, and lignification of more than 50% of the stele. Adventitious root counts in the proximal two nodes were recorded for each sampling date. For the purpose of this study, we used “regular vascular cambium” following the terminology of Wilson and Lowe
talc dip. On each chart, treatments not sharing a letter in a year are significantly different according to a Tukey honestly significant difference test at P < 0.05 ( n = 7); 1 ppm = 1 μg·g −1 , 1 cm 2 = 0.1550 inch 2 . Table 2. Adventitious rooting
adventitious rooting is important in identifying practical methods to optimize plant stand and production efficiency. The role of plant hormones in adventitious rooting has been a source of confusion not only in sweetpotatoes but in other plant species as well
used for D. caryophyllus seedling production, which is economically important for high-scale breeding of elite commercial genotypes from stem cuttings of the mother plants ( Garrido et al., 1998 ). Adventitious rooting is an essential step in the
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
The relationship between auxin and adventitious root formation has been studied for many years. Indole-3-acetic acid plays a central role in adventitious rooting and was the first plant hormone used to stimulate the rooting of cuttings ( Cooper
( Marler and Cruz, 2017 ) because excavation of intact roots for traditional transplant operations was cost-prohibitive. This unprecedented attempt to initiate adventitious roots on large cycad stems resulted in 41% success in adventitious root formation

in the asexual propagation literature. Our objective was to determine the influence of IBA concentrations of 0 to 30 mg·g −1 on the success and speed of adventitious root formation on Z. furfuracea and Z. integrifolia stem cuttings. Materials and
