Reference material for botanists, many people residing in practically every Because the publications have become standard These objectives are fulfilled through indoor meetings, outdoor meetings orįields trips, and publications. Today, the society holds as its objectives "to promote interest in botany,Īnd to collect and disseminate information on all phases of plant science." Of the Torrey Botanical Society, in 1870, and was incorporated in 1873. The organization wasįirst named with the appearance of its first publication, The Bulletin Occasionally met in the evening to discuss their findings. Torrey, who were interested in collecting and identifying plants.

Life, including professional and amateur botanists, students, and those who just The Torrey Botanical Society is an organization of people interested in plant florida wood decreased from older wood to younger wood, contrary to what we would expect if Al availability (and hence plant uptake) had increased as a consequence of acid rain. To investigate the third hypothesis, we examined tissue chemistry of both old and young wood. To investigate the second hypothesis, we collected leaves from infected and uninfected trees growing on the same site Al concentrations in leaves from uninfected trees were actually 432 ppm higher than those from infected trees, suggesting that Al toxicity is not likely a factor in the severity of anthracnose infection. canadensis are considered resistant to infection. nuttallii are known to be highly susceptible to infection by dogwood anthracnose, while C. canadensis L., accumulated Al at concentrations an order of magnitude greater than any of the small-bracted species we studied. To investigate the first hypothesis, we collected tissue samples from ten Cornus species from locations across North America for chemical analysis. Finally, we hypothesized that if there was indeed a link between acid rain and anthracnose via Al uptake and toxicity, that younger wood should have higher concentrations of Al than older wood, reflecting increased soil availability of Al. florida would have higher levels of foliar Al than uninfected trees. We also hypothesized that anthracnose-infected C. A wonderful choice at the edge of the woods. They could grow to be over 100 feet tall and 25 feet wide and live up to approximately 300 years. These trees originated from Europe and now resides in the 2/3 of Northeast United States and in East Canada as well. It opens its fragrant yellow flowers in mid-October and may continue blooming into late November or early December. The Norway Spruce may be one of the most iconic trees to exist. Suspecting a possible link between Al and anthracnose, we hypothesized that Al concentrations would be higher in anthracnose-susceptible Cornus species. The common witch hazel ( Hamamelis virginiana) is a 20- to 30-foot low-branched woodland shrub, native to most of the eastern U.S. In a preliminary study, we observed surprisingly high levels of Al in C.
Experimental treatment with simulated acid precipitation has been shown to increase the severity of anthracnose infection. Aluminum is known to be toxic to some plants at low concentrations, and soil availability of Al, and hence plant uptake, may be increased by acid rain. Early observations of this disease were more or less simultaneous with the peak of acid rain in North America. We focus our efforts on your needs and supply you with the best knowledge to enable you to make informed decisions.In both ornamental and forested environments, dogwood anthracnose has caused widespread dieback and decline of Cornus florida L., flowering dogwood, since the late 1970s.
