Application of Wireless Power Transmission Led Lighting System in Propagation of Chrysanthemum and Strawberry Planta Daninha
NAM,N.B.; HUY,N.P.; LUAN,V.Q.; TUNG,H.T.; NHUT,D.T..
ABSTRACT Wireless power transmission has been recently used to charge batteries in portable devices. This is the first study to combine this technology with light-emitting diodes (WPT-LP) for plant tissue culture application. We also present the comparison of the in vitro growth of chrysanthemum and strawberry plantlets under the new LED lighting system; LED - Uni-Pack (LP) system; LED tube and fluorescent light (FL). The results showed that fresh weight (1.42 g), dry weight (118.67 mg), plant height (5.68 cm), leaf area (3.59 cm2) and chlorophyll content (47.9 μg g-1) of chrysanthemum plantlets under the WPT-LP system were higher than those under FL and LED tube. Similar results were also recorded on the strawberry plantlets. Our results suggested that...

Light spectral quality on production of lettuce, cucumber and sweet pepper seedlings Sci. Agrar.Paran. / SAP
Silva, Eliamara Marques da; Costa, Geany Giovana Silva da; Andrade, Agner Freitas; Ferreira, Hellen Cristina Pereira; Steiner, Fábio.
The response of lettuce (Lactuca sativa), cucumber (Cucumis sativus) and sweet pepper (Capsicum annuum) seedlings to light spectral quality when grown under continuous illumination was investigated in relation to the growth, dry matter, and seedling quality index. Different light quality treatments were applied during the germination and plant growth steps, using cool-white fluorescent bulbs (CWF) or red and blue light-emitting diodes (LEDs) at an fluence of 30 and 25 μmol m-2 s-1 photosynthetic photon flux density (PPFD), respectively. Treatments were arranged in a completely randomized design in a 3×2 factorial: three vegetable species (lettuce, cucumber and sweet pepper) and two light quality treatments (white fluorescent light or red and blue LEDs),...

Calidad de la luz led y desarrollo in vitro de Oncidium tigrinum y Laelia autumnalis (orchidaceae) Agrociencia
Murillo-Talavera,Martha M.; Pedraza-Santos,Martha E.; Gutiérrez-Rangel,Nicolás; Rodríguez-Mendoza,María de las N.; Lobit,Philippe; Martínez-Palacios,Alejandro.
Resumen La calidad, intensidad y duración de la luz afectan el desarrollo vegetal porque promueven diferentes respuestas fisiológicas. El objetivo de esta investigación fue evaluar la influencia de distintos espectros de iluminación sobre el desarrollo in vitro de Oncidium tigrinum La Llave y Lex. y Laelia autumnalis (Lex.) Lindl. Plántulas de tres meses de edad se cultivaron en medio Murashige y Skoog sin fitohormonas más tiamina (0.4 mg L-1), inositol (100 mg L-1), sacarosa (30 g L-1), agar (6 g L-1) con pH de 5.7. El diseño experimental fue completamente al azar y la unidad experimental consistió de 30 plántulas. Los tratamientos fueron LEDs rojo y azul en proporción 3:1, 2:2 y 1:3, LEDs blancos y luz blanca fluorescente (testigo), con seis repeticiones...
