| Summary: | The vesicular-arbuscular mycorrhizal (VAM) status of three vegetable crops viz., tomato, brinjal and chilli was
assessed during the initial establishment period in natural field conditions as well as in pot culture using nonsterile
soil. The soil had low nutrient status and no manurial application was made during the 60 d course of
the study. VAM fungal colonization in the roots was maximum at 45, 50, and 60 d after the respective germination
of brinjals, tomato and chilli seeds under field conditions, and on the 60th d in the pot culture experiment.
In no case was 100 per cent root colonization obtained. Ascending and descending trends in colonization were
observed. In all cases, the original spore count of3.90 (±0.30) g dry soil increased markedly in the rhizosphere soil
after plant growth. Spore number was more pronounced in pot than in field culture. |
