Chapter 2117 This kind of apple can only be looked at but not eaten
【Revision】
"We know that some fluorescent substances can cause harm to human health. This kind of luminous plant will also have such problems." When everyone was amazed by this fluorescent flower plant, Wu Hao proposed a comparison.
issue concerned.
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 plants, it is a kind of its own photosynthetic reaction.
The phenomenon is a kind of biotechnology and will not cause harm to people. Not only that, normal smelling, touching, and playing will be fine.
However, we do not recommend eating it, as 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 pay attention to this and don't eat it by mistake."
Wu Hao nodded slightly when he heard this. That's fine. Everything must be built on the premise of safety. Without safety as the foundation, everything else is in vain.
Seeing Wu Hao's signal to continue, Yang Fang slid on the screen a few times, the lights came back on, and the sunshades slowly opened. Yang Fang, on the other hand, led everyone to the next area.
"This area is mainly planted with some ornamental fruit plants." Yang Fang pointed to a plant area full of fruits and introduced it with a smile at everyone.
"Ornamental fruits?" Many people in the crowd asked.
Yang Fang Jianzhang smiled and explained: "Yes, ornamental fruits. In fact, the origin of this kind of ornamental fruit is very early. It has been discovered and mentioned in some ancient atlases and writings.
However, the earliest such ornamental fruits were mainly fruit trees, and often appeared in the form of bonsais and garden scenery. Their ornamental value was far greater than their edible value. However, at this time, these ornamental fruit plants were mainly
Ordinary fruit trees are cultivated to achieve ornamental effects. Therefore, while ornamental, they are also edible.
In recent decades, a kind of fruit tree or fruit plant has appeared specifically for ornamental purposes, such as bonsais full of red fruits, and some fortune oranges, fortune oranges, etc. These things are no longer edible.
, appreciation is their only value.
As for us, we mainly cultivate these types of ornamental fruit plants. Their main function is to watch them. Of course, some of them may also be used for food.
In our other glass greenhouse, we mainly cultivate this kind of melons and fruits, and you can visit it soon."
With that said, Yang Fang led them to an apple tree, and then introduced with a smile to everyone: "This is an apple tree for viewing. The whole crown is very beautiful, a bit like a Christmas tree, so
Very suitable for home cultivation.
The apples above are all ornamental fruits that we have carefully cultivated."
While Yang Fang was talking, she also picked one from the tree, then showed it to everyone and said: "Please see, this is the apple on our apple tree. The whole apple is relatively huge in shape and is a large-scale apple."
The fruits are all over twelve centimeters in diameter.
The shape is very round, close to a circle, rather than the fruit shape of ordinary apples with a big top and a small bottom. In addition to the round and beautiful fruit shape, the color of the apple is also very beautiful, showing a very bright red color, and the red surface
There will be some gold stars.
As we all know, in order to make the apples look better, farmers need to intervene during the growth stage of the apples. For example, spraying ripening chemicals or laying reflective aluminum foil can make the entire apple color evenly and look better.
But our kind of apple does not need it. Its natural color is red, and normal planting and management are enough. As time passes, it will slowly change from its original green to red.
In addition, its fruit shape is huge, so it looks like a lantern hanging on the entire fruit tree, which is very beautiful.”
"This apple is really big, but it looks a little light and doesn't have enough water." Zhang Jun couldn't help but said after weighing the huge, round apple that Yang Fang mentioned.
Yang Fang smiled and nodded and replied: "You are right, this kind of big apple is lighter in weight and lacks water compared to normal fruits.
This is not a problem of management and cultivation, nor is it that we have not paid enough attention, but that we have cultivated it this way deliberately.
Normally, an apple of such a large size weighs more than a pound, or even more. But if the apple is too big, if it is too heavy, the branches cannot bear the weight, so it will fall.
This may be normal for normal fruit trees. Generally speaking, fruit farmers may also put a bag or something to prevent it from falling. But this is not true for ornamental fruits. It is too ugly to do so.
And because if the weight is too heavy, one branch cannot bear several of them, so the appearance is not good.
In order to be able to hang more apples on the entire fruit tree, we must reduce the weight of the apples. But the weight of the apples is related to their size, because if the apples are too small due to weight loss, their ornamental value will also be greatly reduced.
So in order to meet these needs, we must make a fuss about 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, bear more fruits, and not fall off easily.
Secondly, we need to change the internal structure of the apple to make it lighter.
As we all know, the factor that affects the weight of an apple is the moisture content inside it. The higher the moisture content, the heavier the weight, and vice versa.
This is why the apples we just picked are very juicy and full, very crisp and delicious. But the apples that have been stored for a long time are dry, pink and waxy, and their weight will also lose a lot.
Therefore, in order to reduce the weight of apples, we need to modify the internal pulp without affecting the size, appearance and color of the apples to reduce the water content. In this way, we can achieve the purpose of reducing weight.
We have edited the apple's genes so that its pulp has a cotton-wool-like structure that is less likely to retain water. In this way, its weight can be significantly reduced.
In this way, we can achieve the goal of hanging so many big apples on such a short and slender fruit tree."
After hearing Yang Fang's introduction, Wu Hao took the huge apple and looked at it, then put it in front of his nose and smelled it, then asked Yang Fang: "So, this kind of apple can only be seen but not eaten.
"
"Actually, it's still edible, but the texture and taste may be a little worse." Yang Fang explained with a smile.
Speaking of this, Yang Fang said with a smile: "We have big apples specially bred for consumption over there. They are about the same size as this and taste very good. You can taste them later."
