Ascospore Concentration Over Onion Field

Abstract

The investigation of air borne fungi was carried out by using continuous Tilak air sampler over Onion (Allium cepa L. Family- Liliaceae) field during rabbi season 1^st November 2014 to 27th January 2015. In this investigation the maximum concentration of ascospores 22.09%/m³ of air were recorded in the month of December and minimum in the month of November  13.18%/m³ of air.It becomes very clear that there is a close relation between cold and humid environmental condition and release of ascospore.
