Varietal Performance of Anthurium (Anthurium andreanum) on Growth and Flowering in the Subtropical Zone of West Bengal

An investigation was conducted to evaluate genotypes of Anthurium by maintaining in the pot at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, West Bengal during three consecutive years 2015-16, 2016-17 and 2017-18. The experiment was laid out in Complete Randomized Design (CRD) with fourteen anthurium cultivars and replicated thrice. Significant differences were found between all the parameters studied. From the pooled data of three years, it was observed that Tropical Red, Agnihotri and Marina recorded better suckering ability. The highest plant height was recorded in Tropical (42.4 cm) closely followed by KalingPong Pink (41.2 cm) and Nitta (39.8 cm). A maximum number of flowers plant-1 year-1 was noticed in Tropical (8.3) and lowest in Alexis (2.1). Ozaki Red recorded the largest flower (9.5 x 7.6 sq. cm), which was followed by Tropical (9.02 x 8.6 sq. cm), Tinora (8.9 x 7.3 sq. cm), and Alexis (8.9 x 8.6 sq. cm). The longest flower spike length was observed in Agnihotri (38.2 cm) followed by Tropical. Spike extended maximum vase life in Pistache (10.1 days) closely followed by Tropical (9.9 days). Overall, among the fourteen cultivars, Tropical was the best cultivar regarding both yield and quality flower production for commercial cultivation in the sub-tropical conditions of West Bengal.

Biodiversity, management, and commercialization of ornamental plants at nurseries in Fortin de las Flores, Veracruz

Objective: The aim of this study was to create an inventory of the biodiversity, management, and commercialization of ornamental plants at nurseries in the municipality of Fortín de las Flores in the State of Veracruz, Mexico. Design/methodology/approach: Semi-structured interviews were carried out with 150 nursery owners. Results: The respondents reported a total of 230 different plants. With regard to commercialization, 20 species were reported as the most sold. The most notable species were: Syagrus romanzoffiana (Cham.) Glassman, Caesalpinia echinata Lam., Anthurium andreanum Linden, and Phoenix roebelenii O’Brien. The biggest problem was the sale price; 65% of the nursery owners reported that they sold their plants to strangers, and that they did not belong to any organization or cooperative. Limitations on study/implications: The poor local technological development characterized by unspecialized small and medium-sized businesses that compete with each other with little trade organization is a result of the sociocultural context of the region. This context limits regional development. Therefore, more research regarding sociocultural aspects should be promoted. Findings/conclusions: We have concluded that there is an underutilization of the native agrobiodiversity, since species originating in other parts of the world are what is most often sold. This is evidenced in the main species sold as well as those that generate the highest profits for the nursery owners.

Effect of Foliar Spray of Primary Nutrients and their Frequency on Anthurium (Anthurium andreanum L.) var. Xavia under Protected Condition

The experiment was conducted under protected conditions at the Polyhouse Complex, Department of Horticulture (Veg. and Flori.), Bihar Agricultural University, Sabour, Bhagalpur, Bihar during the year 2016-2017. The experiment was laid out in Factorial Completely Randomized Design with three replication and 10 treatment combinations, comprising five levels of water soluble fertilizer (1 g/l, 2 g/l, 3 g/l, 4 g/l and 5 g/l) and two frequencies of spray (once a week and twice a week). Plants were maintained in net house conditions (75% shade). The result indicated that among all treatment combinations, D5F2 (NPK 19:19:19 @ 5 g/l twice a week) found to be best in terms of vegetative growth, flowering and productivity of anthurium var. Xavia as it recorded maximum values for all the characters. The treatment combination D5F2 (NPK 19:19:19 @ 5 g/l twice a week) recorded maximum length and breadth of leaf (26.02 cm and 15.48 cm, respectively), plant spread east to west and north to south (62.67 cm and 62.37 cm, respectively), petiole length (36.76 cm), flower stalk length (29.17 cm), spathe length and breadth (9.61 cm and 8.30 cm, respectively) and higher yield of flowers per plant (4.13). It required minimum days (90.93 days) for first flower opening. Hence considering the positive effects on growth, flowering, yield and quality, the treatment combination D5F2 (NPK 19:19:19 @ 5 g/l twice a week) can be considered for adopting at the field level to get better qualitative and quantitative yield.

biofábricas y biorreactores de inmersión temporal: propagación in vitro de Anthurium andreanum L., y su viabilidad económica

Objetivo: Evaluar la viabilidad técnica y financiera para la implementación de una biofábrica para la propagación in vitro de Anthurium andreanum L. Diseño/metodología/aproximación: El experimento tuvo una distribución completamente al azar. Los datos se sometieron a un análisis unidireccional de varianza (ANOVA), las medias se compararon mediante la prueba de Duncan (P ? 0,05). Con el fin de calcular la viabilidad económica de la Biofábrica, se determinaron los indicadores de Punto de Equilibrio, Relación Beneficio/Costo, el Valor Actual Neto (VAV) y la Tasa Interna de Retorno (TIR). Resultados: En este estudio se utilizó el SIT comercial Recipiente de Inmersión Temporal Automatizado (RITA®). Se obtuvo una tasa promedio de multiplicación de 26.4 brotes por explante utilizando medio líquido suplementado con 2 mg L-1 de 6-bencilaminopurina. Para el establecimiento de la biofábrica se utilizaron 210 RITA®, con una capacidad instalada para obtener aproximadamente 400,000 plántulas al año. Al realizar el análisis financiero de esta técnica, arrojó una Tasa Interna de Retorno de 73.64% y una Relación Beneficio Costo de 1.67 y un Valor Actual Neto de MEX $ 2, 513,056.14 pesos mexicanos (US$ 131230.08), en un periodo de 5 años. Con estos resultados se demostró la viabilidad económica y técnica para la implementación de una biofábrica productora de anturios. Limitaciones del estudio/implicaciones: Utilizar medios de cultivo semisólidos en la etapa de multiplicación, disminuye la capacidad de producción y baja de manera significativa la rentabilidad de la biofábrica. Hallazgos/conclusiones: La rentabilidad de una biofábrica para la producción de anturios depende de la tasa de multiplicación, alcanzada en este caso a través del uso del RITA®, actualmente se cuenta con la tecnología completa y comprobada para ser transferida a algún emprendedor interesado.
