Vol 2 Chapter 2117: This apple can only be seen but not eaten

We deserve that some fluorescent substances will cause harm to human health, and this luminous plant will not have this problem. Just when everyone was amazed at this fluorescent flower plant, Wu Hao raised a question that he was more concerned about.

Hearing this question, Yang Fang smiled and shook her head: "The fluorescent substance you mentioned is a radioactive element, which will naturally cause some harm to the human body. As for our luminous plant, it is a part of its own photosynthetic reaction. This phenomenon belongs to a kind of biological technology and will not cause harm to people. Not only that, normal smelling, touching and playing are fine.

However, we do not recommend eating and tasting, it may contain some plant toxins. Just like many flowers sold in flower shops, they are very beautiful in appearance, but they are poisonous. Just be careful with this, don't eat it by mistake. "

Wu Hao nodded slightly when he heard the words, that's fine, everything must be based on the premise of safety. Without security as a foundation, everything else is for nothing.

Seeing Wu Hao signaling to continue, Yang Fang swiped on the screen a few times, the lights turned on again, and the sunshade slowly unfolded. As for Yang Fang, he led the crowd to the next area.

There are mainly ornamental fruit plants grown in this area. Yang Fang pointed to a plant area full of fruits and introduced to the crowd with a smile.

Ornamental fruit? Many people in the crowd asked questions.

Yang Fangjian explained with a smile: "Yes, ornamental fruit, in fact, the origin of this ornamental fruit is very early, and it has been discovered and mentioned in some ancient maps and writings.

However, the earliest such ornamental fruits were mainly fruit trees, and they often appeared in the form of bonsai and garden sets, and their ornamental value was far greater than their edible value. However, at this time, these ornamental fruit plants mainly play an ornamental effect by cultivating ordinary fruit trees. Therefore, while viewing, it also takes into account the consumption.

In recent decades, there has been a fruit tree or fruit plant specially used for ornamental purposes, such as the kind of bonsai covered with red fruits, and some rich oranges, fortune oranges, etc. These things are no longer edible. , viewing is their only value.

And here we mainly cultivate these kinds of ornamental fruit plants, whose main function is to watch, of course, some of them may also take into account the role of food.

In our other glasshouse, we mainly cultivate these kinds of melons and fruits, and you can visit them later. "

Saying that, Yang Fang led them to an apple tree, and then smiled at the crowd and introduced: "This is an apple tree for viewing. The entire canopy is very beautiful, a bit like a Christmas tree, so Great for home growing.

The apples above are all ornamental fruits that we have carefully cultivated. "

While Yang Fang was talking, she also picked one from the tree, and then showed it to everyone: "Everyone, please see, this is the apple that bears on our apple tree. The fruit is about twelve centimeters in diameter.

The shape is very round, close to a circle, not the shape of an ordinary apple that is big on the top and small on the bottom. In addition to the round and beautiful shape of the fruit, the color of the apple is also very beautiful, showing a very bright red, and the red surface will have some gold stars.

As we all know, in order to make many apples look better, farmers need to intervene in the growing stage of apples, such as spraying ripening agents, or laying reflective aluminum foil to make the whole apples evenly colored and more beautiful.

And our apple doesn't need it, its own color is red, and normal planting management is enough. As time goes by, it will slowly turn from green to red.

In addition, its fruit shape is huge, so it is like a lantern hanging on the whole fruit tree, which is very beautiful. "

This apple is really big, but it looks a little light and not very moist. Zhang Jun weighed the huge round apple mentioned by Yang Fang and said involuntarily.

Yang Fang smiled and nodded and replied, "You're right, this kind of big apple is lighter than normal fruits and lacks water.

It's not a matter of managing the nurture, nor is it that we don't have enough water, it's that we nurture it on purpose.

Normally, an apple of such a size would weigh more than a pound, or even heavier. However, if the apple is too big and too heavy, the branches cannot bear the weight, so it will fall.

This may be normal for normal fruit trees. In general, the grower may also put a bag or something to prevent it from falling. But the ornamental fruit is not good, it is too ugly to do so.

And because the weight is too heavy, a branch can't bear a few on it, so the look and feel is not good.

In order to be able to hang more apples on the entire fruit tree, then we must lose weight on the apples. But the weight of an apple is related to its size. If the apple is too small due to weight loss, the ornamental value will also be greatly reduced.

So in order to meet these needs, we must make a fuss on fruit trees and apples.

First of all, we must change the relevant genes of the fruit tree to make its branches stronger and more resilient, able to bear more weight, hang more fruit, and not easily fall off.

Secondly, we have to change the internal structure of Apple to make it lighter.

As we all know, the factor that affects the weight of apples is the water content inside.

That's why the apples we just picked are very juicy, crisp and delicious. But the apples that have been placed for a long time are a little dry and waxy, and the weight will be reduced a lot.

Therefore, in order to reduce the weight of the apple, we need to transform the internal pulp without affecting the size, shape and color of the apple to reduce the water content, so that we can achieve the purpose of reducing the weight.

By editing the apple's genes, its pulp has a cotton-wool-like structure, which is not easy to store water, so that its weight can be greatly reduced.

In this way, we can achieve the purpose of hanging so many and such large apples on such a short and slender fruit tree. "

Hearing Yang Fang's introduction, Wu Hao took the huge apple and looked at it, then put it in front of his nose to smell it, and then asked Yang Fang, "So, this apple is no longer edible."

In fact, it is still edible, but the taste and taste may be a little worse. Yang Fang explained with a smile.
