Today's tomatoes are always hard to keep for a long time and are not bad for two reasons.

Nowadays, tomato hardness is actually one of the storage quality of tomato, which is related to tomato breeding, and the other is related to the current tomato harvest system. It is precisely because of these two points that the storage quality of tomatoes is greatly enhanced. It can also be said that this is developed with the process of urbanization in our country. For example, in the past, China's urbanization is not concentrated, and the transportation of agricultural products does not need to be too long-distance, but today's highly concentrated urbanization can no longer meet the supply of vegetables only in the suburbs, and has to be transported from afar. However, if the storage resistance is not good, it is impossible to accomplish this task. The following is an introduction to the characteristics of storage resistance.

Tomato breeding

In the past, tomatoes will rot or crack after a little bump, which is very disadvantageous to long-distance transportation. in order to solve the characteristics of transportation and storage tolerance of tomatoes, breeding scientists improve the storage-tolerant quality of tomatoes from breeding materials. Of course, the effect of solving this trait through traditional breeding is still much worse, but it is not without effect. The quality of storage tolerance can be fixed by genetic improvement.

Later, scientists improved the characteristics of storage tolerance through transgenic methods. As you may not know, the first transgenic tomato in China was selected by Huazhong Agricultural University according to the characteristics of tomato storage tolerance. Of course, the effect of transgenic methods will be very fast, the effect is naturally very good, in terms of taste, there will be no change, transgenic is only for the characteristics of storage tolerance to do a genetic modification. However, at present, the commercial cultivation of genetically modified tomatoes has been cancelled, and there are no genetically modified tomatoes in China.

Collection and storage system

In the past, tomatoes were sold in the market after they were ripe, but now the situation has changed: they are harvested before they are ripe, and then ethephon ripens and then enters the market. The two processes do not seem to change much, but only one harvest after ripening and harvesting before ripening can make a big difference, including even if today's tomatoes are not resistant to storage, the storage quality of tomatoes is very high before harvest. Everyone has seen green tomatoes, when tomatoes can be stored for a long time, while ripe tomatoes can't last long no matter how much they are stored. Now, in order to facilitate tomato transportation, we have to adopt the method of harvesting before ripening and then ripening.

It is precisely because of the above two reasons that our current storage tolerance of tomatoes is much better, and it also enables urban residents to eat more tomatoes, otherwise it is a problem to transport tomatoes to the city. let alone meet the demand for tomatoes in the city. Tomato storage tolerance, we do not have to worry about harmful to the human body, it is completely superfluous.
