Fig. 8. — Dynamics of the main-shoot spike length from the onset of stem elongation to the beginning of grain growth for the durum wheat cultivars: Claudio, Donduro, Simeto, and Vitron (in experiment 1; A) or Donduro and Vitron (in experiment 2; B) under low (N50, open triangles) and high (N250, open circles) N availabilities; and irrigated or rainfed conditions (experiment 2; B). For each spike length, a bilinear model [Y=A+B×X×(X≤C)+B×C×(X>C)] was used where Y=spike length (cm) and X=thermal time from sowing (ºC d).
