many powdery mildew fungi occur as anamorphic state on different host plants in guilan province, iran. the species have usually been identified as oidium spp. in order to identify teleomorphic species using anamorphic characteristics and host range, several infected plant specimens were collected from around guilan province during 2004-2011. based upon  the  results of the study 25 species were...

Development, survivorship, longevity, reproduction, and life table parameters of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), were examined in the laboratory using three host plants, sunflower (Helianthus annuus L.), Chrysanthemum morifolium L., and euonymus (Euonymus japonica Thurb.). Females deposited similar-sized egg masses on all three plants. Hatching was highest with...

PREMISE OF THE STUDY Begonia fimbristipula (Begoniaceae) is a medicinal herb distributed in the Chinese provinces of Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi, and Zhejiang, and it is on the verge of extinction due to habitat destruction and deterioration of its ecosystem. Here we developed a set of highly polymorphic microsatellite markers for population genetic and conservation studi...

The short-day plants Begonia cheimantha, Chrysanthemum morifolium (one pot and one cut cultivar), Euphorbia pulcherrima (poinsettia) and Kalanchoe blossfeldiana were grown at vapour pressure de®cits (VPDs) of 155, 420 and 660 Pa (corresponding to 93, 81 and 70% relative air humidity, respectively). The lowest VPD delayed time to ̄owering by three to four days in pot and cut chrysanthemum but di...

Paclobutrazol (PBZ) is one of the most important triazole compounds. This compound increases plant tolerance to environmental stresses. A study aimed to investigate the effects of PBZ on morphological and biochemical traits of euonymus (Euonymus japonicas) exposed to NaCl stress. Plants were treated with three levels of PBZ (0, 500 and 1000 mg L-1) and four levels of NaCl (0...

Since 2016, KIB (Kunming Institute of Botany) and CPC (Centre for Plant Conservation of Vietnam) have conducted several surveys in the transboundary karst regions in Northern Vietnam and Southern China and seven new species in the genus Begonia Linn. (Begoniaceae) are firstly described. Amongst them, two species, Begonia albopunctata Y.M. Shui, W.H. Chen & H.Q. Nguyen and B. erectocarpa H.Q. Ng...

The 29 Nepalese species of the pantropical genus Begonia largely belong to 2 sections, Begonia sect. Diploclinium and Begonia sect. Platycentrum. The former comprises tuberous species which occur along the Himalayan range. They die back during the dry season and their flowering time is strongly constrained by the onset of the monsoon. The latter comprises evergreen rhizomatous species some of w...
