If you haven't been hit too hard by mangoes in summer, it's not like you've been to Guangzhou. Every May to July is the ripening season for mangoes, and many citizens find that many trees on both sides of Guangzhou's roads are covered with green mangoes recently. These green mangoes not only look bright in color, but also smell very sweet. Some foodies can't help but have a "crooked mind": pick it! Eat it! But can these mangoes be eaten? ▲ Image source: The official WeChat answer of Guangzhou Municipal Health Commission is - cannot eat! Green mango trees, commonly known as "green mango trees", are relatively wind resistant and grow quickly. They are commonly used for planting sidewalks and shade trees. At an intersection next to a community on Jiangwan Road, Haizhu District, Guangzhou, there are some mango fruits falling off everywhere on the ground. Near Dashatou Second Road in Yuexiu District, many green mango trees on the street have begun to bear fruit. Mango trees are common on the roadside in both new and old urban areas of Guangzhou. Why can't green awns on the roadside be eaten? 1. Mango trees planted in green belts are green plants, and fruit hanging branches are also part of the urban landscape, without edible value. 2. Due to being mostly planted on the roadside, leaves and fruit peels absorb exhaust and dust from passing vehicles for a long time, and a large amount of harmful substances such as heavy metals accumulate in the fruit flesh. 3. Daily Pest control for greening maintenance requires necessary spraying, and there will be pesticide residues. Experts remind that picking and consumption are not recommended! Zeng Songjun, a researcher of the South China National Botanical Garden, said that there are all kinds of heavy metals in the green awn, and the pollution will be more serious. He advocated that the public should not pick and eat, and that the green institutions should deal with them in a unified way. In addition to being inedible, it is worth noting that the act of picking green awns without permission and damaging the greenery will be subject to certain penalties. According to the relevant provisions of the Guangzhou Greening Regulations, it is prohibited to climb, break, nail, or tie trees in green spaces to damage their roots, trunks, and bark; It is prohibited to pick flowers, fruits, branches, and leaves, and trample on green spaces. Violations will result in a fine of not less than 20 yuan but not more than 50 yuan. Green mango has less flesh and a astringent taste with low nutrition. As a local tree in Lingnan, mango trees have the characteristics of neat tree shape, lush branches and leaves, large crown and thick shade, straight trunk, rapid growth, and easy maintenance. They are excellent roadside tree species and are widely planted in various cities of the Pearl River Delta region. Green mangoes have greening and aesthetic effects, as well as purifying the environment and absorbing harmful gases, adding more charm to the city. However, unlike fruit mangoes, which are carefully cultivated and protected, they do not have much flesh. As for the green mangoes that fall to the ground, there is no need to worry. Mango trees on the streets are generally maintained on a daily basis, and the green management department will trim the branches of the mangoes. The pruned fruits will be destroyed as green waste. Although the varieties of green mango and fruit mango are of the same family and have the same root system, their cultivation methods are completely different in terms of soil, fertilizer, water, etc. The fruit mangoes on the market adopt the method of branch and shoot grafting, which belongs to asexual reproduction and generally does not undergo variation, and can maintain the excellent characteristics of the variety. Green mangoes grow from the germination of seeds and undergo mutations. The fruits are green and small, with a astringent taste, and are far less nutritious than edible mangoes.
