Glomus intraradices Attenuates the Negative Effect of Low Pi Supply on Photosynthesis and Growth of Papaya Maradol Plants

Figure 4

Chlorophyll fluorescence (F_V/F_M) found at week five of the experiment in papaya Maradol plants grown with or without mycorrhiza with (a) Pi 0 mM, (b) Pi 0.3 mM, and (c) 0.6 Pi mM. Control group was grown without AM fungi supplied, with Pi 1.0 mM. Data are means ± SD (𝑛=5). Values with the same letter for treatments within each week had no statistical difference (Tukey 95%).
