Responses of plants to the length of the growing season were studied in an alpine snow-bed by setting five plots along a snow-melting
gradient. Performance and phenology were compared between the plots for five herbaceous species (Peucedanum multivittatum, Primula cuneifolia, Veronica stelleri var.longistyla, Solidago virga-aurea var.leiocarpa andPotentilla matsumurae). Performance characteristics measured were flower height, leaf height, leaf number, flower number and fruit number. In the
late exposed plots with short snow-free periods, fruit-set was reduced in many species due to the decrease in flower number
and/or the short growing season for fruit development.Veronica stelleri var.longistyla andSolidago virga-aurea var.leiocarpa, which decreased in flower and leaf numbers due to the short snow-free period, were sensitive to the short growing season.Peucedanum multivittatum was vigorous in the late exposed plots, but its slow flowering and fruiting prevented the fruit-set from developing in the
last exposed plot.Primula cumeifolia andPotentilla matsumurae, quick flowering species that maintained their flower number throught the snow-melting gradient, were considered the most
successful species in late exposed habitats. 相似文献

When carrying out experiments on the production of the edible mushroom Pleurotus sajor-caju in the Laboratory of Edible Mushrooms, Universidade Federal de Lavras, Lavras, Brazil, in the second half of 2007, the presence of beetles later identified as belonging to the species Mycotretus apicalis was verified. This is the first recorded instance of this insect in cultures of P. sajor-caju in Brazil. The larvae and adults of this insect feed on the fruiting bodies of commercial harvests, resulting in reduction in mushroom quality. To provide evaluation of the injuries caused by these insects, substrates colonized by P. sajor-caju were infested with 4, 8, 16, 32 and 64 insects per block of substrate being the qualitative and quantitative losses then noted. Despite the lack of an observed decrease in biological efficiency, the injuries caused by these insects affected the commercial quality of the mushrooms, which may result in economic losses. The results showed that infestations of 32 insects per 0.8 kg of substrate led to a depreciation in the prices of mushrooms meant to be sold. 相似文献

Antibodies against the cuticle surface of Trichinella spiralis muscle larvae were purified by means of immunoaffinity chromatography and incubated with ultrathin sections of muscle larvae. Major constituents of the parasite reactive with the purified antibodies included the cuticle surface, stichocyte alpha-granules, and the esophagus occupying substance of the muscle larvae. Thus the present data suggest that the cuticle surface is an antigenically different entity from the cuticle inner layers and its origin is likely stichocyte alpha-granules. 相似文献
