Which part of the world is the best place to grow coffee trees?
A survey by the Royal Botanical Gardens in London has found that climate change is having an impact on the coffee people depend on. Coffee trees will gradually die out with climate change, such as Arabica, the most popular coffee variety, which is likely to disappear by 2080. According to a survey by British scientists, it is only wild coffee trees that are more likely to die out. Coffee trees planted by people are actually "close relatives" of wild coffee trees. According to research published in PLOS ONE, the public science journal, Davis combines data from field trips to Africa with computer simulations of different climates to understand how climate change will affect a variety of wild coffee plants. His study focuses more on wild coffee trees in Ethiopia, which are genetically closer to the identification of Arabica coffee trees:
1. The seed coat of small fruit coffee has been removed, oval or oval in shape, 8-10mm in length, 5-7mm in diameter, 3-4mm in thickness in the middle, raised on the back, flat on the ventral surface, with slightly curved longitudinal groove and paper seed coat marks. Raw products are yellow or dark green; baked products are dark brown with special aroma and slightly bitter taste. Astringent.
2. The seeds of medium fruit coffee are slightly larger, ovoid, 9-11mm long, 7-9mm in diameter, raised abaxially and flat on the ventral side.
3. Coffee seeds with big fruit are oblong, about 15mm long, about 10mm in diameter, smooth.
Microscopic identification: small fruit coffee seed powder characteristics: the raw product is yellowish green and the baked product is brown.
① has many brown lumps of different sizes.
② fiber is slender.
③ stone cells are rectangular and round, with a length of 200 μ m and a diameter of 20-40 μ m.
④ endosperm cell wall is thick, pit can be seen, containing protein grains and fat. Physical and chemical identification to take a little powder of this product, put on the slide, add a little water, heat, wait for the water to dry, add 2 drops of benzene, after drying, there are many yellowish needle crystals along the edge of the slide.

However, not all the land located in this area can produce good coffee trees. The ideal planting conditions of coffee trees are as follows: the temperature is between 15 ℃ and 25 ℃, and the annual rainfall must reach 1500 mm to 2000 mm. At the same time, the rainfall time should be in line with the flowering cycle of coffee trees. Of course, in addition to the coordination of seasons and rainfall, there should be fat work.
