Twenty one alkaloids were isolated from the leaves of Buxus sempervirens var rotundifolia BAILLON. Buxaminol-B, cyclobuxine-D, cyclovirobuxine-D, cycloprotobuxine-C, buxamine-E, buxtauine-M and buxpiine-K were those already known. New alkaloids, the constitution and configuration of which were inferred from physical data and corroborated by interconversion and correlation, were denominated buxithienine-M and cyclobuxophylline-O. The remaining bases were characterized by physico-chemical constant and/or spectral data.

Встановлено, що насадження парку потребують покращення, оскільки деревні насадження одноманітні, значна кількість дерев представлена гіркокаштаном звичайним (Aesculus hippocastanum L.), що уражується мінуючою міллю, інші дерева також ослаблі, трапляється омела. За межами парку простежується велика кількість омели. Мережа доріжок розвинена слабо, малі архітектурні форми представлені у незначній кількості, на території парку присутні аварійні дерева. Розроблено проект реконструкції парку, який охоплює консервацію дупел, санітарне обрізування та рубання дерев і кущів, формування кущового ярусу у структурі насадження, розширення дорожньо-стежкової мережі. Запроектовано створення кількох рокаріїв з використанням листяних і хвойних кущів, різних трав'яних багаторічників, зокрема й цибулькових. Підібрано асортимент для рокаріїв, щоб він виглядав декоративним протягом року. Заплановано кілька групових посадок із хвойних рослин та солітерів – ялини колючої (Рісеа abies (L.) H. Karst.) та сосни звичайної (Pinus sylvestris L.). Запропоновано встановити елементи благоустрою, такі як: садові лавки, альтанка, ліхтарі, урни для сміття. Навколо альтанки запропоновано створення квітників постійного квітування – міксбордерів. В озелененні використано елементи топіарного мистецтва, а саме: композиції зі стриженого самшиту вічнозеленого (Buxus sempervirens L.) у вигляді куль, а також елементи фітопластики. Композиції з куль самшиту вічнозеленого урізноманітнюємо багаторічником – гостою подорожниковидною (Hosta plantaginea (Lam.) Asch.). Рекомендовано частину парку реконструювати за типом регулярного планування, а частину – за типом пейзажного.

Boxwoods (Buxus spp.) are common woody ornamental hedging plants in Europe and North America, typically propagated by cuttings. In October 2011, shoot dieback and defoliation was observed on Buxus sempervirens ‘Suffruticosa’ (dwarf English boxwood) and ‘Green Balloon’ in outdoor, 10-cm pots at a wholesale nursery in Chilliwack, British Columbia. Circular leaf spots with black rings occurred on leaves and black, water-soaked, cankers girdled the stems and petioles. Leaf and stem samples were collected on November 21, 2011, and incubated for 48 h in a moist chamber at room temperature. In addition to Volutella buxi, a Cylindrocladium species producing conidia on white sporodochia was observed on host tissue under the microscope. Leaves with lesions were surface-sterilized in 10% bleach for 30 to 60 s, rinsed in sterile water, and lesions were cut out and plated on PDA and carnation leaf media. The species was identified as Cylindrocladium pseudonaviculatum Crous, J.Z. Groenew. & C.F. Hill 2002 by comparison of conidia and phialide morphology to published descriptions. Conidia were hyaline, one-septate, cylindrical with rounded ends and 38 to 76 μm (mean 51 μm) × 4 to 6 μm on carnation leaf media and 41 to 66 μm (mean 52 μm) × 4 to 6 μm on B. sempervirens ‘Suffruticosa’ leaves, comparable to the reported range of 40 to 75 × 4 to 6 μm (1,2,3,4). Conidia were produced in clusters on terminal, ellipsoid vesicles at the tips of penicillate conidiophores. Vesicles were 10.2 (7.6 to 12.8 μm) at the widest point, consistent with the 6 to 11 μm reported in (2,3) and tapered to a rounded point; stipe extensions were septate and measured an average of 130 μm (107 to 163 μm) in length to the tip of the vesicle, consistent with the 95 to 155 μm reported in (1), 89 to 170 μm reported in (2), and 95 to 165 μm in (3). Chlamydospores were not observed on host tissue but appeared in older PDA cultures as dark brown microsclerotia. DNA was extracted from single-spore colonies on PDA and the internal transcribed spacer (ITS) region of rDNA was amplified with primers ITS1 and ITS4. The ITS sequence (GenBank Accession No. KC291613) was 100% identical to C. buxicola strain CB-KR001 (HM749646.1) and Calonectria pseudonaviculata strain ATCC MYA-4891 (JX174050.1). In early December 2011, box blight was identified on container-grown B. sinica var. insularis × B. sempervirens ‘Green Velvet,’ ‘Green Gem’, and ‘Green Mountain’ and B. sempervirens L. (common or American boxwood). The pathogen was identified by microscopic examination at three wholesale nurseries in the eastern Fraser Valley and one landscape planting. The isolate has been deposited in the Canadian Collection of Fungal Cultures in Ottawa, Canada (DAOM 242242). References: (1) B. Henricot and A. Culham. Mycologia 94:980, 2002. (2) K. L.

During the investigation of fungal microbiome associated with boxwood in the Czech Republic, samples from Buxus sempervirens L. (Buxaceae) plants were collected and used for isolation. Two fungal strains were proposed as a new species Pyrenochaetopsis kuksensis based on morphology as well as phylogenetic analyses of ITS, LSU, rpb2, and tub2 sequence data. Detailed descriptions and phylogenetic relationships of the new taxon are provided.
