The formation of adventitious
roots is a complex genetic trait regulated by interactions between environmental and endogenous factors (PACURAR et al., 2014).
Infectivity assays are routinely used to screen for the presence of infectious virus contaminants, whether these are nonspecific for the detection of adventitious
virus contaminants, or specific for the detection of specific bovine, porcine, murine or hamster viruses.
The criteria used to consider a root as new (not suberized) was the adventitious
color, as older roots presented a brownish and suberized aspect.
With respect to the induction of adventitious
shoots, it was observed that they were formed from the green spots originated from the callus formation (Figure 1H).
The in vitro aerial shoots were transferred to an induction medium for adventitious
rooting, keeping the source of explants (cotyledon segments and/or apical segments) in the absence or presence of IBA (1.5 mg [L.sup.-1]).
The proportion of patients with audible adventitious
lung sounds was significantly higher among those hospitalized for [greater than or equal to] 21 days and among those who did not survive (Table 1).
The present study was conducted to establish a propagation method for this species: a vegetative method to assess: the effect of different concentrations of an IBA phytohormone-based root enhancer, on the production of adventitious
roots in cuttings and air layers of adult plants of P.
By the systematical optimization on explants sterilizing, induction and multiplication of adventitious
shoots, rooting and seedling transplanting, the high-efficient regeneration system and domestication transplanting technology for red pitaya (Hylocereus polyrhizus) were established using dormant buds in spine base as primary materials.
