Comparación de dos técnicas de cuantificación de infección micorrítica

摘要: COMPARISON OF TWO TECHNIQUES FOR DETERMINING MYCORRHIZAL INFECTION Our aims were to compare the techniques for determining root mycorrhizal infection proposed by Giovanetti-Mosse and Trouvelot et al. Data extracted from a glasshouse experiment where wheat plants grown in pots filled with Petrocalcic Paleudoll soil. Treatments nitrogen phosphorus fertilization levels three sampling depths. Mycorrhization (M) estimated both methods ranged 0 about 68 %. Arbuscules (A) 61 There found positive (up r2= 0,77) relationships between M A. Similarly, there 0,76) when or A two correlated. method showed M% values lightly highest (MTrouvelot(%)= 0,98 MGiovanetti (%) – 4,1; 0,81). similar trend (ATrouvelot(%)= 0,82 AGiovanetti 4,2 r 2= 0,76).
