“…In experiments with other fruit trees, such as the pineapple cultivar 'Vitória', the sprout survival in culture media with different structuring agents, such as pure maize (Zea mays) starch oragar with partial or total addition of starch, did not differ from that in agar media. Thus, plants cultivated in environments with corn starch showed a similar development to those cultivated in agar (OLIVEIRA et al 2015a).…”

“…In order to reduce the costs of micropropagation, research to replace reagents such as agar with alternative solidifying materials for culture media that also allow for adequate development of the explants has been conducted. For example, GOLLE et al (2010) experimented with corn starch, vermiculite, filter paper, and hydrophilic cotton for micropropagation of the loblolly pine (Pinus taeda), CURTI & REINIGER (2014) tested vermiculite, Plantmax ® , and fine sand in yellow poinciana (Peltophorum dubium), OLIVEIRA et al (2015aOLIVEIRA et al ( , 2015b tested corn starch and cassava starch in pineapple (Ananas comosus), andRODRIGUES et al (2016) andNADAL et al (2018) assessed the use of coconut fiber, carbonized rice husk, and in natura rice husk for propagation of golden rain orchid (Oncidium baueri).…”

Concentrations of cytokinin and the use of agricultural residues in the in vitro propagation media of highbush blueberry

et al. 2020

The objective of the research was to evaluate cytokinin concentrations and agricultural residues as physical structuring agents of the culture medium in the in vitro propagation of highbush blueberry (Vaccinium corymbosum ‘Duke’). To that end, three different concentrations of 2-isopentenyladenine (2iP) (0, 5, and 10 mg L-1)in woody plant medium (WPM) and five structuring agents (in natura rice husks, carbonized rice husks, coconut fiber, S-10 Beifort®, and agar)were tested. After 60days of culture, the following parameters were evaluated: survival (%),sprout and shoot lengths (cm),propagation rate, number of sprouts, and shoot dry mass (g). The substrates used as structuring agents were analyzed in terms of pH and electrical conductivity. The in natura rice husk, S-10 Beifort®, and carbonized rice husk did not differ from the agar in terms of the sprout length. The shoots were longer (1.64 cm) in cultures within natura rice husk than in other treatments. In the absence of 2iP, S-10 Beifort® resulted in the highest propagation rate (2.97). Concerning the number of sprouts, S-10 Beifort®, in natura rice husks, and carbonized rice husks did not differ from agar. However, when the regulator was added, the agar performed better in comparison to the other residues. Thus, in natura rice husks, carbonized rice husks, and S-10 Beifort®are potential physical structuring agents of the culture medium that can be used without 2iP.

“…Photosynthetic index (PI) is used to interpret responses of plants subjected to stress conditions: a PI lower than 1.0 represents a critical point (OLIVEIRA et al, 2015). This variable considers structural and functional events that occur in the PSI and PSII (GONÇALVES et al, 2005).…”

Pineapple is a tropical fruit with high demand by the fruit market in Brazil. Fruits of the cultivar ´Turiaçu` stans out in local consumer markets due to its excellent quality. The objective of this work was to evaluate ecophysiological responses of ´Turiaçu` pineapple plants at the vegetative and reproductive stages to soil fertilization and crop location, and their effects in fruit yield. The study was conducted in the cities of São Luís and Turiaçu, MA, Brazil. Plants under mineral and organic fertilization in two locations, São Luís and Turiaçu, and in two seasons, dry and rainy season, were evaluated during dry and rainy seasons. Chlorophyll index, photochemical efficiency, gas exchange, and fruit yield were evaluated. The pineapple plants presented decrease in the photosynthetic activity, at both developmental stages and in both seasons, when grown in São Luís. The CO2 photosynthetic assimilation decreased. The PSI and PSII activity, according with photosynthetic index, was more sensitive at the reproductive than at the vegetative stage. The organic fertilization was not appropriate for the ´Turiaçu` pineapple crops, regardless of the crop location. The fruit yields were 54.4% and 57.9% lower in São Luís, under mineral and organic fertilization, respectively. Thus, the ecophysiology of ´Turiaçu` pineapple was more affected by water availability than by soil fertility in the municipality of Turiaçu.

“…Soares et al (2014) who studied in vitro cultivation of Dendrobium nobile Lindl., reported that replacing 50% of agar for maize starch provided higher plant growth in culture media sterilized by autoclaving. Studies conducted with pure maize starch or cassava starch combined with agar in culture media sterilized by autoclaving showed that they were effective in culture media solidifying agents in the in vitro rooting of 'Gold' pineapples (Oliveira et al, 2015). Vieira (2018) analyzed the hydrogel to replace agar in vitro showing potential to be used in the in vitro cultivation of A. thaliana.…”

The aim of this study was to check the use of the following gelling agents: the xanthan gum “Adicel®” and the stabilizer “Super Liga Neutra®” to replace agar in the in vitro rooting phase of Gerbera hybrida cv. Essandre. Additionally, the possibility of using chemical sterilization of both culture media and glassware with sodium hypochlorite to replace autoclaving was analyzed. The gelling agents, xanthan gum “Adicel®” and the stabilizer “Super Liga Neutra®” were tested at the following concentrations (g L-1): 7; 9; 11; 13; 15; 17; 19; and 21. No concentrations of Super Liga Neutra® provided effective solidification. Concentrations of 17 and 21 g of Adicel® provided a good gelling of the culture medium, which was compared to the medium containing agar (control) with two types of sterilization: autoclaving (for 20 and 40 minutes) and chemical sterilization. Autoclaving for 20 minutes did not provide effective elimination of contamination in the culture medium containing xanthan gum; this only occurred when autoclaving time increased to 40 minutes. Plant development in culture media containing 17 and 21 g of xanthan gum, either sterilized by autoclaving for 40 minutes or at a concentration of 17 g xanthan gum using sodium hypochlorite, was statistically the same as the control that contained agar. However, plant development at a concentration of 21g of xanthan gum in a sterilized medium using sodium hypochlorite was lower than that observed in media containing agar.
