Joseph Gaertner
Joseph Gaertner (12 March 1732 – 14 July 1791) was a German botanist, best known for his work on seeds, ''De Fructibus et Seminibus Plantarum'' (1788-1792). Biography He was born in Calw, and studied in Göttingen under Albrecht von Haller. He was primarily a naturalist, but also worked at physics and zoology. He travelled extensively to visit other naturalists. He was professor of anatomy in Tübingen in 1760, and was appointed professor of botany at St Petersburg in 1768, but returned to Calw in 1770. Gaertner made back cross to convert one species into another. Back cross increases nuclear gene frequency His observations were: 1. Dominance of traits 2. Equal contribution of male and female to the progeny 3. No variation in F1 (first generation of descendants) 4. Large variation in F2 (second generation of descendants) including parental and intermediate types 5. Some of F2 plants had entirely new traits but he was unable to give possible explanation for obs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Connaraceae
Connaraceae is a pan-tropical plant family of 19 genera and more than 180 species of largely evergreen trees, woody shrubs and climbers. The family was first described by Robert Brown in 1816 and the name has been conserved. Distribution Connaraceae is a tropical family, the most important genera of which, ''Connarus'' (approximately 80 species) and ''Rourea'' (40-70 species) have a pan-tropical distribution. Their habitat is generally lowland tropical rain forest and savanna. Description Connaraceae are typically evergreen trees, shrubs or climbers. ''Connarus'' is represented by species in all three lifeforms, while ''Rourea'' species are climbers. Their leaves are pinnate, trifoliate or rarely entire, alternate, without stipules and with a pulvinus at the base of the petiole. ''Connarus guianensis'' is economically important for its decorative wood, zebra wood.
