Stimulation effect of synthetic plant growth regulator (GA3 and BAP) on young cinchona plant (Cinchona ledgeriana) grown in lowland

Bioproduction of Cinchona alkaloids by the endophytic fungus Diaporthe sp. associated with Cinchona ledgeriana.

We report that an endophytic filamentous fungus species of the genus Diaporthe isolated from Cinchona ledgeriana (Rubiaceae) produces Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine) upon cultivation in a synthetic liquid medium. This study provides evidence that Cinchona alkaloids are produced not only in Cinchona plant cells, but also in the endophytic microbe cells, and ...

Influence of High, Medium, and Low Soil Moisture on Growth and Alkaloid Content of Cinchona ledgeriana.

Introduction ,Soil moisture in Cinchona growing regions may fluctuate greatly with seasonal changes in rainfall; prolonged droughts are experienced almost annually. On the other hand, during the peak of the rainy season the same soils may remain at or near saturation for extended periods. For example, at the Toro Negro National Forest in Puerto Rico, where Cinchona is being grown experimentally...

The Effect of Three Factorial Levels of Nitrogen and Phosphorus on the Growth and Composition of Cinchona Ledgeriana.

Most of the cultural trials and experiments with cinchona prior to 1900 were recorded as observations. AWith the possible exception of the work by COWGILL (1) the published information with reference to the effects of fertilizer applications onl growth and alkaloid content of cinchona deal mainly with established trees (3, 4, 8, 9, 11). Although it is generally conceded that the first few month...
