“…However, the response of different plant species to light, including green and yellow light, can be different. Contrary to previous results, green light stimulated leaf area growth of Capsicum annuum plants (Casierra-Posada et al 2014), and shoot growth in Lactuca sativa (Johkan et al 2012). In Solanum tuberosum the addition of yellow light improved vegetative growth (Li et al 2018).…”

Lilium candidum L. is a plant with rich cultural traditions and huge potential in floriculture and modern medicine. Our study analyzed the effects of light emitting diodes (LEDs) of variable quality on adventitious organogenesis induced in bulb scales placed on Murashige and Skoog medium. In addition to the spectral compositions of red (100%), blue (100%), and red and blue light (RB ratio 7:3), RB light was mixed in equal proportions (50%) with green (RBG), yellow (RBY), UV (RBUV), and far red (RBfR) light. We also tested white LED (Wled). Fluorescent lamp light (Fl) and darkness (D) served as controls. We assessed the effects of light on the morphometric features as well as the physiological and biochemical quality of the bulblets (adventitious bulbs). Bulb formation was observed under all light qualities, even in darkness, albeit to a limited extent. White LED light (Wled) treatment translated into the highest efficiency of bulblet formation and the greatest number of bulbs with developed leaves. The leaves, even though the shortest ones, also developed as a result of RBG treatment, and this light mixture enhanced the diameter of the forming bulblets. The bulbletsunder this light spectrum accumulated the most chlorophyll and carotenoids. The bulblets formed under B, RBfR and RBG LED had more than two times higher phenoliclevels than those formed under R LED and Fl. The bulbletsformed under B LED were the richest in soluble sugars, similarly to those developing in darkness (D).

“…In contrast, the number of leaves/plant and the thickness and area of the leaf blade in A. brasiliana (Macedo et al, 2011 ) and balloon flower (Liu et al, 2014a ) were the greatest in plants grown under blue light than plants grown under other lights, but blue light did not affect total dry matter production in roses (Terfa et al, 2013 ). Exposure to green and red light also produces the smallest leaf area in A. brasiliana (Macedo et al, 2011 ); however, in bell pepper plants, the leaf area was greater under green covers (Casierra-Posada et al, 2014 ). After exposure to a short-duration of blue light from LEDs, the levels of shoot tissue pigments, glucosinolates, and mineral elements were obviously increased in sprouting broccoli ( Brassica oleacea var.…”

Using an RNA sequencing (RNA-seq) approach, we analyzed the differentially expressed genes (DEGs) and physiological behaviors of “Manicure Finger” grape plantlets grown in vitro under white, blue, green, and red light. A total of 670, 1601, and 746 DEGs were identified in plants exposed to blue, green, and red light, respectively, compared to the control (white light). By comparing the gene expression patterns with the growth and physiological responses of the grape plantlets, we were able to link the responses of the plants to light of different spectral wavelengths and the expression of particular sets of genes. Exposure to red and green light primarily triggered responses associated with the shade-avoidance syndrome (SAS), such as enhanced elongation of stems, reduced investment in leaf growth, and decreased chlorophyll levels accompanied by the expression of genes encoding histone H3, auxin repressed protein, xyloglucan endotransglycosylase/hydrolase, the ELIP protein, and microtubule proteins. Furthermore, specific light treatments were associated with the expression of a large number of genes, including those involved in the glucan metabolic pathway and the starch and sucrose metabolic pathways; these genes were up/down-regulated in ways that may explain the increase in the starch, sucrose, and total sugar contents in the plants. Moreover, the enhanced root growth and up-regulation of the expression of defense genes accompanied with SAS after exposure to red and green light may be related to the addition of 30 g/L sucrose to the culture medium of plantlets grown in vitro. In contrast, blue light induced the up-regulation of genes related to microtubules, serine carboxypeptidase, chlorophyll synthesis, and sugar degradation and the down-regulation of auxin-repressed protein as well as a large number of resistance-related genes that may promote leaf growth, improve chlorophyll synthesis and chloroplast development, increase the ratio of chlorophyll a (chla)/chlorophyll b (chlb), and decrease the ratio of carbohydrates to proteins in plants. Although exposure to red and green light seems to impose “shade stress” on the plantlets, growth under blue light is comparable to growth observed under white or broad-spectrum light.

“…Santos y Salame (2012) encontraron que en arándano (Vaccinium oxycoccus) bajo un túnel de polietileno con 35% de sombreado se tuvo incremento de la floración, mayor peso del fruto y rendimiento en comparación que con cielo abierto. Casierra et al (2014) observaron que para chile pimiento (Capsicum annuum) el mayor contenido de clorofila se observó en las plantas bajo las cubiertas de polipropileno de color azul, verde y transparente, con respecto al observado bajo las cubiertas de color amarillo y rojo.…”

Objetivo. Evaluar agronómica y fisiológicamente el desarrollo de cultivares de lechuga en condiciones protegidas. Materiales y métodos. Bajo un diseño en bloques completamente al azar se evaluó el crecimiento, las características agronómicas y fisiológicas de cinco cultivares de lechuga en dos sistemas de agricultura protegida y en condiciones de campo abierto. Resultados. Los cultivares White Boston y Romana Parris Island Coss en casa malla y campo abierto tuvieron los mayores valores en variables fisiológicas (fotosíntesis cerca de 25.00 µmol CO2 m2 /s, transpiración mayor a 7.00 mmol agua m 2 /s y conductancia estomática mayor a 1.50 mmol agua m 2 /s), lo que provocó los mayores valores en biomasa fresca área y raíz (95.90 y 3.55 g, respectivamente). La variable fotosíntesis en plantas sembradas en campo abierto alcanzaron valores de 22.29 µmol CO2 m 2 /s, comparado con casa malla e invernadero con 17.14 y 14.16 µmol CO2 m 2 /s. Conclusiones. La capacidad de estos cultivares de lechuga a tolerar estrés por calor se debió a mecanismos morfológicos y fisiológicos, entre ellos, hoja de larga vida, control estomático y alto potencial fotosintético.
