The flower of Strelitzia reginae generates abundant and viscous mucilage as exudate, which is purified in periods of heating–cooling, and finally precipitated with ethanol, obtaining strelitzia gum (StrG). By means of intrinsic viscosity measurement, the viscometric molecular weight (MWv) is determined, with a value of 200,000 g/mol, as well as a hydrodynamic radius of 20 ± 1 nm and a hydration value of 445 ± 34 g/g. The size of StrG was compared against dynamic light scattering data with a value of 16 ± 2 nm and a MWDLS of 230,000 g/mol. StrG is a biopolyelectrolyte with an “a” value of 0.85, which corresponds to a flexible behavior with a great effect of volume exclusion. This statement is based on the difficulty of gum dissolution, that should be performed at 80 °C. This macromolecule is very promising and can potentially be used in several industrial applications, such as in film forming, and as a gel, thickener, and coemulsifier.

The aim of this study was to evaluate the domestic wastewater treatment efficiency as well as the survivability of commercially valuable ornamental plants in subsurface flow wetlands (SSFW) for domestic wastewater (DWW) treatment in laboratory and pilot wetland studies. The laboratory scale study included five different species (Zantedeschia aethiopica, Strelitzia reginae, Anthurium andreanum, Canna hybrids and Hemmerocallis dumortieri) that were evaluated in horizontal flow subsurface treatment cells. All the plants survived during the 6-month experimental period demonstrating high wetland nutrient treatment efficiency. In order to validate and expand these preliminary results, a pilot-scale wetland study was carried out in SSFWs under two different flow regimes (horizontal and vertical flow). Four ornamental species were tested during a 1-year period: Zantedeschia aethiopica, Strelitzia reginae, Anthurium andreanum and Agapanthus africanus. The removal efficiencies were significantly higher in the vertical subsurface-flow constructed wetlands (VFCW) for all pollutants, except for nitrate (NO3-N), total nitrogen (TN) and total suspended solids (TSS). These results show that it is feasible to use select non-wetland plants with high market value in SSFWs without reducing the efficiency of the wastewater treatment system, although future work should continue in order to apply this technology in a large scale. The added value of floriculture in treatment wetlands can help to promote the use of constructed wetlands (CW) for domestic wastewater treatment in developing countries where economical resources are scarce and water pollution with DWW is common.

The study pertaining to the effect of summer season on correlation analysis in bird of paradise (Strelitzia reginae) was carried out among forty progenies. The results of correlation analysis for twelve parameters (plant height, stem girth, leaf length, leaf width, number of leaves per plant, number of suckers/m 2 , flower stalk length, flower stalk girth, spath length, no. of bracts, vase life and no. of flowers/ m 2 ) at genotypic and phenotypic levels revealed that number of flowers per m 2 of progenies during summer, 2011 showed positive and significant correlations with plant height (0.357 and 0.237) and number of suckers/ m2 (0.880 and 0.899). Whereas, it showed positive and significant correlation with stem girth (0.203), leaf width (0.202) and flower stalk girth (0.265) at genotypic level only. While during summer 2012, number of flowers per m 2 showed positive correlations with plant height (0.265 and 0.242), stem girth (0.232 and 0.215), number of suckers/ m 2 (0.913 and 0.900) and flower stalk length (0.268 and 0.249) at genotypic and phenotypic levels. Hence, the selection of these characters would be effective in improving yield in bird of paradise crop.
