Hippophae
''Hippophae'', from Ancient Greek ἵππος (''híppos''), meaning "horse", and φάος (''pháos''), meaning "light", is a genus of flowering plants in the family Elaeagnaceae. They are deciduous shrubs. They are exceptionally hardy plants, able to withstand winter temperatures as low as . As ''Hippophae'' species develop an aggressive and extensive root system, they are planted to inhibit soil erosion and used in land reclamation for their nitrogen fixing properties, wildlife habitat, and soil enrichment. ''Hippophae'' berries and leaves are manufactured into various human and animal food and skincare products. Species and description The shrubs reach tall, rarely up to in central Asia. The leaf arrangement can be alternate or opposite. Plants of the World Online'' includes the following species: # ''Hippophae × goniocarpa'' is a natural hybrid of ''H. neurocarpa'' and ''H. sinensis'' which grows in mountainous regions in Nepal, Mongolia and China. # ''Hippophae gyants ...

Hippophae Rhamnoides
''Hippophae rhamnoides'', also known as sea buckthorn, sandthorn, sallowthorn or seaberry, is a species of flowering plant in the family Elaeagnaceae, native to cold-temperate regions of Eurasia. It is a spiny deciduous shrub. The plant is used in the food and cosmetics industries, in traditional medicine, as animal fodder, in horticulture, and for ecological purposes. Description and biology ''Hippophae rhamnoides'' is a hardy, deciduous shrub that can grow between 2 and 4 m high (between 7 and 13 ft). It has a rough, brown or black bark and a thick, grayish-green crown. The leaves are alternate, narrow and lanceolate, with silvery-green upper faces. It is dioecious, meaning that the male and female flowers grow on different shrubs. The sex of seedlings can only be determined at the first flowering, which mostly occurs after three years. The male inflorescence is built up of four to six apetalous flowers, while the female inflorescence normally consists of only on ...

Hippophae × Goniocarpa
''Hippophae'' × ''goniocarpa'' is a natural hybrid of the plant species ''H. neurocarpa'' and ''H. sinensis'', belonging to the family Elaeagnaceae, previously thought to be subspecies called ''H. goniocarpa'' subp. ''litangensis''. The Latin specific epithet In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin gramm ... ''goniocarpa'' refers to goniocarpus -a -um with angular fruits.D. Gledhill Also used by '' Eucalyptus goniocarpa'', '' Iris goniocarpa'' and '' Psychotria goniocarpa''. Description ''Hippophae'' × ''goniocarpa'' grows in mountainous regions in Nepal, Mongolia and China on mountain slopes, river banks, flood lands and valley terraces. The growth altitude is typically between . It is distinguished by the young branchlets and the lower surface of leaves. References {{DEF ...

Elaeagnaceae
The Elaeagnaceae are a plant family, the oleaster family, of the order Rosales comprising small trees and shrubs, native to temperate regions of the Northern Hemisphere, south into tropical Asia and Australia. The family has about 60 species in three genera. They are commonly thorny, with simple leaves often coated with tiny scales or hairs. Most of the species are xerophytes (found in dry habitats); several are also halophytes, tolerating high levels of soil salinity. The Elaeagnaceae often harbor nitrogen-fixing actinomycetes of the genus '' Frankia'' in root nodules, making them useful for soil reclamation. This characteristic, together with their production of plentiful seeds, often results in the Elaeagnaceae being regarded as weeds. The stems and leaves are covered with silvery brown or golden hairs which are either peltate or scaly. ''Shepherdia'' and ''Hippophae'' are unisexual, the female and male borne on different plants (dioecious). There are no petals, the perian ...

Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen Fixing
Nitrogen fixation is a chemical process by which molecular dinitrogen () is converted into ammonia (). It occurs both biologically and abiologically in chemical industries. Biological nitrogen fixation or ''diazotrophy'' is catalyzed by enzymes called nitrogenases. These enzyme complexes are encoded by the ''Nif'' genes (or ''Nif'' homologs) and contain iron, often with a second metal (usually molybdenum, but sometimes vanadium). Some nitrogen-fixing bacteria have symbiotic relationships with plants, especially legumes, mosses and aquatic ferns such as '' Azolla''. Looser non-symbiotic relationships between diazotrophs and plants are often referred to as associative, as seen in nitrogen fixation on rice roots. Nitrogen fixation occurs between some termites and fungi. It occurs naturally in the air by means of NOx production by lightning. Fixed nitrogen is essential to life on Earth. Organic compounds such as DNA and proteins contain nitrogen. Industrial nitrogen fixat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
