Although the presence of root anatomical structures of young Pinus ponderosa seedlings grown in containers of contrasting volume (164 vs. 7000 cm3) was similar, seedlings reared 60 days in the large container had more vascular cambium although the xylem thickness was similar. In addition, seedlings in large containers had nearly twice as many resin ducts within the vascular cambium as their cohorts in small containers. Taproot length closely matched container depth. Though lateral root emission rates were similar between container sizes, large container seedlings had more than 2X the number of lateral roots as those from small containers. These differences in morphophysiological characteristics may be important to seedling establishment on sites that experience dry summer conditions, or for seedlings destined to drier, harsher sites. Further work to elucidate the ramifications of these morphophysiological differences on seedling establishment is warranted.

Author Biography

Antonio Montagnoli, Department of Biotechnology and Life Science, University of Insubria, Via Dunant, 3 – 21100 Varese, Italy.

Antonio’s work focusses upon the morpho-physiological responses of vegetation to environmental and anthropogenic drivers such as soil erosion, landslide, rainfall and forest management. In particular he studies the variation of fine roots dynamics during these responses at both single-tree and community level. His research group is interested in a number of topics such as LED-light influence on plant growth, plant phenotyping methods to improve efficiency in filed applied science, root system soil strengthening, and vegetation analysis trough remote sensing. His research activity is documented by peer-review scientific publications, posters- and oral-presentations in international meetings. After graduation in Environmental Science at University of Molise he obtained a PhD in Environmental Botany at University of Insubria where at present holds a staff member position in the Department of Biotechnologies and Life Science of University of Insubria (Varese – Italy).
