Abstract
Responses of mycorrhizal and nonmycorrhizal bell peppers (Capsicum annuum) to solution phosphorus (P) concentrations ranging from 0.01 to 1.0 mg/liter were examined in a pot study. Mycorrhizal plants were inoculated at seeding with the vesicular‐arbuscular mycorrhizal fungus (VAMF) Glomus aggregatum (Schenck and Smith emend Koske). The peppers were transplanted Into a fumigated mix of Waialua clay soil (Vertic Haplustoll) and basaltic sand. At solution P concentrations between 0.01 and 0.03 mg/liter, inoculation with the VAMF increased P uptake, total dry matter production and fruit yields, while reducing the time to anthesis. At solution P concentrations above 0.4 mg/liter, mycorrhizal and nonmycorrhizal plants had similar growth and yields. Transplants with higher levels of root infection at transplanting produced greater final dry weights and fruit yields when planted into P‐deficient soil than transplants with lower levels of root infection, even though the highly infected transplants were F‐stressed and smaller than transplants with lower levels of infection. Extensive pretransplanting infection improved subsequent growth by reducing the time required for establishment of a functional mycorrhizal symbiosis following transplanting.
