Incidence of arthropods and phytotechnical characteristics of lisianthus under different greenhouse conditions

Abstract The use of color shading meshes is presented as a new technological approach to manage flowers and ornamental plants. Eustoma grandiflorum (Raf.) Shinners is a flower that excites interest of producers and consumers. However, there is little technical and scientific information on its production and management. We evaluated the incidence of arthropods and phytotechnical characteristics in two cultivars of cut lisianthus, under the influence of different color shading meshes in commercial greenhouse. The experiments were conducted in the company Floricultura Florist, Dois Irmãos-RS, Brazil. The experiment took place from August to December 2012 and tested the influence of shading meshes with different colors (gray, red, black, and blue) on two varieties of cut lisianthus (Mariage and Bolero White). In each treatment, the phytotechnical characteristics of the plants assessed and arthropod samples were collected. Red mesh produced the best results, and blue, the worst. Nine orders of arthropods from 24 families with different habits were observed. Diptera was the most abundant. The shading screens did not influence the number of arthropods in plants.

Romania assists at the present time to an increase of production crops for ornamental plants and as a consequence an increased demand of planting material. Thus, improvements of the current multiplication methods are sought after. Lisianthus russelianus Hook. (Eustoma grandiflorum Grise.) is a relatively new floral crop to the international market, known for beautiful flowers of various colors and for having a long vase life. This study focused on the development of an efficient protocol for rapid regeneration of this species following known basic and applied aspects of lisianthus biotechnology but exploring new potentials. In the course of experiments conducted, for in vitro multiplication there were used nodal segments (1.5 cm) with axillary buds from three F1 hybrids ‘Echo Lavender’, ‘Flamenco White’, ‘Mirage Pastel Pink’ that were inoculated on MS basal medium supplemented with 0.50 mg 1-1 TDZ, 1.0 mg 1-1 BAP and 0.50 mg 1-1 AIA. The results show that the medium with BAP was most effective for obtaining the highest shoots number compared to medium containing TDZ. For rooting induction, two different concentrations of auxin IBA 0.5 mg 1-1 and 1.5 mg 1-1 were used simultaneously on MS basal medium. The highest roots number occurred when using 1.5 mg 1-1 IBA. Both the number of shoots and rooting regeneration were dependent on the cultivar. The highest shoots number was achieved for ’Mirage Pastel Pink’ hybrid (6.91) on the medium containing 1.0 mg 1-1 BAP and 0.50 mg 1-1 IAA.

Purpose The purpose of this paper, on innovative design of traditional weft-backed woven fabric, is to investigate a design principle and method for full-backed structure with double-faced shading effect to realize two types of double-faced shading effects for traditional weft-backed fabric that are impossible to be realized under plane design mode. In addition, the study on the color rendering law is conducive to the design application, and the effectiveness of the design method has been verified by the design practices. Design/methodology/approach This paper presents a design method for full-backed structure with two shaded weave databases (SWDs) by selecting two primary weaves (PWs), establishing the corresponding SWDs, selecting the proper compound structures for database of full-backed structure with double-faced shading effect. Color card fabric with 544 specimens is produced and their color values are measured, their color difference and variance are analyzed to evaluate the color rendering characteristics. Finally, double-faced weft-backed fabrics are produced under layered-combination design mode to verify the practicality of full-backed structure with double-faced shading effect. Findings Weft-backed woven fabrics with “SPDC” (same pattern and different color) and “DPDC” (different pattern and different color) shading effects can be produced using full-backed structure with double-faced shading effect. The color expression is extremely enhanced (136 compound structures on one side for one color weft). In the shading process, two sets of wefts do not affect each other, and stable and ideal color shading effect with high color purity can be expressed according to the analyses on the L* (lightness) values, color purity, color differences (0.47–3.20) and variance (0.25–1.21) of the color card fabric. Originality/value Breaking through the structural limitations and achieving the double-faced shading effects that cannot be expressed in plane design mode. The research on two weft-backed fabric with the most basic weft-backed structure provides not only a theoretical base for further study on weft-backed structures, but also some references for structure innovation design of traditional weft-backed woven fabrics.

Forest Ecosystem Services

This chapter deals with scientific information about the wild socioeconomic plants used by the local inhabitants of the Champawat district of Uttarakhand for the enhancement of their livelihood. During this entire study, it was observed and documented that poor rural people of this area are educationally and financially backward, and they do not have any permanent source of income; due to this reason they are unable to fulfill their necessary requirements. Therefore, they are totally dependent on various forest ecosystem services, viz., selling prepared herbal medicines, wild edible fruits, and wild ornamental plants, etc., which shares approximately 45-50% of their total annual income and plays a vital role for the upliftment of their livelihood. During this research work, a total of 63 plant species belonging to 58 genera under 46 families have been documented, which are being used as livelihood resources by the locals of this area.

K Concentration

Irrigation water high in alkalinity can severely compromise the growth and marketability of ornamental plants. In the present study we investigated the response of lisianthus to increased calcium (Ca) when irrigated with solutions containing high levels of bicarbonate (HCO3−)-induced alkalinity. Alkalinity in irrigation water reduced the growth of lisianthus; however, plants supplemented with an increased concentration of Ca at alkalinity levels from 4 to 7 meq·L−1 of HCO3– exhibited improved growth and dry mass (DM) accumulation or were not detrimentally affected, demonstrating that Ca contributes to the increase of the tolerance of lisianthus to alkalinity. Supplementary Ca did maintain a high stomatal conductance (gS) and transpiration rate when alkalinity was at 4 meq·L−1, which explained the lower water potential in young leaves. Plants irrigated with solutions containing supplementary Ca had higher total DM, which was associated with a higher gS; however, when conductance was higher than 0.280 cm·s−1, like in plants with no supplementary Ca, DM tended to decrease. At a typical Ca concentration, there was a disruption on stomata functioning as gS and transpiration rate increased, which was associated with a reduction in shoot potassium (K). Calcium ameliorated the uptake of K when alkalinity was 4 meq·L−1 by allowing a less marked reduction in shoot K concentration. Chlorophyll was reduced by increasing alkalinity as a result of a decrease in shoot iron (Fe); however, supplementary Ca also contributed in increasing plant tolerance to alkalinity at 4 meq·L−1 by sustaining a high shoot Fe concentration. Supplementary Ca increased catalase and peroxidase activities, indicating that lisianthus responded to the stress by enhancing the activity of these enzymes to reduce oxidative damage.
