“…Among regulators used, GA 3 increased germination. These data reinforce information in literature that this regulator increases the germination percentage of Annona (OLIVEIRA et al, 2010;FERREIRA et al, 2019) including atemoia. Likewise, Braga et al (2010) observed increase in the germination percentage of atemoia cv 'Gefner' seeds from a population in Paraná according to the increase in GA 3 up to concentration of 500 mg L -1 .…”

The objective of this work was to validate the enzymatic activity in Annona x atemoyaseeds submitted to treatments with plant growth regulators belonging to the group of gibberellins and cytokinins for overcoming dormancy during the germination process. Initially, the water acquisition curve was determined, where two points of phase II (72 and 144 hours) were determined to evaluate the activity of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) enzymes in atemoya seeds after the application of two plant growth regulators. Treatments with GA resulted in higher activity of SOD enzyme, which may be favored the higher germination percentage and speed in comparison to control treatment. In cases in which SOD enzyme presented high activity, other enzymes showed the opposite, which indicates the predominantly production of superoxides during this period. The POD enzyme also has activity in seeds treated with gibberellin, which suggests interaction of ROS with GA in the process of dormancy overcoming. Treatments with cytokinin and cytokinin + gibberellin resulted in germination percentage similar to control and no activity pattern of SOD, POD and CAT enzymes that could be correlated with germination metabolism was observed.

Annona senegalensis (Pers.) or Annone from Senegal is a species found in the West African savannah and para-littoral sands. It offers real possibilities of socio-economic use, particularly in the medical, nutritional, ecosystem conservation and poverty alleviation fields. However, this wild species remained not fully exploited despite its potentialities. As a result, there is a need to regenerate this species; therefore, the in vitro propagation from adult material was undertaken. For this purpose, axillary nodes from plant regrowth taken from elderly subjects were aseptically introduced into different media enriched or not with phytohormones. Among the 3 culture media tested, that of Murashige and Skoog (MS, 1962) was the most reactive and made it possible to develop a micropropagation protocol for adult material of A. senegalensis. Thus, the introduction of these explants in media containing cytokinins (BAP and Kinetin) significantly increased the reactivity compared to media without hormones. If the best average numbers of shoots (2.3) and nodes (5.3) are obtained in MS + BAP 2 mg·L −1 , with a reactivity of 91.66%, the addition of 0.1 mg·L −1 NAA gave the best average length (8.25 cm) of vitroplants. An induction time of 3 days into darkness with IBA at 50 mg·L −1 , followed by a transfer to hormone-free expression medium (MS/2) under light, resulted in a rooting rate of 58.33%. After the gradual weaning of the young plants in a mini-greenhouse, under shade for 3 weeks, 50% of the plants survived. This in vitro regeneration protocol can therefore be adopted for the clonal propagation of adult material of A. senegalensis. However, the rooting rate can be improved by trying other hormonal combinations based on auxins or by considering ex-vitro rooting during shade weaning.
