... H. undatus is an epiphytic, fast-growing, climbing vine of the family Cactaceae. Being a CAM (Crassulacean acid metabolism pathway) plant, it has a high drought tolerance ability (Trindade et al. 2023) and is suitable for cultivation in degraded land areas. Stems are green, fleshy, jointed, and are usually three-sided. ...
Dragon fruit (Hylocereus spp.), referred to as ’Kamalam’ in India, has gained popularity in recent times due to its unique appearance, nutritional benefits, and stress tolerance/resistance. Hylocereus undatus, H. monacanthus, and H. megalanthus are the major dragon fruit variants cultivated globally. India has embraced dragon fruit cultivation, expanding its area and production through several government initiatives and research institutes. Being introduced in the 1990s, there is a dearth of information about the production technology of dragon fruit cultivation. The present review highlights the advancements in cultivation techniques assessing various aspects such as planting techniques, propagation, training and pruning, irrigation, nutrient management, and harvesting practices of dragon fruit.
... 3,4 However, the pitaya S. undatus is one of the pioneer species distributed throughout the world. 5 Recently, some in vitro and in vivo research studies have demonstrated the potent health-promoting effects of pitaya peels or their extracts, including antioxidant, antimicrobial, anticancer, anti-obesogenic, antidiabetic, anxiolytic, anti-inflammation, anti-aging, whitening, photoprotective and ameliorating ALD properties. 6 Supercritical CO 2 is a green selective technique generally used to recover polar compounds, such as essential oils. ...
BACKGROUND
Pitaya is a fruit with high consumer acceptance and health benefits. Pitaya peel is a waste product with potential in the food industry, as an antioxidant enrichment and natural colouring. Therefore, there is an interest in recovering its constituents and searching for pitaya species with greater potential. This work aimed to obtain bioactive extracts from the dried peel of pitaya fruits of the species Selenicereus monacanthus (Lem.), S. costaricensis W. and S. undatus H. using supercritical fluids at different pressures (100, 250 and 400 bar) and ethanol–water 15% v/v or ethanol 100% as co‐solvents. The extraction yield, antioxidant activity, colour and total betalain content were evaluated.
RESULTS
The extract obtained from S. monacanthus showed the highest extraction yield (49.6 g kg⁻¹), followed by S. costaricensis (27.5 g kg⁻¹) and S. undatus (17.7 g kg⁻¹) at 400 bar and 35 °C using ethanol 15%, v/v. The antioxidant capacity was strongly influenced by pressure, favouring the obtaining of betalain‐rich extracts at higher pressures, especially in the species S. costaricensis (0.6 g kg⁻¹) and S. monacanthus (0.3 g kg⁻¹). To improve the extraction of S. undatus (the most cultivated species), the procedure of subsequential extractions was applied. This procedure considerably increased the extraction yield, antioxidant activity and total content of betalains. The use of ethanol 100% provided more bioactive fractions and achieved a good separation of betalains.
CONCLUSION
The supercritical extraction method can overcome the challenge of efficiently extracting compounds from pitaya peel, due to the presence of bioactive compounds of great polarity. © 2024 Society of Chemical Industry.
... The selection of pollen source has a notable impact on fruit size, shape, color, sweetness, and overall quality, leading to combinations that enhance taste and appearance. Additional investigation in this field could reveal the functional attributes, nutritional composition, shelf life, fruit dimensions, and productivity of dragonfruit influenced by metaxenia (Trindade et al. 2023). ...
Metaxenia, an intriguing phenomenon in fruit crops, refers to the influence of the pollen parent on fruit characteristics beyond the maternal plant’s genetic makeup. This phenomenon holds significant implications for fruit crop production and improvement. Through a range of scientific studies, it has been observed that metaxenia can lead to diverse changes in fruit attributes such as size, color, flavor, and nutritional content. The practice allows for rapid trait enhancement, targeted breeding, and customization of fruit varieties to align with consumer preferences and market trends. Further, trials are required to examine the impact of varying pollen origins on biochemical processes linked to fruit quality. Additionally, identifying optimal pollinators for specific cultivars is essential. There exists a necessity to ascertain the physiological and genetic underpinnings of metaxenia concerning both qualitative and quantitative attributes in fruit crops. This paper delves into the practical implications of metaxenia, highlighting its role in shaping modern fruit cultivation, fostering innovation, and meeting the evolving demands of consumers and markets.
... Originating from tropical forests of Mexico and South and Central America (Shah et al. 2023), the consumption of in natura and processed fruits is on the rise in American, Asian and European markets (Mercado-Silva 2018). However, it is worth highlighting that these Cactaceae are still in the process of domestication and the conservation of genetic resources is of fundamental importance for genetic improvement programs (Morillo et al. 2022;Trindade et al. 2023). ...
Endoreplication is a process by which cells replicate their genomes without mitosis, resulting in an increase in nuclear DNA ploidy. This study is the first to report that oxidative stimuli from cryopreservation of seeds in liquid nitrogen induces endoreplication. We list evidence that the cryopreservation of red pitaya seeds (Hylocereus costaricensis) in liquid nitrogen for 30 and 60 days induced genome duplication stimuli via endoreplication. It was demonstrated that this conservation technique modulates the levels of hydrogen peroxide (H2O2) and antioxidant enzymes, triggering oxidative stimuli. The flow cytometry analysis of cladodes revealed different levels of ploidy between the tissues (mixoploidy) and that seedlings from the longest cryopreservation times of seeds showed higher percentages of octoploid nuclei when compared to the control treatment. The cryopreservation of seeds for 60 days also allowed increases of approximately 130% in seedling biomass, which is possibly related to the increases in ploidy levels resulting from endoreplication. It was also shown that cryopreservation of seeds with cryoprotectant solutions (PVS2) increases the efficiency of antioxidant metabolism in eliminating H2O2, repressing oxidative signalling and consequently endoreplication, maintaining ploidy levels and stable growth patterns.
