The facts of organic evolution are vividly exemplified in the multifarious manifestations of the living units, e.g., the species, each of which constitutes a compromise of diverse morphosystems at various levels of evolutionary by: 3.
Pollen morphology & pollen fertility estimation of three medicinal species belonging to genus Hypericum L. from flora of Kaghan valley, Northern Pakistan was investigated by light Pollen grains of Western Himalayan plants book scanning electron microscopy for the first time.
The species are Hypericum elodeoides Choisy in, Hypericum oblongifolium Choisy, and Hypericum perforatum L. Pollen morphological characteristics with considerable Author: Paras Mazari, Quanru Liu, Mir Ajab Khan, Sehrish Sadia, Latif Ahmad. In the apiaries of the western Himalayan region (Kumaon and Garhwal hills) of Uttar Pradesh, the honey is harvested twice in a year i.e.
in autumn and spring. Out of 12 spring samples of honey analysed, there are 10 unifloral and 2 multifloral samples.
The dominant entomophilous pollen types in unifloral samples areBrassica, and Rosaceae-Prunus by: 3. Studies of regional Quaternary pollen floras have been listed per continent, including books, series of papers published under a common title, and miscellaneous papers.
Regional pollen floras include studies of the pollen, and/or spores, of urban areas, national parks, or larger geographical or phytogeographical areas that cover significant Cited by: Textbook of Genetics and Evolution by Nair, P.K., Achar, K.P. and a great selection of related books, art and collectibles available now at The pollen morphology of 15 Onosma L.
species has been examined by SEM for the first time from Pan Himalayan regions of Pakistan and China. the pollen grains are single, isocolpate, radially.
The Laricoideae are a subfamily of the Pinaceae, a Pinophyta division family. They take their name from the genus Larix (), which contains inside most of the species of the group and is one of only two deciduous genera of the pines complex (together with Pseudolarix, which however belongs to a different subfamily, the Abietoideae).Ecologically important trees, the Laricoideae form pure or Class: Pinopsida.
Here, pollen records of the variability in ISM precipitation and their interpretation in terms of vegetation and climate change from two wetlands (Gharana and Nanga; Ramsar sites) of the Western Himalaya (India) is presented.

The peony or paeony is a flowering plant in the genus Paeonia, the only genus in the family are native to Asia, Europe and Western North America.
Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further : Angiosperms.
Sublethal and other deleterious properties were expressed in all plants of the next generation after selfing. Another method is to screen pollen grains for recessive genes, which are detectable in the haploide phase.
Only a few characters expressed in pollen grains (for example amylose/amylopectin ratio) could be scored in this way. Pollen is the microscopic grains produced by the male parts of the plant when it flowers. These need to be carried to the female parts of the plant, in order to reproduce.
Pollen grains are. Of the other sections, four monotypic sections (sections Steenhanmera, Neuranthia, Typomertensia, and Mertensianthe) showed pollen structures similar to each other. Pollen grains in section Eumertensia had some variations in size and ornamentation, especially in the species distributed in western North by: 3.
Pollen grains as aeroallergen are well studied from across the world and are important cause of pollinosis. Respiratory system is the direct target organ of airborne pollen taken in by inhalation.

Papaver / p ə ˈ p eɪ v ər / is a genus of 70– species of frost-tolerant annuals, biennials, and perennials native to temperate and cold regions of Eurasia, Africa and North America.
It is the type genus of the poppy family, : Papaveraceae.

In spite of their high meiotic instability and comparatively moderate pollen sterility, the seed production in these plants was satisfactory (%), suggesting that at least some part of the seed might be produced apomictically.
DISCUSSIONCited by: 3. Pollen fertility– Pollen fertility was estimated through stainability tests for which anthers of mature flowers were squashed in glyceroacetocarmine mixture () or 1% aniline blue dye.

In: Benjamin J. Kaiser (ed.) Pollen: Structure Types and Effects, pp. Nova Science Publishers, Hauppauge, NY, USA. Indeed, seed set was invariably close to % in all studied localities, and the populations did not seem to be pollen-limited.
In such situations, if plants bear few ovules per flower and thus require relatively few pollen grains for a full seed set, the probability that two visitors are equally effective pollinators increases (Johnson et al Cited by: 2.
In the Eastern Cordillera of Bolivia, pollen grains travel from near and far to become sandwiched in layers of snow in the Andean mountaintops, ultimately becoming trapped as the layers turn to ice.
Such is the case on the Illimani Glacier, which towers approximately 2, meters over. Photo-album of plants of Eastern Himalaya, by Members of Botanical Expeditions to Eastern Himalaya, University of Tokyo.

New or noteworthy flowering plants from Eastern Himalaya.Pollen grains: medium-sized ± 9µ in diameter round mostly tetracolporate; some are tricolporate with granular exine ing: a long flowering period beginning in September and lasting to dian butter tree is among the few plants from which a sweetening material can be harvested without the aid of honeybees.In fact, a study in the Annals of Allergy, Asthma and Immunology of airborne pollen counts in Midwestern states found that in the month of August, when most outdoor cannabis plants begin to mature, 36% of all pollen came from cannabis plants.
And that pollen can travel many miles. (See "Buffer Zones: How Far Can Cannabis Pollen Travel" below.)Author: Marguerite Bolt.
