Table In bulb of AMF inoculated
In bulb of AMF inoculated onion plant, micronutrients viz., zinc, manganese, copper and iron show substantial increases after initial days of growth. Later stages of growth add significant quantities of all these micronutrients in AMF presence, meanwhile maintaining a constant percentage increase at all stages of age with respect to those without AMF presence (Table 5).
HPLC analysis showed that various CD 2665 fractions present in onion bulb were being affected by AMF. The bulbs showed nearly 10 percent increase in starch content in inoculated plants than control. On the other hand, sugars like kestose, nystose, 1-fructofuranosylnystose and sucrose show prominent increase, wherein, the sucrose presence was nearly 80 percent higher in AMF presence. Glucose and fructose showed relatively low percentage and significantly decreased by mycorrhizal inoculation. Nystose presence in AMF inoculated plants was also nearly 15 percent higher due to AMF presence (Table 6). On GC–MS analysis, there were clear differences between the AMF inoculated and non-inoculated onion plants as far as phytochemical composition of onion bulbs is bronchitis concerned. Besides many differences in chemical composition, the two compounds in AMF inoculated plants stigmasterol and amyrins were of interest (Table 7).
