Origin for buy: Central Asia, mountainous regions west of the Himalayas meaning: Kashmir, Tajikistan, Kyrgyzstan. Wild walnut trees (for that meats) can still be found in these countries in more or less degraded forests. Traders using the Silk Road spread throughout Europe before being introduced to South America in the 16th century, and from the 17th century to North America. was introduced in Key Features: Walnuts have a different growth cycle than most other fruit trees. It germinates in late April, flowers in May, matures from late September to the end of the month, and drops its leaves in late October. . . The fruiting body has her three types: apical, intermediate, and lateral branches, with a continuous gradation between these types. Nuts are located only at the ends of the fruiting branches (terminal fruiting) or grouped into sleeves along the fruiting branch (lateral branches). The latter yields much higher yields than top-bearing cultivars. Walnut is a dioecious plant with flowers of the same sex on the same tree. Male inflorescences form earrings, female inflorescences consist of single flowers or groups of 2-3 flowers.
The male and female flowers of the tree are confused in time. Male flowers may appear earlier than female flowers, or vice versa, depending on the cultivar. Therefore, walnuts are self-sterile, but less likely to self-pollinate for most varieties. Therefore, it is necessary to prepare at least 2-3 varieties that can be pollinated. Walnut female flowers are free of insects. Therefore, pollination takes place only by wind. The walnut fruit consists of an outer shell: a shell that surrounds the nut with an oily shell containing almonds and kernels. In France, walnut trees are found throughout the territory and grow mainly in Dauphine (Isère and Drôme), Périgord (Dordogne, Lot, Corrèze, Charente). Recently, it has also been cultivated in the Garonne Valley. The region of origin has his two controlled appellations, Noy de Grenoble and Noyet Cerneaux du Périgord. Main varieties: 'Flanquette': grown on terraces overlooking the right bank of the Isère and is the most cultivated variety. This fairly hardy walnut tree has a late budding, semi-upright appearance that helps it avoid late spring frosts. is determined by Flankets are relatively immune to bacteriosis and anthracnose, and their grains are of excellent quality. Undoubtedly the best French variety with maximum fruit set. - Lara®: French variety obtained from American pine seedlings. As an adult, it is a medium-vigorous tree with a semi-upright or semi-spreading habit. This cultivar has a very early fruit set and a very high yield due to the side shoots. Relatively early germination to flanket. Therefore, depending on the year, it may be affected by the coldness of spring. Lara is a cultivar that is very susceptible to fruit bacteriosis in some years.
–Fernor®: Developed in 1978 by his INRA in Bordeaux by crossing his Franquette with Lara®. It is a semi-upright, medium-sized tree. Fernoor bears fruit on the lateral shoots, which results in faster fruit set and higher yields. The buds bloom late and are male flowers. This is a variety that is less susceptible to bacteriosis and less susceptible to anthracnose. Its maturation is very slow. Fernor® walnuts are perfectly elongated and are reminiscent of franchettes, a grain of superior quality. Difficulty: Walnut trees are very sensitive to spring cold as soon as they burst.When temperatures drop below -1.5 or -2°C, the male and female flowers are severely damaged or die off. Varieties grown in France germinate after April 15th. Autumn frosts during leaf drop (late October to early November) are very detrimental to walnuts, especially young plantations. Walnut trees require 700-800 mm of precipitation per year, which is well distributed in summer. Nutritional Properties: Walnuts are recommended for fighting cardiovascular disease. It is also a fruit with unique energy properties such as vitamins, protein, fiber and magnesium. cultureDifficulty: None.Soils: Deep, clayey, limestone soils are most desirable. However, soils that are too alkaline and contain more than 5% activated limestone increase the risk of iron chlorosis. In winter, in heavy, poorly drained soils, excess moisture causes root suffocation, often leading to tree death.Walnut trees are particularly susceptible to this incident. Planting/Planting: Currently, Juglans regia L. walnut seedlings remain the rootstock of choice in most situations: In most cases, induction rootstocks are suitable. The use of walnut leavesMild inflammation and itching of the skin, increased sweatingliquid extract Follow the manufacturer's dosage.Dry leaves.
Boil 2-3 g of dry leaves in 100 ml of water over low heat for about 15 minutes. Strain the broth and use it in the form of compresses or baths. Repeat twice a day if necessary. History of walnut leavesThe common nut is often called "Iranian nut". In fact, it was in Iran (now Iran) that we began to cultivate it, or at least to receive the ancestors of our modern species. Walnut leaves have been used medicinally for thousands of years. In Asia they have been used to treat eczema, herpes, tuberculosis, syphilis and cancerous lesions. In Europe, they were treated with inflammation of the skin (skin), hemorrhoids, inflammation of the eyelids, abscesses, excessive sweating of the feet and hands. In France, it is still used to treat scalp conditions, dandruff, sunburn and other superficial burns, and various minor skin conditions. Walnut skin has also been used as a laxative and laxative (blood purifier), especially among Americans. The latter used the bark of species native to North America (J. nigra and J. cinerara), which contain almost the same active ingredients as the common walnut (J. regia). These casings have also been used to treat infections and inflammation of the digestive system caused by intestinal parasites. Pharmacists also use walnut bark (twig bark) for its antiseptic and antifungal properties. Recently, researchers have shown great interest in the fruit of the walnut tree, the nut, which contains a particularly interesting oil due to its unique profile of omega-3 and omega-6 essential polyunsaturated fatty acids. This makes nuts a valuable food product for the prevention of cardiovascular and coronary heart disease. See our "Nuts" tab for more information. Walnut Leaf ResearchIt is known to be used for skin inflammation and excessive sweating. The German Commission E recognizes the topical use of walnut leaves for the treatment of benign inflammations of the skin and excessive sweating (hyperhidrosis) of the hands and feet.
Clinical trials to evaluate the effectiveness of falcon leaves for these purposes have not been conducted. These effects are generally attributed to the astringent action of the tannins they contain. The antimicrobial and antifungal properties of certain components of walnut leaves, in particular juglone, have been confirmed by several laboratory tests 1-3. Another one. Researchers are also interested in the antioxidant and antidiabetic properties of walnut leaves. The data remains very preliminary for the moment 4-7. Precautionary measuresAttentionWhile tradition recommends taking a leaf or bark decoction orally as a laxative or expectorant, some experts strongly recommend the topical use of juglone due to its possible toxic effects. Long-term daily consumption of products containing juglone has been associated with manifestations of leukoplakia (local discoloration of the mucous membranes, usually precancerous) and cancer of the tongue or lips. Commission E advises against covering the decoction of walnut leaves with a waterproof dressing and advises against applying the decoction to large areas of the body. Laboratory tests show that juglone and plumbagin, two compounds present in walnut leaves, inhibit the growth of cells of the superficial layer of the skin (keratinocytes) and appendages (nails, hair, body hair). Therefore, walnut leaves should be used with caution even for external use.
