Vegetative responses to temperature and photoperiod in saplings of brazilwood (Caesalpinia echinata Lam., Leguminosae)

Abstract: Caesalpinia echinata Lam. (brazilwood) is an endangered tree species occurring along the eastern coast of Brazil from latitudes 5°56´S to 22°56´S. With such a range of distribution it is expected that temperature and daylength may affect plant development, which was examined in this study. One-and five-year-old saplings were grown under controlled photoperiods of 8 h, 12 h and 20 h, and in a greenhouse under natural light during 16 months. In another experiment, oneyear-old saplings were cultivated for six mon… Show more

“…In fact, higher RMR and smaller LMR were verified in brazilwood plants under 0 and 50% shade (Table 2), thus supporting this premise. However, one should take into account that most luminous radiation is associated with higher temperatures and which together may affect the growth in intermediate species as observed by Rondon et al (2006) in brazilwood of plants grown in elevated temperatures.…”

“…Com isso, a adição de nutrientes para as plantas através da adubação do solo pode ter efeito no crescimento da parte área (altura e diâmetro) no sistema radicular e na tolerância a pragas e doenças (HOPE et al, 2004). Apesar do alto valor econômico e da importância histórica do Paubrasilia echinata ainda é pouco conhecido seu desenvolvimento e crescimento no campo, as pesquisas realizadas com a espécie são mais concentradas na fisiologia de sementes e efeitos da luminosidade no crescimento inicial e no efeito da adubação em mudas (AGUIAR et al, 2005;GARCIA et al, 2006;RONDON et al, 2006;MELLO;BARBEDO, 2007;MENGARDA et al, 2009;CANAL, 2010) (cm) pH (H2O)…”
