Significats de adventitious root en anglès

Although various factors influence adventitious root formation, little is known of the associated regulatory mechanisms.

Results: Temporal patterns of gene expression were determined in the base, the middle, and needles of cuttings at eight time points during adventitious root formation.

CO aqueous solution treatment was able to ameliorate the ZnPPIX-induced inhibition of adventitious rooting.

Conclusions: Structural modifications of adventitious roots suggest increased contribution of apoplastic bypass to water flow.

Background: Adventitious root formation is an essential physiological process for successful propagation of cuttings in various plant species.

Indole acetic acid (IAA) is an important regulator of adventitious rooting via the activation of complex signaling cascades.

In the present study, we examined structural and functional modifications in adventitious roots of tamarack seedlings to explain their flooding tolerance.

The adventitious roots in flooded plants also exhibited retarded xylem and endodermal development and accumulated numerous starch grains in the cortex.

In many Dicotyledons and most Monocotyledons, the primary root soon perishes, and its place is taken by adventitious roots developed from the stem.

Whereas adventitious roots generally form from the base of cuttings, this process is accompanied by physiological changes in leaves, which supply assimilates and metabolites.

The single stem of youth frequently deteriorates and occasionally disappears altogether, adventitious roots, descending from various heights, forming an elaborate and sure and ever-developing support.

Background: A lack of competence to form adventitious roots by cuttings of Chrysanthemum (Chrysanthemum morifolium) is an obstacle for the rapid fixation of elite genotypes.
