Are black tomatoes genetically modified?

Black tomato is an infinite hybrid generation of excellent seeds introduced from abroad, which has the advantages of good taste, good coloring, high sugar content, good harvest uniformity, strong disease resistance, etc., and its nutritional value is higher than that of ordinary tomatoes, and the market price is also more expensive. But many people are worried that black tomatoes are genetically modified. Let's take a look at whether black tomatoes are transgenic or not.

Are black tomatoes genetically modified?

Black tomatoes are not genetically modified. Black tomato is native to South America and is a treasure of the tomato family. It is named because its fruit color and fruit are red and black. Its fruit is used for both medicine and food, with strong fruit aroma, moderate sour and sweet taste, high nutritional value, especially suitable for fresh food. It also contains a lot of lycopene and rich vitamin C and antioxidants, which can nourish yin and protect kidney and whiten skin, lose weight and lose weight.

The difference between Black Tomato and Tomato

The main results are as follows: 1. Compared with common tomato seedlings, black tomato has darker leaves, which may be the expression of its genetic characteristics on seedlings.

2. Black tomato varieties have stronger cold resistance than common tomatoes, which may be related to the cooler climate of their origin, especially the Russian series, which is more suitable for the development of low cold areas.

3. The appearance and pulp of black tomato are red and black, there are dark brown black, light brown black, red black and so on, which is mainly related to the accumulation of a large amount of melanin in its fruit, which is also the key to its higher medicinal efficacy than ordinary tomato.

4. The skin of black tomato is thinner, the flesh is softer and more palatable, which is more suitable for the elderly and patients.

5. The nutritional value and health care effect of black tomato have been internationally recognized, which has the effect of nourishing yin and strengthening yang and preventing body aging, which is related to its high content of antioxidants.

6. The planting technology of black tomato using flat-shed pruning is more conducive to sugar accumulation, which is the current development trend of planting functional fruit. The fruit is more aromatic than ordinary tomato and can be cultivated as a variety of fruit tomato.

7. Black tomatoes have higher economic value. At present, there are imports from abroad in Shanghai, a big city in China, but the price in supermarkets is very high, 3645 yuan per jin, ranking among the ranks of high-grade fruits.

Identification methods of transgenic vegetables

1. Size: without the uneven shape of traditional vegetables, it is generally uniform in size, generally long in shape, bright in color and tender in texture. For example, peas should be shaped like animal internal organs, a little flat, with a waistline, but the existing soybeans are all sweet, like peas, and the yield is very high.

2. Taste: there is no original and authentic taste of traditional vegetables, whether the smell or taste before or after cooking is obviously different from that of traditional vegetables. Traditional corn is generally "corn, white corn, slightly sweet, but now popular sweet corn, its sweetness is very high, like adding honey." Sweet corn grain has less wax on the surface, delicate taste, and some are waxy.

3. Yield: transgenic vegetables are generally in the first few years, and their yield is much higher than that of traditional vegetables.

4. Color: different from traditional colors, such as colored cotton, black rice peanuts, purple sweet potatoes.

5. Pests: all vegetables that pests like to patronize are not genetically modified, and vegetables that pests are afraid of, that is, vegetables with no pests, or few pests, are absolutely genetically modified.

6. Season: non-local seasonal vegetables, one of the major characteristics of all kinds of vegetables is that they have strong seasonality and regionality. Some non-local seasonal vegetables are obtained by transplanting cold-tolerant or high-temperature tolerant genes, such as out-of-season winter jujube.

7. Seed retention: genetically modified vegetables are generally difficult to keep their own seeds.
