O objetivo deste trabalho foi definir o tipo de substrato e a temperatura mais adequada à germinação sementes Dalbergia nigra (Vell.) Fr. All. Ex Benth (jacarandá-da-bahia), conhecer morfologia seu desenvolvimento pós-seminal caracterizar as plântulas normais, os padrões anormalidade. As foram semeadas nos substratos sobre papel, rolo papel vermiculita, nas temperaturas constantes 20, 25, 30 35°C alternadas 20-30°C 20-35°C. delineamento estatístico empregado inteiramente casualizado (6x3),...
Abstract We evaluated the effect of temperature regimes (six constant and four alternating temperatures), light qualities (five red : far ratios) water potentials (ΨW; seven NaCl polyethylene glycol 6000 [PEG] solutions) on percentage germination rate, as well post‐seminal development morphology, that allow Pilosocereus arrabidae seeds to germinate in a hot semiarid climate south‐eastern Brazilian coast. The results showed germinated similarly between temperatures, with an optimal at 25/20°C...
