| Babassu is a highly productive oil plant that is propagated from seed. Therefore, tissue culture techniques are of great importance because propagation is accelerated. The objective of this study was to evaluate the effect of growth regulators, NAA, BAP, and KIN, on in vitro germination and on the growth of babassu zygotic embryos. Three trials were conducted. For trial (I), the interaction between NAA (0, 1, and 2 µM) and KIN (0, 1, and 2 µM) were studied; for trial (II), the interactions among NAA (0, 1, and 2 µM), KIN (0, 1, and 2 µM), and BAP (1 µM) were studied; and for trial (III), the interactions among NAA (0, 1, and 2 µM), KIN (0, 1, and 2 µM), and BAP (2 µM) were studied. At 30, 60, 90, and 120 days of culture, we assessed average seedling... |

| Micropropagation is an important tool for the multiplication of native Cerrado species. However, understanding the responses of these species under in vitro culture conditions is still incomplete. Thus, the present study aimed to analyze the growth, anatomical behavior and physiology of Pouteria gardneriana cultivated in vitro under photoautotrophic conditions. Nodal segments were cultured at photosynthetic photon flux densities (PPFD) of 75, 100 and 150 µmol m-2 s-1 in culture medium MS 50% solidified with 3.5 g L-1 of agar and 2.0 g L-1 of activated charcoal, in the absence and presence of 30 g L-1 of sucrose. After 60 days of in vitro culture, the P. gardneriana plantlets only regenerated when sucrose was present in the culture medium. Higher fresh and... |
