“…This was evidenced in the current study by the reduced development of roots and stems when the seedlings were grown in the pure MS medium. These results agree with those obtained by Soares et al (2011) where an original MS medium was unfavorable in the development of seedlings of another native fruit tree of the Cerrado, Acrocomia aculeata. Malavolta (2006) explains that any nutrient in excess causes nutritional imbalances that inhibit seedling development, as observed in the present study.…”

Dipteryx alata Vog. (barueiro) is a native fruit of the Cerrado used in food and medicine. The species has never been domesticated and is currently at risk of extinction. Plant tissue culture is an important tool for the conservation of germplasm and for quick, large-scale propagation of quality seedlings. While, this technique has never been used with barueiro, it could be a valuable tool in the domestication of this species. The objective of this work is to evaluate concentrations of MS medium salts (25, 50, 75 and 100%) supplemented with coconut water (100 mL L -1 ), dwarf banana pulp (60 g L -1 ) or the absence of any supplement in the in vitro establishment of barueiro seeds (Dipteryx alata Vog). The experiment used a completely randomized design (CRD) with a 3x4 factorial scheme (three cultivation media types and four concentrations of MS salts) and three repetitions. The following characteristics were evaluated: germination rate, shoot length , largest root length , stem diameter , number of leaves , chlorophyll A , chlorophyll B , total chlorophyll, and the fresh and dry mass of the seedlings. The coconut water and banana pulp supplements did not improve the in vitro development of the barueiro seedlings and the full concentration of MS salts did not improve the initial development of the seedlings. However, the pure MS medium at a concentration of 25% MS salts was the best option for the in vitro establishment of Dipteyx alata.

“…The predominance of studies evaluating the addition of this liquid endosperm in the culture media are most focused on the in vitro cultivation of orchids. For woody plants using this supplement is still scarce, except for some species, such as Acrocomia aculeata and Hancornia speciosa (SOARES et al, 2011, PINHEIRO et al, 2001.…”

“…Under natural conditions, germination process may take one to two years. In light of this problem, zygotic embryo in vitro cultivation is presented as a potential solution (SOARES et al, 2011;BORCIONI & NEGRELLE, 2012). Dormancy break researches have intensified, and currently, in vitro zygotic embryo culture makes pre-germinated seeds available in market for "macaúba" seedling development and growth.…”

ABSTRACT:The seedling production stage is the key to achieve uniformity in tree breeding stage. This study evaluated "bocaiúva" (Acrocomia aculeata) seedling formation, with pre-germinated seeds in different substrates and protected environments, in the University of Mato Grosso do Sul State, Aquidauana, MS. As substrates, we used 100% cattle manure (M), 100% cassava branches (CB), 100% vermiculite (V), 50% cattle manure + 50% cassava branches, 50 % cattle manure + 50% vermiculite, 50% cassava branches + 50% vermiculite and ⅓ cattle manure + ⅓ cassava branches + ⅓ vermiculite. These substrates were tested in a greenhouse covered with 150 μm low density polyethylene (LDPE) film under thermo-reflective screen with 50% shading under film; black screen with 50% shading on the sides; black monofilament screen with 50% shading set on roof and sides; and aluminized thermo-reflective screen with 50% shading set on roof and sides. The completely randomized experimental design with 5 replications of 5 plants each was adopted. Initially, data were submitted to analysis of substrate individual variance in each growing environment, then performing the waste mean square evaluation and their environment joint analysis for comparison. The best growing environment is the thermo-reflective screen compared to LDPE greenhouse and black screen set. All substrates containing manure are recommended for bocaiúva seedlings formation. The pure cassava branch is not indicated for seedling, even using chemical fertilizer.
