Foundation Arboretum Wespelaar Year Report 2019
Foundation Arboretum Wespelaar Year Report 2019 2019 started with an early spring: by mid-March the early magnolias were in full flower. Temperatures kept rising and the heat record was broken in July, making the summer of 2019 one to be recorded in history books. Luckily, small rain showers and increased irrigation capacities ensured that we lost very few plants. In March 2019, the construction of the Artois Pavilion started in the Artois Meadow, at the end of two important vistas. The design is inspired by the old pavilion along the canal in the Park of Wespelaar. In the new Arboretum de Marche, a total of 189 trees have been planted in the past two years. In collaboration with Natagora, five ponds were created and a 5ha plot was sown with wild seed to create a meadow of native grasses and flowers. The building permit for the visitors centre and technical facilities was obtained. 2019 was a very active year for both Arboretum Wespelaar and Arboretum de Marche, as is described in more detail in this Year Report. Arboretum Wespelaar – Year Report 2019 1 THE COLLECTIONS ‘Patty’ can be planted in the Arboretum in due time. The living collection of woody plants in the Arboretum currently (as of 30 January 2019) Once again, our winter was not worth contains 5,116 specimens representing 2,340 mentioning and by mid-March we could have different taxa (versus 16,376 specimens and opened the Arboretum for our visitors because 4,955 taxa on the whole of the estate). These the early magnolias were already in full flower! numbers include the 629 new accessions on On March 11th however, we had a serious the estate during 2019 of which 108 (or 17%) storm with accompanying damage and much are of documented wild origin.

Grows vertically with a straight main trunk. The winter buds are a remarkable brownish-red colour and glossy. In the spring the young leaves emerge almost white. Once they are fully grown only the underside remains a remarkable light grey. The leaves are rough and slightly lobed. No other ornamental apple tree has such exceptional autumnal colours as this. With its many shades, from purple and copper through orange to yellow, the tree is a real eye-catcher in the autumn. The (fragrant) flowers and the fruits are much less spectacular than those of the other ornamental apple trees.

Japanese Apple Rust Gymnosporangium Yamadae Belongs to the Pucciniales, an Order That Includes Rust Fungi That Cause Diseases on Plants
U.S. Department of Agriculture, Agricultural Research Service Systematic Mycology and Microbiology Laboratory - Invasive Fungi Fact Sheets Japanese apple rust Gymnosporangium yamadae belongs to the Pucciniales, an order that includes rust fungi that cause diseases on plants. Gymnosporangium yamadae has been limited in distribution to Asia (China, Japan and Korea) where it can be a serious pathogen of cultivated apples, especially if the host of the telial state, Juniperus spp., occurs in close proximity. This fungus was recently reported from the United States (DE, PA) in its aecial state on the ornamental tree, Malus toringo (Yun et al. 2009). Gymnosporangium yamadae Miyabe ex G. Yamada 1904 Aecia on Malus, foliicolous, then hypophyllous, also less commonly caulicolous, fructicolous; initially developing in a whitish leaf spot that becomes rose red with a distinct margin. Peridium cornute to tubular, 3-7(-8) mm high, retaining this shape at maturity but with lacerate sides that often form a reticulate pattern, apex typically closed to occasionally dehiscent, yellow-brown to brown; peridial cells long-narrow rhomboid to linear-rhomboid, 59-115 µm long, pale yellow, appearing verrucose with long papillae to tuberculate, outer walls smooth, inner and side walls sparsely echinulate. Aeciospores globoid, 16-26 × 18-27 µm, walls dark yellow, 1.0-2.5 µm thick, rarely up to 3.5 µm thick, sparsely echinulate, 4-7 pores scattered on surface. Telia on Juniperus, caulicolous, rarely foliicolous, produced on globoid swellings or small galls, telial horns cylindric-acuminate, 1-3 mm diam, 5-8 mm high or more, orange, gelatinouse. Teliospores two-celled, oblong, ellipsoid or obovoid, 15-28 x 32-56 µm, walls 0.8-2.0 µm thick, yellow or orange, with two pores near septum and one pore toward apex in upper cell, frequently with an obtuse, hyaline papilla at apex.

The Best Street Trees
I 83 THE BEST STREET TREES Considering all factors affecting street trees, it takes a strong, adaptable plant to endure today’s environmental stresses and survive in reasonably good condition. The following trees have proven durable and functional in appearance, structural strength, pest resistance, adaptability to inhos- pitable soils, and resistance to storm and mechanical damage. They also require minimal pruning to keep them visually and structurally sound. Barring unforeseen circumstances, they can be expected to live thirty to forty years or more. Most important, they are commercially available in landscape size and generally at reasonable prices. Although these trees represent our choice of the "best," they are not infallible. A plant that performs admirably in one area of the country may not duplicate that effort in another region. Honeylocust has suffered in recent years in the Midwest from canker, webworm, gall, and mites, while in New England these problems do not appear prevalent. The selec- tion of trees for city planting should, therefore, be based on a thorough knowledge of all factors which contribute to their successful establishment. :. ________ ., C.i Effective use of Pyrus calleryana ’Bradford’ for screening a parking lot. 84 I Acer buergeranum HEIGHT: 20-35 feet SPREAD: 15-25 feet HABIT: oval-rounded to rounded ZONE: 5, perhaps best in 6 ENVIRONMENT: full sun to light shade; well-drained soil; withstands drought and heat 85 A small tree with lustrous, dark green foliage that turns yellow and red in fall, Acer buergeranum exhibits good pest and drought tolerance.

But did you know they also help reduce stormwater runoff, filter pollutants, add Toxygen to the air we breathe, and decrease glare from roadways? For example, Lake Oswego’s street tree canopy (representing 13% of the total 44% citywide tree canopy cover) intercepts about 50 Olympic-size swimming pools worth of rainfall annually based on data compiled in the City’s 2009 State of the Urban Forest Report. Conserving existing trees and planting new trees help reduce the size and cost of hard infrastructure that is otherwise necessary for stormwater management. 3 Selecting A Tree Before selecting a tree to plant, a number of factors should be considered to ensure that an optimum species is chosen based on the site conditions of the available growing space. Choosing the right tree for the right place is a decision that will have an impact on the neighborhood for decades to come. Answering these questions can help you select the most suitable and desirable tree species for your site: 1. What is the size of the available growing space? 2.

Dihydrochalcones in Malus Mill. Germplasm and Hybrid
DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Benjamin Leo Gutierrez December 2017 © 2017 Benjamin Leo Gutierrez DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS Benjamin Leo Gutierrez, Ph.D. Cornell University 2017 Dihydrochalcones are abundant in Malus Mill. species, including the cultivated apple (M. ×domestica Borkh.). Phloridzin, the primary dihydrochalcone in Malus species, has beneficial nutritional qualities, including antioxidant, anti-cancer, and anti-diabetic properties. As such, phloridzin could be a target for improvement of nutritional quality in new apple cultivars. In addition to phloridzin, a few rare Malus species produce trilobatin or sieboldin in place of phloridzin and hybridization can lead to combinations of phloridzin, trilobatin, or sieboldin in interspecific apple progenies. Trilobatin and sieboldin also have unique chemical properties that make them desirable targets for apple breeding, including high antioxidant activity, anti- inflammatory, anti-diabetic properties, and a high sweetness intensity. We studied the variation of phloridzin, sieboldin, and trilobatin content in leaves of 377 accessions from the USDA National Plant Germplasm System (NPGS) Malus collection in Geneva, NY over three seasons and identified valuable genetic resources for breeding and researching dihydrochalcones. From these resources, five apple hybrid populations were developed to determine the genetic basis of dihydrochalcone variation. Phloridzin, sieboldin, and trilobatin appear to follow segregation patterns for three independent genes and significant trait-marker associations were identified using genetic data from genotyping-by-sequencing. Dihydrochalcones are at much lower quantities in mature apple fruit compared with vegetative tissues.

Evaluation of the Crabapple (Malus) Collection and Assessment of the Crabapple Slope Abstract This project began in response to space on the slope for more crabapple trees and a need to evaluate the current crabapple collection. As such, this project examined the collection as a whole with special attention to the slope. The Morris Arboretum had 48 crabapple trees as of 2018. The vast majority were planted in two locations: the slope by the rose garden and on the farm between the community garden and the executive director’s residence. The initial examination of the collection showed only two native crabapple specimens (Malus coronaria) both with a provenance of Maryland. Propagation of a tree with more local provenance was done to improve and expand the Malus collection. The four parts to this project included development and implementation of evaluation criteria, soil testing of the slope, recommendations of crabapple cultivars to fill empty spaces on the slope, and propagation of a native crabapple (Malus coronaria) with local provenance Disciplines Horticulture Comments An independent study project report by The Charles C.
