摘要: To identify the importance of arbuscular mycorrhizal fungi (AMF) colonizing wetland seedlings following flooding, we assessed effects AMF on seedling establishment two pioneer species, Bidens frondosa and Eclipta prostrata grown under three levels water availability ask: (1) Do inoculated differ in growth development from non-inoculated plants? (2) Are inoculation degree colonization dependent availability? (3) plant responses to between closely related species? Inoculation had no detectable shoot height, or biomass but did affect partitioning root morphology a species-specific manner. Shoot/root ratios were significantly lower E. plants compared with (0.381 ± 0.066 vs. 0.683 ± 0.132). Root length surface area greater (259.55 ± 33.78 cm 194.64 ± 27.45 cm 54.91 ± 7.628 cm2 46.26 ± 6.8 cm2, respectively). effect B. length, volume, area. associations formed at all availability. Hyphal, arbuscular, vesicular dry intermediate flooded treatments. Measures responsiveness depressed for total fresh weight (−0.3 ± 0.18 g 0.06 ± 0.06 g), (−0.78 ± 0.28 cm vs.−0.11 ± 0.07 cm), volume (−0.49 ± 0.22 cm3 0.06 ± 0.07 cm3), (−0.59 ± 0.23 cm2 vs.−0.03 ± 0.08 cm2). Given disparity species response inoculation, events that alter prevalence wetlands could community structure by directly affecting development.
