Última Effect of carbon source on morphology and histodifferentiation of Araucaria angustifolia embryogenic cultures BABT Steiner,Neusa; Vieira,Felipe do Nascimento; Maldonado,Sara; Guerra,Miguel Pedro. The aim of the present work was to establish in vitro conditions for the induction, stabilization and proliferation of embryogenic cultures of A. angustifolia. Pre-cotyledonary staged zygotic embryos inoculated BM medium supplemented with 5 µM 2,4- D, 2 µM BAP and Kin, and 3% maltose or sucrose resulted in 66.7% induction rate. The rate of induction of embryogenic cultures was affected by the carbon source, as well the multiplication and morphology of the embryogenic cultures. Embryogenic cultures maintained in BM medium with maltose presented bipolar morphology. Globular somatic embryos were obtained BM medium with 9% (PEG) and (9%) maltose. These results could establish an in vitro regenerative protocol towards the conservation and improvement of this...

Information on desiccation sensitivity of Euterpe edulis seeds under two drying rates is presented. The sensitivity was studied during the course of germination and normal germination. The water content was evaluated for both seeds and embryos. Results showed the following: (a) For both drying treatments and for both germination and normal germination, desiccation sensitivity values were higher for measurements based on the water content of the embryo than for those of the seed. (b) For both drying treatments, desiccation sensitivity were higher for normal germination than for germination based on both the embryo and seed water contents. (c) Under the slow drying treatment and for measurements based on the seed water content, critical water content was...

Comparative studies on fatty acid and protein composition of the endosperm and embryo of palmito (Euterpe edulis Martius) were conducted using gas-liquid chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. On a dry weight basis, the embryo contained extremely lower amounts of lipids and proteins than did the endosperm, which was associated with the scarce lipid and protein bodies previously reported in axis and cotyledon. The fatty acid composition also exhibited differences between both tissues: (I) the fatty acid diversity was greater in embryo than in endosperm; (II) embryo and endosperm contained predominantly linoleic, palmitic, oleic and stearic acids even though the relative values were different for each tissue. As... Tipo: Info:eu-repo/semantics/article Palavras-chave: Palm seeds; Arecaceae; Fatty acids; Recalcitrant behavior; Storage susceptibility.
