Although Rhododendron is the most important host of Phytophthora ramorum in Europe, there is little scientific information about the susceptibility levels of different Rhododendron species and cultivars. Increasing this knowledge would help nurseries in the management of the disease and could be used by plant protection services to target their inspections. In this study a total of 80 Rhododend...

Kebun Raya Biologi Wamena (KRBW) merupakan satu - satunya kawasan konservasi ex-situ di ekoregion Papua yang terletak Kabupaten Jayawijaya. Sebagai kebun koleksi dataran tinggi, maka dipilihlah marga Rhododendron sebagai salah dari beberapa tumbuhan. Hingga saat ini, KRBW telah mengoleksi 8 jenis Rhododendron, artinya hanya 7,07% total tersebar Papua. Dari ini ditemukan 3 warna bunga yaitu kuni...

A new mycorrhizal fungal strain was isolated from hair roots of Rhododendron fortunei Lindl. grown in Huading Forest Park, Zhejiang Province, China. Morphological characterization and internal transcribed spacer rDNA analysis suggested that it belongs to Oidiodendron maius Barron, and we designated it as strain Om19. Methods for culturing Om19 were established, and the ability of Om19 to form m...

Pollinator and/or mate scarcity affects pollen transfer, with important ecological and evolutionary consequences for plant reproduction. However, the way in which the pollen loads transported by pollinators and deposited on stigmas are affected by pollination context has been little studied. We investigated the impacts of plant mate and visiting insect availabilities on pollen transport and rec...

Elevation gradients are frequently used as space-for-time substitutions to infer species' trait responses to climate change. However, studies rarely investigate whether trait responses to elevation are widespread or population-specific within a species, and the relative genetic and plastic contributions to such trait responses may not be well understood. Here, we examine plant trait variation i...

Two new species, Exobasidium rhododendri-nivalis on Rhododendron nivale and E. pyroloides on Gaultheria pyroloides, are reported. They were collected from Yunnan and Sichuan Provinces. Exobasidium rhododendri-nivalis causes small galls on leaves, stems and shoots, while E. pyroloides causes red leaf spots. Exobasidium cylindrosporum on Rhododendron sp., collected from Jiangxi Province, is repor...
