The strong winds of March 27 blew away days of haze, bringing a sunny afternoon to the Spring Observation Relay. The theme of this time is "The Distinction of Spring Flowers", the so-called spring flowers are the "standard flowers" of peach, plum, apricot, cherry, plum and begonia that people think of in spring.
In order to recognize flowers, professionals and readers also spelled. The above figure is a very scientific way of discernment, but is there a feeling that the brain turns and everything is finished? Would you take a picture like this and press it?

Can't tell the difference between these common flowers?
I don't blame you, because they are very much like each other!
If they are the flowers we are most familiar with, they may make many people scratch their heads. The number of petals is the same, the flower color from white to different degrees of pink, the size is not too much, just like the "ID photo" with a highly similar style, it looks different, but it is not clear where there is a difference. What is the difference between the spring flowers of our activities? The answer is that we start with fruit!
In front of eating, don't give in. Although the flowers are difficult to distinguish, the differences in the appearance and taste of the fruits are easier to penetrate people's hearts. Isn't it pleasant to enjoy the flowers under the warm spring sun while tasting the fruits under the spring flower trees?
From top to bottom, from left to right:
Plums, pears, peaches, begonias, apricots and cherries
Can you reverse the appearance of the flower according to the appearance of the fruit?
Then again, what does eating fruit have to do with identifying flowers? The mystery is hidden in the long spring flower identification flow chart in front of it. However, there is also a premise to keep in mind that if we lack basic understanding of the basic composition of flowers and the role of each part, then relying on eating fruits to distinguish these flowers can only be regarded as "white eating". At least we have to be clear that the ovary at the bottom of the pistil (peduncle) in the flower will develop fruitful seeds, so the number of flower peduncles represents how many seeds will be there when its fruit ripens.
The 5 seeds in the apple are properly cut, remember to cut horizontally. The apples we cut on the spot were really not beautiful enough.

Isn't that a bit of a sudden opening? Cut open the fruits and see how many seeds you can pick out, and then count the flowers nearest to you (but our discernment is limited to the most common flowers of peach, plum, apricot, cherry, pear and begonia, and simplicity is king).
After eating a good meal, look at it with the children, if it is you, how to classify these common fruits from the appearance? Say the basis for the classification.
If the way of counting the number of pistils in the flowers seems too specialized, then another perspective is to see if the fruit has a long stalk. The premise is that we must be very clear in our hearts that these fruits are grown from flowers, and the stem is the flower handle. Fruits with slender stalks such as apples, begonias, pears, and cherries must also have long stalks. On the contrary, the stalks of peaches and apricots are extremely short, and their flower stalks are also very short.
Short-stemmed peaches and apricots
Is this a step forward? First divide the fruit that is not easy to recognize into two groups according to the presence or absence of the stalk, so that at least the peach and apricot are first formed separately, and they represent the short-stemmed fruit. However, the plum is somewhat special, the stalk of the flower and fruit is long, but the fruit is ripe and the stalk is easy to fall off, so the plums we buy rarely see the residual stalk. The difference between peach and apricot flowers is the inconspicuous sepals, which cling to the petals and the apricot sepals fold downwards.

Isn't it like that?
Keep an eye out for apricot blossom sepals turning down.
The flowers of apples, begonias, cherries, pears, and plums are divided into long stem groups. Then recall whether the fruit in each group has multiple seeds or one seed, and compare it with the number of pistils. For example, an apple is generally 5 seeds, then its flower has 5 pistils; cherries have only one seed, natural flowers have only one pistil, and pears and apples have multiple seeds.

Begonia fruit we rarely eat directly, it is like a small apple, and apples are the same as apples, so it is no problem to think of them as one. There are many varieties of cherry blossoms, but not many can produce delicious fruits, but their flower structure is the same. The pear blossoms are white, and this feature is also quite obvious. But all three are proper long-stemmed fruits.
Plums and flowers, the flowers have obvious long stalks, but the finished fruit is rarely seen in the finished fruit.
The purple leaf plum commonly found in the park is a cultivated variety, not the variety we eat, but the flower structure is consistent.
Speaking of which, if you're still confused. Then delete the complexity and simplify, I hope this picture can bring you inspiration.
After talking about it for half a day, in fact, it is not as good as personally tasting in front of these plants and groping out your own set of methods. We encourage the habit of observation and perception, not the mere diffusion of knowledge. In the unknown, thinking in observation is an interesting process.
If you feel a lot of pressure to distinguish these "standard flowers", it is better to change your perspective and look at those strange flowers with us.
Populus is our most common willow plant, and May will usher in its flying seeds, annoying hairs.
Unlike the previous "standard flowers" or complete flowers, there are many plants whose flowers are unisexual flowers, such as the common woolly poplar or willow tree. In other words, each plant either has only male flowers or only female flowers. We did an interesting experiment, using blue paper pasted on the male plant of the hairy poplar, using red paper on the female of the hairy poplar, looking around, looking at the proportion of the male and female trees in the small forest in front of us.
This is the male flower of The Canadian Poplar (Canadian Poplar), and the more common Male Flower of the Woolly Poplar has completed the task of spreading pollen at this time, scattered and gloriously laid off.
We specially made a red and blue card to distinguish between male and female hairy poplars.
Although there are still many flowers that have not bloomed that day, it is only a matter of time, spring changes every day, may you not miss the wonderful journey of discovery.
