“…Topolins, such as mTR, are considered a reasonable alternative, especially in the case of woody plants [15]. The experiments presented were tested on Handroanthus guayacan, a tropical woody tree previously called Tabebuia guayacan [16][17][18], belonging to the family of Bignoniaceae and is listed in the IUCN's Red List [19]. In the tropics, the plant is valued for its extensive yellow blooms in response to rainfall.…”

“…Worldwide, this species is valued for its olive to reddish brown wood that is internationally traded. The interest in this species dates back to pre-Columbian time (AD 880 to 1020), when its wood was utilized as grave gifts by the upper class [18]. Handroanthus wood has been found to be resistant to tropical, temperate soil pathogens [20], and marine borer insects [21].…”

An important factor affecting the uniformity of in vitro cultures is the topophysical position of the original explant. We investigated this phenomenon in Handroanthus guayacan, a tropical woody tree species. Shoots from a stock culture were separated into upper, middle and basal sections and transferred to a modified MS medium containing meta-topolin-riboside and indole-butyric acid. After 8 weeks, the middle section produced the most shoots, the longest shoots and the highest number of nodes per plant. Shoots derived from the upper section were elongated, but had the shortest internodes, while those from the basal section formed the largest callus. None of the three types of explants rooted during the proliferation phase. The topophysically dependent spatial distribution of endogenous cytokinins and auxins was determined. The topophysical effect observed could not be explained solely by analyzing the endogenous isoprenoid and auxin. However, the metabolism and distribution of the aromatic cytokinin could provide an explanation. The concentration of the meta hydroxy-substituted topolins was highest in shoots derived from the middle section. Aromatic N- and O-glucosides were much more concentrated in the leaves than in the stems. In conclusion, it is recommended to consider the explant’s topophysis when developing a multiplication protocol to avoid heterogeneity in an in vitro culture.

Effect of water deficit on water status and growth of five tropical species used in urban forestry

Due to the urban environment urban trees must deal with drier and hotter than in rural areas. Knowing the water consumption of each species and the indicators of water deficit is useful to decide the frequency and volume of irrigation and to select species according to the microclimate of the location. To determine approximately the irrigation frequency and to identify physiological variables that indicate water stress, it was carried out an experiment in which five tropical species (Citharexylum montanum M., Citharexylum sulcatum M., Caesalpinia spinosa K., Inga edulis M. and Retrophyllum rospigliosii P.) were subjected to water deficit. After a month of planting, eight trees per species were subjected to four treatments: control treatment (volumetric water content higher than 45% (TC)), the volumetric water content of 20% (VM20), fifteen and thirty days after the soil had reached VM20 (T15 and T30, respectively). In trees with similar height, it was found that the descending order of water consumption was I. edulis, C. montanum, C. spinosa, C. sulcatum, R. rospigliosii and that the best indicator of water deficit was the stem water potential. In general, volumetric moisture of soil of 20% was a suitable threshold to decide when irrigating regardless of the species. Deeming the effect of the treatments on the growth of the assessed species, T30 diminished severely the growth by 50% in comparison to the control, except for C. sulcatum in which there were no significant differences.
