The exotic invasive candle bush Senna alata (L.) Roxb. in Baja California Peninsula, México, a new threat for relictual oasis

Impact of auto exhaust emission on seed germination and seedling growth behavior of Senna alata (L.) Roxb.- (Candle bush) an important medicinal and ornamental flowering tree

Sennosides A and B production by hairy roots of Senna alata (L.) Roxb.

Hairy roots of Senna alata transformed with Agrobacterium rhizogenes, strain ATCC 15834 were induced and grown in half-strength Murashige and Skoog (MS) medium. Effects of sucrose contents and hormones on the growth and sennosides A, B production were investigated. Hairy roots cultured on hormone-free half-strength MS medium containing 5% sucrose under dark condition mostly stimulated the growt...

Stimulation of Growth and Development of Celosia argentea L. by Crude Extracts of Senna alata (L.) Roxb

The effects of different concentrations of Senna alata crude water extracts on the germination, growth and flowering of Celosia argentea were studied. All concentrations of this extract induced a consistent decrease in absolute percentage and rate of germination, and inhibited radical elongation in Celosia argentea. Earliness in flowering and overall increase in height was obtained from seedlin...

Evolution of the margin of the Gulf of California near Loreto, Baja California Peninsula, Mexico

The Gulf of California is a prime example of a young oblique-divergent plate boundary. This type of plate boundary is much less well understood than classic rifts and passive margins in divergent plate settings. A complexity in the Gulf of California is that the modern oblique rifting was preceded by a stage of orthogonal rifting. We have used extensive mapping as well as stratigraphic, geomorp...

California sea lions (Zalophus californianus californianus) have lower chlorinated hydrocarbon contents in northern Baja California, México, than in California, USA.

Chlorinated hydrocarbons (CHs) were determined in blubber samples of 18 California sea lions (Zalophus californianus californianus) that stranded dead along Todos Santos Bay, Ensenada, Baja California, México, January 2000-November 2001. Summation operatorDDTs were the dominant group (geometric mean 3.8 microg/g lipid weight), followed by polychlorinated biphenyls ( summation operatorPCBs, 2.96...
