:

• Leucaena
• mango
• season
• VA mycorrhiza
• sporulation
