NOMURA, Edson Shigueaki et al. Growth and yield of anthurium under different shading screens. Cienc. Rural [online]. 2009, vol.39, n.5, pp.1394-1400. ISSN 0103-8478.

The use of screen or plastic films of different nature or color can change the quality of spectral radiation, and as consequence the growth and production of a crop. The objective of the present research was to evaluate the growth and yield of Anthurium andraeanum 'Apalai' under different shading screens. For developing such research, micropopageted seedlings were planted in beds under four screens with 70% shading (blue, red, black and thermo-reflective). The experimental design was completely randomized, with four treatments and four repetitions. The assessments were conducted for 12 months, started after the production of flower stalks marketable. The black screen gave the best results, providing the best conditions for growth and production of anthurium, and the larger dimensions flowers stem, that are considered attributes of quality to cut flower.

Palavras-chave : Anthurium andraeanum; cut flower; flowering; colors screens; spectral quality radiation.
