“…No differences were observed for leaf number among the different light treatments, and our results are similar to those reported in bananas [35] and Cymbidium. However, in similar studies with banana and Anacardium othonianum plantlets, a higher number of leaves was observed under fluorescent lamps [15,30,36]. However, strawberry in vitro plantlets showed a higher number of leaves in plantlets cultured under LED compared to fluorescent lighting [37].…”

Light-emitting diodes (LEDs) have become very popular for the production of horticultural crops. LEDs represent an alternative lighting source to regular fluorescent (FL) bulbs, increasing the quality of plants and minimizing production costs. LEDs also provide selective light intensity and quality, suitable for commercial micropropagation. The objective of this study was to evaluate the growth and development of in vitro ornamental bananas under different light sources. Two ornamental banana varieties were selected for this study: Musa ‘Little Prince’ and Musa ‘Truly Tiny’. Light quality and intensity of three different light sources were evaluated: LED-1 (116 μmol m−2 s−1), LED-2 (90 μmol m−2 s−1), and FL (100 μmol m−2 s−1). Length and biomass of plantlets were greater under LED-1 compared to FL but not significantly different from LED-2. The fresh and dry weight of shoots and roots, number of leaves, and number and length of roots were not significantly different between treatments. Chlorophyll content was greater under LEDs. Leaf number and stomata number and size were greater under FL. Our results indicate that shoot length and biomass could be improved by optimizing light quality and intensity. Different responses to light sources between the two banana varieties also indicated a genotype effect.

Applying elicitors in plants growing under natural conditions change the metabolic content of volatile compounds extracted from their tissues. Here, we have investigated how abiotic elicitors influence the volatile composition of the ethyl acetate extract of Anacardium othonianum seedlings propagated in vitro and ex-vitro cultures. Abiotic factors such as salicylic acid, silver nitrate, light quality, and cultivation mode affected the composition of volatile compounds in ethyl acetate extract of A. othonianum leaves seedlings. GC/MS analysis demonstrated that α-tocopherol was the main metabolite in cultures added with chemical elicitors, reaching 22.48±4.06% in the case of 30 µM salicylic acid. Higher concentrations of salicylic acid decreased the amount of αtocopherol. The addition of AgNO3 had a linear effect on α-tocopherol. Thus, the production of this metabolite indicates that salicylic acid and AgNO3 elicitors positively affect α-tocopherol production at specific concentrations helping to understand how plant culture can be better manipulated.
