expression of several genes, which are influenced by several environmental factors ( Ravi et al., 2009 ). Transplanted slips produce adventitious roots, some of which develop into economically important storage roots through proliferation of cambial cells

Adventitious root formation (ARF) is the process by which roots arise from nonroot plant tissue ( Bellini et al., 2014 ; Davis and Haissig, 2013 ). Effectively using ARF for plant propagation is a cornerstone of the ornamental horticulture industry

flow should be carefully considered for the stable formation of adventitious roots, which is essentially required to produce healthy, independent plants ( Christiaens et al., 2015 ). The development of adventitious roots also has been shown to be auxin

some concern regarding the root structure of plants propagated by vegetative methods. Propagation through cuttings and TC will generate a root system that is largely composed of adventitious or lateral roots, compared with seed propagation, which will

sweetpotato crop in a closed environment. Of particular importance to this crop is the rapid growth of adventitious roots because these will influence the eventual development of storage roots. If sweetpotato is to be used successfully in future

weekly hand misting. Both cultivars produced adventitious roots within 10 to 14 d, with most of the roots forming at the base of the bud. Soon after root formation, a flower shoot emerged from the axillary bud; ≈2 months later, the flowers on the

reported to be as good as rooting under intermittent mist in some thornless blackberry ( Zimmerman et al., 1980 ). In a preliminary study, several adventitious roots developed at the base of most axillary buds on five-node hardwood cuttings of ‘Siskiyou
