In vitro propagation of jamelão (syzygiumcumini (l.) skeels)

Syzygiumcumini (L.) Skeels is a plant species belonging to the Myrtaceae family, popularly known as jamelão, jamun, or Indian jamelão, widely used in medicine because of its hypoglycemic effects. In vitro cultivation is an alternative to seedling production and conservation of this important genetic resource, highlighting the micropropagation, which allows to obtain high quality plants, with identical genetic characteristics and in a short time. Thus, the study aimed to establish a seed germination system and in vitro multiplication of the jamelão (explants of nodal segments) with different treatments of Stimulate® (biostimulant), and 6-benzylaminopurin and 1-naphthaleneacetic acid, respectively. S.cumini seeds treated with 20.0 mL kg-1 of biostimulant resulted in higher rates of in vitro germination compared with other concentrations. On the other hand, a combination of 2.0 mg L-1 of 6-benzylaminopurin and 0.5 mg L-1 of 1-naphthaleneacetic acid favored the increase in the number of leaves, height (cm), and fresh mass (g) of the seedlings, resulting in the most suitable treatment for micropropagation of nodal segments of S.cumini. With the results obtained in this work, it can be concluded that the protocol used was efficient for the establishment of a micropropagation system of jamelão.
