SIZE DISTRIBUTION: 40-140 µm, mean = 93.3 µm (n = 170). Similar spores were also observed in ex-type pot cultures of A. delicata (W5747 of 14 Apr 2010 from INVAM AZ661, Att218-5, Fig. 1 C) and ex-epitype cultures of A. cavernata (W5738 of 20 Apr. 2010 from BEG33, Att209-66, Fig. 1 D).Total mycorrhizal root length = R2 + R3. Total plant root length can be estimated by substituting R1 for R2 in the same set of calculations. This estimate is valid only if the root architecture in the small sample (which usually consists of only fine roots) resembles that of the rest of the root system—the large sample. Dec 11, 2017 ...
