New Orange Resources Published at Pomology org

Pomology is the science and technology of cultivating and producing fruits and within this discipline, Pomology.org provides a wide range of resources related to temperate, subtropical and tropical fruits.

The Sweet Orange (Citrus sinensis, Rutaceae) is an ancient hybrid between pomelo (C. maxima) and tangerine (C. reticulata). Orange fruits are widely grown in warm climates worldwide, and commonly eaten fresh, or squeezed for their juice. Orange trees are widely cultivated in tropical and subtropical climates.

The Orange section is part of the Fruit Crop Category of Pomology.org and currently contains 59 resources. One of the most popular entries is an article on “Partial Purification of a Growth Factor from Orange Juice Which Affects Citrus Tissue Culture and Its Replacement by Citric Acid” which was published in the science journal “Plant Physiology” in 1975.

The authors conclude that citric acid as a natural component of citrus juice is responsible for the growth-promoting activity of orange juice. The growth-promoting activity of juice involves both cell division and cell enlargement. Another popular article from the same journal covers “Endogenous Abscisic Acid in Relation to Bud Growth in Alternate Bearing ‘Valencia’ Orange”.
Other resources provide information on cultivation of oranges including a page on sweet oranges and their hybrids provided by the University of California, College of Natural and Agricultural Sciences’ Citrus Variety Collection. Purdue University’s Center for New Crops and Plant Products publishes a page on Orange which includes a range of topics on the crop such as origin and distribution, varieties, climate, soil, propagation, culture, harvesting, yield, pests and diseases, food uses and value, and toxicity.

The section also provides information on Calamondin, the miniature orange which is a native citrus plant in the Philippines and China. The juice of its fruit is primarily used like lime or lemon juice for making acid beverages.

Pomology.org was launched in 1996 and has emerged as a comprehensive aggregator of websites and science references in the applied life science Pomology. The site is now under new management and has just been republished.

Users who wish to submit their own or their company’s website for inclusion in Pomology.org are welcome to submit their listing through the site. Furthermore, the site maintains a number of RSS feeds which enable users to subscribe to their most favorite topics within the site.
