Abstract
The effect of autoclaving soil on vesicular-arbuscular mycorrhizal (VAM) fungal colonization and biomass production of tomato (Lycopersicon esculentum Mill) was assessed in pot experiments under greenhouse conditions. Four treatments were given viz. (1) VAM-free plants in autoclaved soil (2) VAM plants in autoclaved soil (3) VAM plants in autoclaved soil amended with VAM-free filtrate of non-autoclaved soil and (4) VAM plants in non-autoclaved soil. The VAM plants grown in non-autoclaved soil showed the highest root colonization of 87.78 while those under (2) and (3) showed only 55.11 and 56.94 respectively. On the other hand significantly higher shoot length (105.4 cm/plant) total leaf area (740.3 cm 2 /plant) and biomass (8.43 g/plant) were obtained in VAM plants grown in autoclaved soil. VAM-free plants in autoclaved soil had reduced growth. In treatments 3 and 4 plant growth was intermediate. The results indicate that VAM colonization and sporulation were favoured under natural conditions but VAM plants under autoclaved soil conditions produced maximum growth.
