Abstract

SUMMARY Four different light intensities exerted distinctly different effects on the formation, reproduction and influence of vesicular‐arbuscular mycorrhiza on onion plants. Over a growth period of 100 days, the rate of infection under low light intensities (5 and 10 klux) was more rapid and the percentage of infection higher than on mycorrhizal plants cultivated under a light of 15 and 20 klux. The production of spores increased with light intensity. A plant growth enhancement occurred at all light levels but was most pronounced under a 10 klux light regime.
