The effect of the vesicular-arbuscular mycorrhizal fungus, Gigaspora margarita, on the growth and development of sweetgum (Liquidambar styraciflua) at two phosphorus levels in a loamy sand soil and in kaolin mine spoli is reported. Total biomass production, growth rate, foliar nutrient content and mycorrhizal development in 161-day-old seedlings are presented. Non-mycorrhizal seedlings grew best in a loamy sand soil supplemented with 100ugPg-1, but in kaolin spoil did not respond to this rate of fertilization unless they were mycorrhizal. In soil receiving 25ugPg-1, growth rate of mycorrhizal seedlings was significantly greater than that of non-mycorrhizal seedlings and foliar levels of P, Mg, and Ca were enhanced by both mycorrhizal colonization and P fertilization. Mycorrhizal development and spore production were supressed at the high P level. |
