Ginkgo

Ginkgo is the only extant species of plant in the order Ginkgoaceae, and its name comes from the transliteration of the Chinese word for silver fruit.

To this day, the scientific community continues to debate where to place this unique species. Varying from one academic organization to another, there are usually three classifications. Some believe that it should be classified as a conifer and Cordaitales; others believe that it should be classified as an evolutionary branch with Peltaspermum and Thuja; and still others believe that Ginkgo belongs to a different paraphyletic group under a broad class, platysperms, along with Thuja, Peltaspermum, and Callistophytales. Botanists find it difficult to localize because ginkgo has the same reproductive mode as thujaplicas and the same growth pattern as conifers.

Seeds of Ginkgo: Like thuja, the seeds of ginkgo are borne on highly evolved leaves; whereas the seeds of conifers are attached to evolved branches. As mentioned earlier, ginkgo and thuja have similar ways of reproducing. Both species have motile sperm, which is very rare in seed plants. Both ginkgo and thuja are dioecious, i.e., the female and male reproductive organs are located on different plant bodies. There are also anatomical similarities between mature ginkgo seeds and thuja seeds. For example, the seed coat is divided into two parts, the hard seed coat and the thin seed coat. In contrast, conifers and angiosperms have only one continuous seed coat. The only difference between ginkgo and sundew is that the vascular system of ginkgo includes two parts that traverse the peridium. In addition, Nilssonicladus of thuja has a foliar bifurcation pattern similar to that of ginkgo.

The reason for associating ginkgo with conifers is that both have axillary branched leaves. And ginkgo has an incipient woody striated outer mouth similar to conifers. Both have woody trunks, and woody roots that serve as a base for self-growth as well. In short, both ginkgo and conifers are trees with long internodal segments, whereas sundews do not exhibit this growth characteristic and have only short internodal segments.

How can ginkgo be distinguished from other gymnosperms? All ginkgos, whether surviving or dead fossils, have fan-shaped leaves. In fact, the leaves are the best way to identify a ginkgo, and the same holds true for fossilized ginkgos. All ginkgos also have leaf veins similar to those of dicotyledons.

The pistachio is the fruit of the unnamed tree, a deciduous tree of the lacquer family, which reaches up to 10 meters in height, and is a long-lived tree, with an age of up to 300 to 4O0 years. Flowering in May each year, September results. Harvested when the rind splits, exposing the green kernel. Its kernel is a highly nutritious food, containing carotene, vitamins E, C, B 〓, B 〓, niacin, as well as egg quality, minerals and so on. The oil content of the seed kernel is as high as 45?1%, and the cold pressed oil can be used as high level brain oil and raw material for cakes and artificial cheese. Pistachio is also nourishing food medicine, it is sweet and non-toxic, warm kidney and spleen, being beneficial to the deficiency, adjusting the gas, can treat neurasthenia, swelling, anemia, malnutrition, chronic diarrhea and other diseases." Pistachio" that is "happy to relieve depression" effect and name.

Pistachio

Pistachio in our country as a therapeutic tonic application, has a history of more than a thousand years. Tang Dynasty, a Persian descendant called Li Xun, wrote a special collection of overseas drugs, "Sea Drugs Materia Medica", the book has pistachio, he said: "In fact, the shape of hazelnut, the Persian family called for pistachio." Because it came from the West, another pharmacist in the Tang Dynasty, Chen Zangqi, in his book "Gleanings from the Materia Medica", the book, and then called it "Hu Hazelnut". To the Yuan Dynasty, the imperial physician Hu Si Hui in his special dietary therapy monograph written for the emperor, "Drinking meals are about to be", is to take its translation, known as "must answer". Today, China's Xinjiang minority areas, Arab and Islamic countries and Japan, etc., still call it "Bisida".

The pistachio is native to Turkey, 3000 years ago has been cultivated, and later expanded by the Mediterranean to Afghanistan, the Middle East, South Asia. The l century A.D. from Syria to Rome, and in the 18th century to the United Kingdom. The United States developed later, nearly a century, but its development is faster, in California, Arizona, Texas and other states are cultivated, the production is very large. Therefore, most of the pistachios we see in food stores today are imported from abroad. However, now there are also cultivated in Xinjiang and other places in China, only the production is not high. In our country to develop the cultivation of pistachios, the prospect will be very attractive.
