Why hasn t a sand tomato been bred for thick skin, good transportation, and long storage life?

In fact, today's tomatoes are thick and easy to transport, but he is indeed not the kind of tomatoes of the past, so this variety is difficult to cultivate, fish and bear's paws can not have both, the tomatoes of the past are delicious, but it is not resistant to transportation and storage.

Until now, a habit and transport have not been cultivated, and it is rumored that the reason for the long hoarse tomatoes is that the pinyin of the tomato determines that his skin is not too thick, and in addition, the sand pulp determines that he is not very easy to transport and is easy to spoil.

Well, if you're looking for this, you're going to have a hard time cultivating, so you can use tissue culture -- it's a lot faster.

This friend, the current agricultural technology may not have cultivated this kind of tomato.

But tomatoes in some places may not be the same as tomatoes in others.

Because this kind of tomato is not suitable for you to grow in this place.

Now there is, now there are a large number of this kind of watermelon that is good to transport in the long batch of Hanhou, and the watermelons we have here are all transported from other provinces, aren't they all transported over long distances? You probably didn't go to the market to check it out.

Such tomatoes have a bad taste and are difficult to be recognized in the market, so experts do not breed such tomatoes.

Well, I don't think what you're talking about is very realistic, tomatoes with thick skin are not delicious, and even if they are easy to transport, um, the selling price will not be very high, so his um, the profit is not very high.

Although science and technology are very developed, there is still no way to cultivate a kind of melon and fruit that is easy to store and can be transported.

The cultivation of a variety requires a lot of experimentation and time to verify. At the moment there really is no such tomato.

Need research and technology to grow tomatoes, sand tomatoes can also be stored for a long date need to wait.

Everything you eat, after a while, it will rot and it will spoil, there is no need to develop the kind of thing you said, because there are enough things now, why develop this?

It shows that this thing is very difficult, because if the skin is too thick, it may not be very popular, and others don't like it.

Cultivating a plant requires long-term experimentation, because plants have a growth cycle.

So there needs to be a process.

That kind of estimation can't be eaten, food is food.

Scientists are working hard, and it takes time and effort to cultivate something.

I may not have figured out that method yet.

In the near future, technology will develop more and more, and this method will come out in the future.

It takes time to cultivate such tomatoes cheaply, and it also needs market recognition, not that they are cultivated, and it is useless if the market does not accept them.

Researchers are also working on this issue, but how can it be so easy? Maybe it will be successful in the future.

Because the senior brother must be ripe, he can be picked later, and the taste is poor, and it is not easy to store and transport after ripening.

The skin is not necessarily thick, but it tastes good. After all, it becomes something else and is not necessarily popular.

This is because it is not a very simple thing to grow such a tomato, and there are many factors to take into account, as well as its nutrition, so it has not been successful until now.

If it is not cultivated, it means that the technology is not yet at home. I'm sure we'll get better in the future.

You also have a lot of friends because of watermelons now, all of them are nearby elements, and he has a long-distance transportation situation, and he will be broken.

Now it is generally not, and it is not picked until it is fully ripe.

That is, seven or eight medium rare can be.

This is also convenient with transportation.

So there is no need to cultivate it.

Anything is possible, and it is possible to grow this sandy tomato in the future. Everything is the science of Uber is constantly evolving, and I believe you will.

At present, there is no hybridized heterogeneous skin that is easy to transport and can be stored for a long time.

There are a lot of red watermelons in the sandman now, and the skin is not too thin, so it is easy to transport.

Why hasn't a sandy soil with a thick skin that is well transported and stored long has not yet been cultivated? Watermelon tomatoes, in fact, this one. Mainly because of the current one-condition personality system.

Because now bred a kind of skin thickness is good, and the transportation is also stored for a long time. Sandy soil tomatoes. This is easy to cultivate, but the taste is not good, so it can't be accompanied.

Because this variety of tomatoes has a bad taste, and the benefits are not high, and the public does not like it, it is eliminated from the market.

Because the dish made by this kind of tomato stir-fry is not very beautiful, and the taste is not very good, many people do not like to eat this kind of tomato.

Because this variety also has a lot of difficulties when planting, and the adaptability is not very high, plus it is more expensive, it will be eliminated now.

(1) Make a hypothesis: Answer in the affirmative or negative to the question asked According to the question: Is the peel an indispensable protective tissue for the pulp? Make a hypothesis: the peel is an indispensable protective tissue for the pulp

3) Control experiment refers to the experiment carried out in addition to 4 different conditions when studying the influence of a condition on the research object, and the oral conditions are the same except for 4 different conditions The different conditions are the experimental variables Design principle: there can only be one experimental variable in an experiment, and its oral factors are in the same ideal state, so that it is convenient to exclude the possibility of affecting and interfering with the experimental results due to the existence of oral factors The variable of this experiment is the peel, so the method and steps:

A. One persimmon peels off the peel, B. The other persimmon is intact, and A and B form a control Observation phenomenon: A decays first

4) Conclude that the peel is an indispensable protective tissue of the pulp Therefore, the answer is: (1) the peel is an indispensable protective tissue of the pulp (3) peel off the peel; Intact; aFirst rot;

4) The peel is an indispensable protective tissue for the pulp
