English walnut (Juglans regia L)
Human health benefits of the Black walnut by comparing its compositional similarities and differences the English walnut.
Walnuts are a rich source of the tocopherols with γ-tocopherol being the predominant Vitamin E isomer
Walnuts also contain considerably high levels of non-cholesterol sterols known as plant sterols or phytosterols
The actual distribution of walnut in Europe resulted from the combined effects of expansion/contraction from multiple refugia after the Last Glacial Maximum and its human exploitation over the last 5,000 years.
The genetic structure of the 91 sampled walnut populations was evaluated.
After the last glaciation J. regia survived and grew in almost completely isolated stands in Asia
Walnut can benefit from being planted in mixed stands, particularly with nitrogen-fixing species
Walnut growth for at least the first seven years after planting was greatly enhanced when accompanied by E. umbellata
Overall, walnut survival was excellent.
English walnuts (Juglans regia L.) are rich in numerous phytochemicals, including high amounts of polyunsaturated fatty acids.
Feeding studies from our laboratory have shown that dietary supplementation with walnuts can improve memory, cognition, and motor function in aged animals
plays an important role in reducing the inflammation and oxidative stress in the aging brain
It's interesting that English walnut has side effects too. When applied to the skin English walnut bark is possibly unsafe. It contains a chemical called juglone that can irritate the skin.
The nut of the English walnut contains chemicals called fatty acids, which might be useful as part of a cholesterol-lowering diet
contains chemicals that can expand blood vessels, possibly improving circulation and the way the heart works
Juglans regia has been widely used in traditional medicine for treatment of diarrhea, sinusitis, stomachache, asthma, eczema, skin disorders, and various endocrine diseases such as diabetes mellitus, anorexia cancer and infectious diseases
Chemical structures of compounds isolated from Juglans regia L.
The walnut is classified as a strategic species for human nutrition
Due to high contents of fats, proteins, vitamins and minerals walnuts are nutrient-rich food.
Walnuts can nourish brain cells to improve human memory. Other parts of the plant were used to make different medicines.
seeds used as walnuts is provided to explore their potential and to advance research
Juglans species have diverse chemical constituents such as diarylheptanoids, quinones, polyphenols, flavones.
The bud burst, leafing, leaf yellowing and defoliation dates of seventy-five genotypes obtained from nine different walnut cultivars and their parents were determined in this research
Juglans regia L. which is native to Central Asia, has been widely cultivated throughout Europe over millennia as
a multipurpose tree
Walnut needs specific condition to survive
It requires warmth, shelter and sufficient light and requires soil with pH level between 6 and 7.5.
Toxic levels of Cr were measured in the roots of Juglans regia
Human activities result in the release of toxic elements
It was also measured in the leaves
Walnut (Juglans regia L.) is one of the most economically important nut trees and growing in temperate areas worldwide
Walnut is cultivated in temperate regions worldwide for its wood and nuts
Walnut is grew in completely isolated stands
In autumn 1996, adult Juglans regia L. trees cultivated in Piedmont which is north-west of Italy showed irregularly shaped cankers along the bark
A watery dark coloured exudale was also observed
When the phelloderm was removed extensive necrosis of the tissues below was observed
The highest correlations
were detected between nut height and nut width, and between nut weight and kernel weight.
English walnut is a medium large deciduous tree
Can live upto 150 years
Concentrations were analysed in roots,
branches, leaves, fruits, and seeds.The ability of J. regia to store large quantities of β-HCH in wooden and leafy parts.
Valuable for food and wood manufacturing
Concentrations were analyzed in roots,branches,leaves and fruits.
Juglans regia L worth for both its nut and wood. It is an ecologically important temperate tree species which native to the mountainous regions of central Asia.
Male and female reproductive organs are borne in different petalless flowr clusters on same trees.
The trees have long leaves with 5 to 23 short stalked leaflets.
