The difference between Toona sinensis and Ailanthus altissima, as the saying goes: "There is Toona sinensis in front of the house, and spring vegetables are always there." Although Toona sinensis is good, there is always Toona sinensis sorrow. What are the real Toona sinensis mixed with fish beads in the vegetable market? Let's take a look at the difference between Toona sinensis and Ailanthus altissima.
The difference between Toona sinensis and Ailanthus altissima 1 Before and after Tomb-Sweeping Day, Toona sinensis trees began to sprout, just pouring into the early spring market. There are two kinds of Chinese toon heads, and the taste of green buds is better, which is what we often eat; Red buds are rough and the aroma is not very good. How can we ensure that the Toona sinensis we bought is not Ailanthus altissima? In fact, it is not difficult. By observing the appearance of leaves, you can easily distinguish Toona sinensis from Ailanthus altissima. Judging from the appearance of Toona sinensis, the root is light green, the leaves on each branch are even, and the leaves on each branch are odd, which is definitely not a Toona sinensis tree. On the other hand, we can also distinguish them by smell. You can rub a leaf with your hand and put it in front of your nose to smell it.
Generally speaking, around the Toona sinensis, there is often a kind of plant with a strange smell, which is called Ailanthus altissima by the people. It really wants to be associated with Toona sinensis, but its strange smell makes people know it thousands of miles away. However, in order to earn more profits, some merchants cheat consumers and sell Ailanthus altissima as Toona sinensis. If someone can't tell the difference between the two, buying it home will definitely make people sick and uncomfortable. Although they are similar in appearance, they are quite different in nature. The reason for the similarity is that they are all perennial trees, but they belong to different families.
In a very distant era, Toona sinensis is called the best wood, and they often use it as the raw material of wood products. This is because it is tall and straight and its texture is hard. The plants of Ailanthus altissima will be short, grow irregularly, and the trunk will be rough and not hard enough for people to use.
It is recorded in ancient literature that one day, Zhuangzi passed by Ailanthus altissima and said, "I have a big tree, which people call a dead tree. Its big book is bloated, the twigs are curly and unruly, and the craftsmen ignore it ... "Finally, he said, smelling it with his nose. If it is fragrant, it is Ailanthus altissima; If it is strange, it is Ailanthus altissima.
The difference between Toona sinensis and Ailanthus altissima II. First, the smell is different.
You can tell from the name that one is fragrant and the other is smelly. Toona sinensis contains volatile aromatic organic compounds such as toosendanin, which smells very refreshing, while Toona sinensis is a strange smell similar to bedbugs and grass. Just twist the leaves by hand and smell the smell when you buy them.
Second, the blade is different.
1. Although they all have pinnate compound leaves, Toona sinensis generally has even pinnate compound leaves and Ailanthus altissima has odd pinnate compound leaves. As long as the leaves are paired and even, it is basically a Toona sinensis tree.
2. Toona sinensis leaves are yellowish brown at the tip, light green at the root and dark green at the leaves of Ailanthus altissima.
3. The leaves of Ailanthus altissima have swollen glandular spots near the bottom of the base, and there are glandular spots on the back of the leaves, which is the root of odor release; Toona sinensis leaves are not available.
4. Toona sinensis leaves are full-prismatic, and the upper part of Ailanthus altissima leaves is full-prismatic, with sparse serrations near the lower edge, generally two to four thick serrations, and each serration has glandular points on the back, which is also a sign to distinguish Toona sinensis from Ailanthus altissima leaves.
Third, fruits are different.
Although the shapes of Toona sinensis and Ailanthus altissima are very similar, they can still be distinguished very well after flowering and fruiting. Toona sinensis belongs to Meliaceae, which has a round capsule that will crack when it matures. Ailanthus altissima belongs to Araliaceae, with flowers like cones and fruits like tiles covering arranged samara, which will float away when the wind blows.
Fourth, the trunk is different.
The trunk surface of Ailanthus altissima is smooth and does not crack. The trunk of Ailanthus altissima is straight, the tree body is rough, and it often peels off in pieces and has cracks.
Toona sinensis is also called "the vegetable on the tree". As early as the Han Dynasty, people in China spread the way of eating Toona sinensis all over the country, but it was really inedible. According to medical literature, Toona sinensis is "slightly toxic", which is only used for external washing of decoction, so it is not only because of its bad smell, but also has certain toxicity, so it must be clearly distinguished when buying and picking Toona sinensis buds.
