“…In our case and in order to better identify from which part of the TCLs the embryogenic structures develop, transverse sections were obtained ( Figure 2 ). A similar pattern for the distribution of the VB toward the LM was also previously described in peach palm ( Fonseca et al, 2019 ). Higher cell density characterizes the LM, which in many cases is separated from the rest of the explant.…”

Somatic embryogenesis and plant regeneration from transverse thin cell layers of adult peach palm (Bactris gasipaes) lateral offshoots

In this work, we report a successful protocol to obtain in vitro peach palm (Bactris gasipaes Kunth) “Diamantes 10” plants through somatic embryogenesis from transverse thin cell layer (TCL) explants, dissected from three sections (basal, medial, and apical) of lateral offshoots of adult plants cultured on different concentrations of 4-amino-3,5,6-trichloropicolonic acid (picloram). After swelling and development of primary callus in all treatments, without any strong effect of explant origin or picloram concentration, it was possible to observe the formation of embryogenic structures and the exact point from where they developed. Browning was also observed and correlated to the induction treatments, although it was not an impairment for the production of embryogenic structures. Subsequent maturation and conversion of somatic embryos into plantlets allowed their acclimatization 17 months after culture initiation (ACI), which was quicker than previous reports with juvenile tissues (from embryos or seed-germinated plantlets). To the best of our knowledge, this is the first report on peach palm regeneration through somatic embryogenesis from TCL explants from adult plants and could constitute, after fine-tuning the acclimatization stage, a tool for mass clonal propagation of elite genotypes of this open-pollinated crop, as well as for the establishment of conservation strategies of in situ gene bank plant accessions endangered due to aging and other threats.

“…Clement, Santos, and Andrade (1999) observed a shelf life of 14 days in minimally processed peach palms in the form of stick, when stored at 10°C. Fonseca et al (2019) evaluated the physicochemical properties of peach palm heartfor minimal processing, and found 8.6° Brix mean soluble solids values and 6.5 pH for median region heart-of-palm, stick type cut, and 7.4° Brix and 6.3 pH for the basal part, chopped type cut. Kalil, Kalil Filho, and Franciscon (2010) found mean soluble solids values of 5.6° Brix and 5.7 pH.…”

The peach palm heart is a hypocaloric gourmet vegetable, rich in fiber and minerals such as potassium, calcium, and magnesium, and it can be incorporated into calorie restriction diets. Minimum processing consists of sanitizing and cutting the products before reaching the consumer, providing convenience to consumption without losing its quality, thus resulting in sufficient shelf life for distribution and marketing. Sanitation, appropriate packaging, and refrigeration are essential practices to extend the shelf life of minimally processed products. Therefore, this study evaluated the quality of peach palm heart produced in Pariquera-Açu – SP, minimally processed in the form of chopped cut and stick, packed in different plastic packages and kept under refrigeration (10 ± 0.5 °C and 85 ± 5% RH) for 9 days. Hearts-of-palm, in chopped cut and stick, packed in PET and PP trays with lids, had their fresh masses and luminosity preserved for 9 days, but there was a failure in the sealing of the lid, which allowed gas exchange with the environment, compromising its quality. The peach palm heart cut in stick, packed in a stretchable PVC coated PE tray, provided protection and efficiency in maintaining quality. The packaging of chopped hearts-of-palm in LDPE packages (0.04 and 0.07 mm), over the storage time, resulted in a high CO2 concentration inside the package, thus, these packages are not recommended.
