In vitro bulbing for the propagation of Traubia modesta (Amaryllidaceae), a threatened plant endemic to Chile Ciencia e Investigación Agraria
Paredes,Kelly; Delaveau,Catherine; Carrasco,Pedro; Baeza,Carlos; Mora,Freddy; Uribe,Matilde E.
K. Paredes, C. Delaveau, P. Carrasco, C. Baeza, Freddy Mora, and M.E. Uribe. 2014. In vitro bulbing for the propagation of Traubia modesta (Amaryllidaceae), a threatened plant endemic to Chile. Cien. Inv. Agr. 41(2): 207-214. Critically endangered, Traubia modesta is endemic to Chile and belongs to the family Amaryllidaceae. In this research, a propagation protocol was developed for the in vitro cultivation of vegetative organs for this species. The twin scale explants were cultured in a Murashige and Skoog (MS) medium, supplemented with the growth regulators naphthaleneacetic acid (NAA) and 6-benzylaminopurine (BAP) in different concentrations. Plant preservative mixture (PPM) and polyvinyl pyrrolidone (PVP) were used as a biocide and an antioxidant,...

Pollination and breeding system in Adesmia bijuga Phil. (Fabaceae), a critically endangered species in Central Chile Gayana Botánica
GÓMEZ P,PERSY; LILLO,DIANA; GONZÁLEZ,ALEJANDRA V.
Adesmia bijuga Phil. is an endemic shrub in central Chile, classified as a critically endangered species of plant. After more than 100 years since its original description by R. A. Philippi (1884), the species was rediscovered exclusively in two locations of the Maule Region. One of them, Fundo San Pedro-Las Cañas, is close to extinction with a low number of shrubs, occurring in a disturbed habitat due to plantations of Pinus radiata. This study examined the pollination biology and breeding system of A. bijuga in order to explain their small number of shrubs. We estimated composition of pollinator species attracted to flowers and visitation rates. In order to describe its breeding system in A. bijuga we used manipulated treatments to estimate autonomous...
