The Germination Characteristics of Tithonia rotundifolia

Annals of Botany, 1990
The achenes of the plant Tithonia rotundifolia show an embryo dormancy, requiring a 3-month period of after-ripening to stimulate germination. Mechanical scarification did not enhance imbibition of the achenes, indicating that the thick bi-layered achene wall does not impede water uptake.

Sesquiterpenoids and diterpenoids from Tithonia longiradiata

Phytochemistry, 1992
Abstract Tithonia longiradiata yielded several known compounds and the new heliangolides 3-acetyl-15-hydroxy-2′,3′-dihydroleptocarpin and 15-hydroxy-2′,3′-dihydroleptocarpin. The structures were established by spectroscopic studies, chemical transformations and confirmed by a chemical correlation with dihydrohelianginol of known stereochemistry.
