Ajustes morfológicos e fisiológicos em plantas jovens de Araucária angustifolia (Bertol.) Kuntze em resposta ao sombreamento

Hoehnea
Este trabalho avaliou a capacidade de plantas de Araucaria angustifolia em ajustar alguns aspectos de sua morfologia e fisiologia a diferentes condições de luz. As plantas foram submetidas a irradiação plena e sombreamento (redução de 90%).

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

In vitro induced cold memory fails to enhance embryogenic cultures development in Araucaria angustifolia [PDF]

Anais da Academia Brasileira de Ciências
This research aimed to study how exposing somatic embryos of Araucaria angustifolia to cold temperatures in vitro could enhance somatic embryogenesis. The somatic embryos were induced from immature zygotic embryos, grown for 120 days, and then subjected ...

Morphometric Relationships as Indicative of Silvicultural Interventions for Brazilian Pine in Southern Brazil

Journal of Agricultural Science, 2018
Silvicultural interventions are necessary to control the competition and to maintain the forest structure. Thus, this work aimed to know the interactions between dendro/morphometric variables to indicate density interventions in Brazilian pine Forest. Dendrometric and morphometric variables were measured from 186 individual trees of this species, which

Sensitivity of brazilian-pine (Araucária angustifolia) embryos to desiccation and temperature

, 2004
O comportamento “recalcitrante” das sementes de Araucaria angustifolia (Bertoloni.) Otto Kuntze (pinheiro-brasileiro) limita a conservação ex-situ dos recursos genéticos dessa importante espécie, em bancos de sementes. A interação entre o conteúdo de água e temperatura sobre a sobrevivência do embrião foi estudada como ponto de partida para o ...
