摘要:

Two soybean varieties were grown at different P levels to test tolerance to high levels of P. When Hawkeye and PI54619–5–1 soybeans,Glycine max(L.) Merr. Bragg, were grown in solution culture with NH4H2PO4increasing from 10‐4Mto 3 × 10‐2M,yields of Hawkeye were decreased more by the highest P levels than were those of PI54619–5–1. The high P also resulted in larger concentrations of Zn, Cu, and other heavy metals in Hawkeye man in PI54619–5–1. Phosphorous concentrations were generally higher for Hawkeye than for the PI54619–5–1 soybeans. PI54619–5–1 leaves contained less of most metals than the Hawkeye.
