Lateral root emission in woody taproots ofFraxinus ornusL.

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2007
Abstract We applied environmental stresses, namely dehydration, pruning and bending, to woody taproots of Fraxinus ornus L. in order to: (i) identify a method that could be applied in routine studies of lateral root development from a secondary structure; and (ii) carry out anatomical investigations to identify the tissue involved in the recruitment of
