Morfologia polínica de Caesalpinia echinata Lam. (Leguminosae - Caesalpinioideae) [PDF]
Foram examinados os graos de polen de sete exsicatas de C. echinata. O material polinico foi acetolisado, medido, descrito e fotodigitalizado sob microscopia optica e microscopia eletronica de varredura. Os graos de polen de C. echinata sao, medios a grandes, suboblatos a oblato-esferoidais, âmbito circular, 3-brevicolporados, colpo com margem bem ...

Microsatellite markers for Caesalpinia echinata Lam. (Brazilwood), a tree that named a country [PDF]
Caesalpinia echinata, commonly known as Pau-brasil (Brazilwood), the famous tree that named Brazil is native to the Atlantic forest. Men extensively exploited it ever since discovery and colonial times due to its value as a source of red dye. As a consequence, Brazilwood is a threatened species with populations reduced to small forest fragments.

Microsatellites occur in all plant genomes and provide useful markers for studies of genetic diversity and structure. Chloroplast microsatellites (cpSSRs) are frequently targeted because they are more easily isolated than nuclear microsatellites. Here, we quantified the frequency and uses of cpSSRs based on a literature review of over 400 studies ...

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