John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899. He wrote handbooks on many plant groups, including Amaryllidaceae, Bromeliaceae, Iridaceae, Liliaceae, and ferns. His published works includ''Flora of Mauritius and the Seychelles''(1877) and ''Handbook of the Irideae'' (1892). He married Hannah Unthank in 1860. Their son Edmund was one of twins, and his twin brother died before 1887. John G. Baker was elected a Fellow of the Royal Society in 1878. He was awarded the Veitch Memorial Medal of the Royal Horticultural Society in 1907. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoflavones
Isoflavones are substituted derivatives of isoflavone, a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the bean family, Fabaceae (Leguminosae). Although isoflavones and closely related phytoestrogens are sold as dietary supplements, there is little scientific evidence for either the safety of long-term supplementation or of health benefits from these compounds. Some studies have identified potential risks from high intake of isoflavones, such as in women with a history of breast cancer, but this concern has not been substantiated with high-quality clinical research. Organic chemistry and biosynthesis Isoflavone is an isomer of flavone, which is chromone substituted with a phenyl group in the 2-position. In isoflavone, the phenyl group is in the 4-position. Isoflavone is of liminted interest per se, but substituted derivatives are of nutritional interest. Substituted derivativ ...

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins ( flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non ...

Iris Perrieri
''Iris perrieri'' is a plant species in the genus ''Iris''; it is also in the subgenus ''Iris''. It is a rhizomatous perennial, from the Savoy Alps in southern France and recently in Italy. It has green, deeply ribbed, sickle shaped leaves, a slender stem with a branch (from the middle), 1–3 scented flowers that are violet or purple, with a white or pale blue beard. It is rarely cultivated as an ornamental plant in temperate regions, due to its rarity in the wild. It was once thought to be a form of ''Iris aphylla'', before cell (chromosome) analysis determined it to be a separate species. Description It is similar in form to ''Iris aphylla'', but has various differences including, stem branching, spathes, the falls, styles crests and seeds.British Iris Society (1997) It has a thick, compact rhizome, that has several branching buds. Like other bearded irises, it grows partially buried, horizontally across the ground. It has green, falcate (sickle-shaped) leaves, that are ve ...

Iris Variegata
''Iris variegata'', commonly known as the Hungarian iris, is a plant species in the genus ''Iris'', also in the subgenus ''Iris''. It is a rhizomatous perennial from eastern Europe.

Karyotype
A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well ...

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
