How can we tell if tomatoes are hormonal? What are the selection techniques?

The hormone used by tomatoes is generally ethylene or ethephon, which can promote germination, inhibit flowering and make the fruit bigger and more perfect. Therefore, some crop growers will spray ethylene during the growth and development of tomatoes in order to get on the market as soon as possible and sell them at a good price. Naturally ripe tomatoes are generally round and full, with a well-balanced color and a thin layer of powder on the surface, which is covered with pure white dots. If the fruit body is moderately soft and hard, and some fruit pedicels are light bluish green, it shows that this tomato is fresh and has a good taste. Tomatoes are nutritious and have a unique taste. They can be eaten directly as fresh fruits or as cooked vegetables and fruits.

How to tell whether tomatoes have added growth hormone: The maturity of tomatoes is soft rather than hard. If it thinks there is a kind of tomato with obvious hard core, it is best not to buy it. Look: Perfect tomatoes are all red, and pale yellow varieties are apricot yellow. If the color tone is uneven, it is best not to choose.

Of course, the tomato with "crooked melon and cracked jujube" is likely to be sweeter, but if the fruit has obvious protrusions, you can not choose it; If it is a ripe tomato, it looks irregular and uneven in green and red, often angular, with a high bottom and much lighter weight. Normal tomatoes are tender and plump in color, and there may be some gray outside, which will be very soft to pinch. There will be light turquoise in the pedicle. Naturally ripe tomatoes will feel soft and full of water, which is also the primary criterion to distinguish whether tomatoes are ripe or not.

Anyone who has touched a tomato with a little hard skin can say that it is not perfect, and no matter how bright the color is, it is a tomato that has been pushed red. Naturally mature tomato fruit bodies have no prominent sharp edges and corners, and are all smooth. Its skin is red with a little pink, and it is emerald near the pedicle. Look carefully, the skin has milky white spots, which are hard and soft to pinch. When you open it, you will see how round the juice is and it looks rustling. There are perfect seeds in the pulp. Bite a little sour, a little sweet, a little rustling, and the taste is stronger.
