Why is the watermelon red? As the title suggests, thank you

Red flesh watermelon contains lycopene, and yellow meat contains lutein, both of which are antioxidant foods with anti-cancer and anti-aging beauty effects, which are beneficial to the human body. Red watermelon has higher calories than yellow watermelon fruit is a gourd fruit, which is developed by ovary fertilization. The whole fruit is composed of three parts: the skin, the pulp, and the seed.

Among them, the peel is developed due to the wall of the house, the flesh is developed from the placenta, and the seeds are developed from the ovules after fertilization Different varieties of watermelons have a variety of shapes, sizes, skin colors, patterns, and flesh colors. These characteristics are often used as the main basis for identifying varieties. First, the size of the fruit is mainly determined by the size of the ovary and the development of the fruit about 20 days after flowering.

In the first 4 to 5 days of female flowers, it is a critical period for the fruit to sit; The next 15 to 20 days is the main period of fruit volume increase, and the growth amount is about 90% of the whole melon weight. 1o days before fruit ripening, the volume increases slowly, mainly due to changes in the internal composition of the fruit. Therefore, before and after flowering, pruning and pruning should be done in time, fertilizer and water should be strengthened, and artificial assisted pollination should be used to improve the rate of melon setting. Second, watermelons have different shapes, including round spherical shapes, high rounds, short ovals and oblong ovals.

Generally, longitudinal growth is dominant in the early stage of growth, and transverse growth is dominant in the middle and late stages. In the early stage of fruit development, if it encounters low temperature, dryness, insufficient light, and excessive vegetative growth, it often produces deformed fruits. Third, the thickness of the peel is also an important indicator to reflect the advantages and disadvantages of the variety.

In addition to the different varieties, it is also related to the node position of the melon, and the fruit with low node position is small, flat, thick, hollow, and has many fibers. This is related to the low number of leaves, insufficient nutrient accumulation and low temperature in the early stage of fruit development. In this regard, the first melon is removed in production, and the second and third melons are selected.

Among them, the third melon is better, and the melon is large and thin. However, considering the precociousness and insurance, it is still advisable to keep the second melon. Fourth, the color of melon pulp is related to the quality and the differences in consumption habits in different places.

Its different colors are related to the different pigments contained in melons. The red pulp contains lycopene and carotene, which are mainly determined by the amount of lycopene content, resulting in different colors such as light red and bright red. Yellow pulp contains various carotene; White flesh contains flavonoids, which are combined with various sugars to form glycosides and exist in cell fluid.

Watermelons are not necessarily all red, but also white and yellow.

This kind of watermelon is specially stored by the seller for sale during the Spring Festival or off-season, it is picked when the individual weight of the watermelon reaches and is not ripe (when the watermelon is still white), stored and now taken out for sale. The flesh of the watermelon is dark red, and it is basically cooked when it is stored.

The watermelon fruit is a gourd fruit and consists of an ovary.

Fertilization develops. The whole fruit is composed of three parts: the skin, the pulp, and the seed. Among them, the pericarp is developed due to the atrial wall, the pulp is developed from the placenta, and the seed is developed from the ovule after fertilization.

Different varieties of watermelon have a variety of shapes, sizes, skin colors, patterns, and flesh colors. These characteristics are often used as the main basis for identifying varieties.

One is that the watermelon is bad, the watermelon has a peculiar smell, and the dark red color that becomes soft indicates that the watermelon is bad. The other is the variety, the red watermelon variety, whose flesh color is dominated by the content of lycopene, appears dark red. <

One is that the watermelon is bad, the watermelon has a peculiar smell, and the dark red color that becomes soft indicates that the watermelon is bad. The other is the variety, the red watermelon variety, whose flesh color is dominated by the content of lycopene, appears dark red.

Because the pulp contains a large amount of lycopene, and the degree of red watermelon is mainly determined by the content of lycopene, which is a carotenoid naturally found in plant fruits and vegetables, not only watermelon, red pepper, and tomatoes contain a large amount of lycopene.

Morphological characteristics: annual vines; The stems and branches are stout, with obvious grooves, and are covered with long, dense white or light yellowish brown pubescence. tendrils stout, pubescent, 2-ambiguous, petioles thick, 3-12 cm long, coarse, with inconspicuous grooves, densely pubescent; Leaves papery, contour triangular-ovate, whitish-green, 8-20 cm long, 5-15 cm wide, two masks with short bristles, more on veins and back, 3 deeply lobed, middle lobes longer, obovate, oblong-lanceolate or lanceolate, apex acute or acute, lobes pinnate or double pinnate shallow or deeply lobed, margins wavy or sparsely toothed, the terminal lobes are usually shallowly serrate, apex obtuse rounded, the base of the blade heart-shaped, sometimes forming a semicircular bend, the bend is 1-2 centimeters wide and the nucleus is 1-2 centimeters deep.

Because the pulp contains a large amount of lycopene, and the degree of red watermelon is mainly determined by the content of lycopene, lycopene is a kind of carotenoid naturally found in plant fruits and vegetables, not only watermelon, red pepper, tomatoes contain a lot of lycopene. <

Because the pulp contains a large amount of lycopene, and the degree of red watermelon is mainly determined by the content of lycopene, solanine is a kind of carotophanoid that naturally exists in plant fruits and vegetables, not only watermelon, red peppers, tomatoes contain a large amount of lycopene.
