Intra-specific variation in pea responses to ammonium nutrition leads to different degrees of tolerance

▶ We studied adaptative responses to NH 4 + nutrition at the intra-specific level (4 pea varieties). ▶ Snap-pea variety is a reference for NH 4 + tolerance as its growth rate was not affected by N source. ▶ Snap-pea avoids the effects of NH 4 + through low growth potential, and high respiratory and...
