    Moore in America: Monumental Sculpture at The New York Botanical Garden May 24 – November 2, 2008 Backgrounder: The New York Botanical Garden’s Legacy of Natural and Designed Landscapes The New York Botanical Garden, a 250-acre site that has been designated a National Historic Landmark, offers a wealth of beautiful landscapes, including a hardwood Forest, ponds, lakes, streams, rolling hills with dramatic rock outcroppings carved by glaciers, and New York City’s only freshwater river, which runs through the heart of the Forest in a magnificent rock gorge. These picturesque natural features have been further enhanced by more than a century of artful plantings, gardens, and landscapes designed by the nation’s leading landscape architects and garden designers. As a result of both its natural and human legacies, the Botanical Garden today offers an exceptional setting for outdoor sculpture. Scenic beauty and stunning natural features Following the New York State Governor’s approval on April 28, 1891, of The New York Botanical Garden Act of Incorporation, a site needed to be selected for the location of this new educational and scientific institution. Selection turned to an undeveloped park in the central Bronx. In 1887, a published description of this area notes, “it would be difficult to do justice to the exquisite loveliness of this tract without seeming to exaggerate…gigantic trees, centuries old, crown these summits, while great moss and ivy-covered rocks project here and there at different heights above the surface of the water, increasing the wildness of the science.” An 1893 newspaper account describes the romantic vistas of an old stone house, snuff mill, and other artifacts of previous land use, while surrounded with “almost every tree known to the American forest in the Northern clime.” The underlying bedrock, dark gray Fordham gneiss, shapes many rock outcrops, rolling hills, and steep slopes, ranging from 20 to 180 feet above sea level.

The development and maturation processes of these fruits follows a series of molecular and physiological events that leads to modifications in size, color, texture, flavor, and aroma. Although the ripening process of climacteric fruits has been well-documented, the signals triggering in non-climacteric fruit remains poorly understood. However, the involvement of phytohormones in this process has been demonstrated.

  • Agriculture and the Future of Food: the Role of Botanic Gardens Introduction by Ari Novy, Executive Director, U.S
    Agriculture and the Future of Food: The Role of Botanic Gardens Introduction by Ari Novy, Executive Director, U.S. Botanic Garden Ellen Bergfeld, CEO, American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America The more than 320 million Americans alive today depend on plants for our food, clothing, shelter, medicine, and other critical resources. Plants are vital in today’s world just as they were in the lives of the founders of this great nation. Modern agriculture is the cornerstone of human survival and has played extremely important roles in economics, power dynamics, land use, and cultures worldwide. Interpreting the story of agriculture and showcasing its techniques and the crops upon which human life is sustained are critical aspects of teaching people about the usefulness of plants to the wellbeing of humankind. Botanical gardens are ideally situated to bring the fascinating story of American agriculture to the public — a critical need given the lack of exposure to agricultural environments for most Americans today and the great challenges that lie ahead in successfully feeding our growing populations. Based on a meeting of the nation’s leading agricultural and botanical educators organized by the U.S. Botanic Garden, American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, this document lays out a series of educational narratives that could be utilized by the U.S. Botanic Garden, and other institutions, to connect plants and people through presentation

  • Effect of Preharvest Fruit Temperature on Ripening, Sugars, and Watercore Occurrence in Apples
    J. AMER. SOC. HORT. SCI. 119(6):1208–1214. 1994. Effect of Preharvest Fruit Temperature on Ripening, Sugars, and Watercore Occurrence in Apples Hisashi Yamada, Hirokazu Ohmura, Chizuru Arai, and Makoto Terui Laboratory of Horticultural Science, Faculty of Agriculture, Niigata University, Ikarashi 2-8050, Niigata 950-21, Japan Additional index words. Malus domestica, ‘Himekami’, ‘Fuji’, sorbitol, maturity Abstract. The influence of controlling temperature during apple (Malus domestica Borkh.) maturation on sugars, fruit maturity, and watercore occurrence was investigated in watercore-susceptible ‘Himekami’ and ‘Fuji’ apples. The incidence of watercore at 13/5 and 23/15C was greater than at 33/25C or ambient temperatures in ‘Himekami’ apples in 1991 and was greater at 18/10C than at other temperatures in ‘Fuji’ apples in 1990. In 1992, the extent of watercore increased as fruit temperature decreased from 28 to 14C and 23 to 9C in ‘Himekami’ and ‘Fuji’ apples, respectively. Watercore occurrence affected by fruit temperature was not related to fruit maturity, as judged by ethylene evolution. The effect of fruit temperature on sorbitol was relatively small compared with that on other sugars, and no relationship was found between watercore development and sugars. These results suggest that fruit temperature affects watercore expression independently of fruit maturity or sorbitol metabolism in the fruit in watercore-susceptible apple cultivars. Watercore is a physiological disorder of apple that develops peratures. These temperature effects on sugar composition were while fruit are on the tree. Apple cultivars differ in watercore verified experimentally by adjusting fruit temperature in the field expression and, by using grafting combinations, Kollas (1968) (Yamada et al., 1988).
