“…Gas exchange in micropropagation has been shown to be an effective means of improving plantlet quality. Silveira et al (2019) observed that natural ventilation resulted in increases of 448.53% in the number of leaves, 85.64% in chlorophyll a content and 74.90% in chlorophyll b content in micropropagated Eugenia dysenterica DC. (Myrthaceae).…”

The objective of this study was to evaluate the effect of the use of different natural ventilation systems on the growth and accumulation of total phenolic compounds in Aloysia gratissima. Nodal and apical segments with 1 pair of leaves were inoculated in flasks containing ½ MS culture medium without sucrose and supplemented with 0.1 mg L-1 indole-butyric acid. The cultivation systems included a conventional system (NMS) and alternative membrane systems with 1 (AMS1), 2 (AMS2) and 4 (AMS4) low-cost membranes. After 30 days, the in vitro growth, leaf area, dry weight and accumulation of phenolic compounds were evaluated. Plantlets from apical segments showed superior results in all variables analyzed. The use of the NMS compromised plantlet growth. However, improved results were obtained with the use of porous membranes, with the best growth observed in AMS4. The leaf area of plantlets originating from apical segments was 3.03 times greater than that of plantlets from nodal segments. Plantlets in the NMS had the lowest values of leaf area, root length, number of leaves and dry weight. However, the use of membranes allowed higher growth. The AMS4 treatment increased the leaf dry weight accumulation by 6.13-fold compared to that obtained with the NMS treatment. The accumulation of total phenolic compounds increased with the use of greater numbers of porous membranes. The use of apical segments and lids with 4 porous membranes is recommended for micropropagation of the species. The use of an alternative membrane system positively influences the accumulation of total phenolic compounds.

Myrteae is the most species-rich tribe in the Myrtaceae family, represented by a range of socioeconomically and ecologically significant species. Many of these species, including commercially relevant ones, have become increasingly threatened in the wild, and now require conservation actions. Tissue culture presents an appropriate in vitro tool to facilitate medium-term and long-term wild germplasm conservation, as well as for commercial propagation to maintain desirable traits of commercial cultivars. So far, tissue culture has not been extensively achieved for Myrteae. Here, tissue culture for Eugenia, one of the most species-rich genera in Myrteae, is reviewed, giving directions for other related Myrteae. This review also focuses on ex situ conservation of Australian Myrteae, including using seed banking and field banking. Despite some progress, challenges to conserve these species remain, mostly due to the increasing threats in the wild and limited research. Research into in vitro methods (tissue culture and cryopreservation) is paramount given that at least some of the species are ‘non-orthodox’. There is an urgent need to develop long-term in vitro conservation for capturing the remaining germplasm of threatened Myrteae.
