| Abstract: | Mycorrhizae are fungal symbionts forming mutualistic relationships with plant roots. This study was undertaken to evaluate the overall influence of arbuscular mycorrhizal fungi (AMF) on the overall growth and development of carrot plant. Surface-sterilized seeds of carrot were sown in earthen pots filled with sterile soil. Half of the pots were inoculated with AMF spores; the other half without any AMF inoculation represented control. After germination inoculated plants, along with the controls, were sampled at 20, 40, 60 and 80 days of growth after seedling emergence. There is a progressive net increase in growth with each 20-day interval after seedling emergence. Storage roots of carrot had a higher level of metabolites and nutrients like nitrogen, phosphorus and potassium in mycorrhiza colonized plants than the control. High performance liquid chromatography analysis indicated an increase in the carbohydrate fractions in AMF-inoculated roots. Thus, mycorrhiza has been found increasing the growth, metabolites and nutrition of carrot plant. |
