This is an Arabica coffee bean?! What are Polysperma multi-seed seven-seed coffee beans?

When you first saw the cover picture and the title, did you think you were joking? Isn't there only 1-2 coffee beans for one coffee fruit? That's what all the previous articles said!

Yes Indeed. According to the normal coffee fruit, a coffee fruit contains two coffee beans, which are the core part of the coffee fruit. Because the size of the fruit limits the space for the growth of coffee beans, so both coffee beans grow up face to face, so our common coffee beans are flat on one side and curved on the other, and such coffee beans are called flat beans.

But sometimes, coffee fruit is affected by insect pests, environment or genetic mutations during its growth, and eventually only one of the two coffee beans develops. Coffee beans that can develop also make room for their companions, and finally form an oval round bean (PB/ beads). In general, round beans are not likely to appear, and they are common in some coffee trees that have just reached fruiting age, accounting for 5-10% of the total tree yield.

When the code clerk first came into contact with the knowledge of coffee, he also thought that round beans were already very novel. ) until this year, when the code clerk peeled the coffee fruit harvested in front of his coffee shop by hand, and then carried out very small batches of honey-treated coffee beans, he found that there were three coffee beans in several coffee fruits. Beans are shaped like orange petals.

"em... After peeling, I wanted to take a picture. "

Perhaps it is because the code clerks forget to water every day and seldom apply fertilizer to loosen the soil, so that the quality of the fruit of a tree is not good enough. It may also be the unusual climate of Guangzhou, which makes the growing coffee fruit autistic. Or maybe there is a genetic mutation that makes coffee beans so "bossy".

There are 7 coffee beans in the coffee fruit on the cover of the article, which seems to be reasonable. After all, how could humans have expected that the plant itself had a genetic mutation? And than at least the three-peaked coffee beans in the hands of the word is random, this seven-petal coffee beans have been studied and cultivated by special researchers, and they also have their own name-Caf é Polysperma (multi-seed coffee), or seven-seed Arabica (Seven bean arabica).

As can be seen from the name, the multi-seed coffee variety carries the Arabica gene and belongs to the mutant variety of iron pickup. As for where it was first found, there seems to be no data to determine where it was found. According to the available information, multi-seed coffee was first recorded in 1890, but it may not be seven-seed, it may be more.

To be sure, seven-seed coffee trees were introduced and cultivated for research and protection by a joint project between the EPAMIG provenance bank in the Brazilian state of Minas Gerais and the Cerrado Mineiro Coffee producers Association.

Since 2005, more than 40 kinds of multi-seed genes have been introduced into the provenance bank for planting and research. According to some studies, multi-seed gene varieties of coffee, although the flavor is not good, but has a good resistance to leaf rust, so coffee planting research in other regions have also introduced multi-seed gene varieties for the improvement of coffee varieties.

"like a horse's hoof (water chestnut) growing on a tree!"

With such a large fruit, the flowers of multi-seed coffee trees are naturally different! As we can see from the picture, our common coffee flowers have 5 petals, while the petals of multi-seed coffee varieties are as many as 10! (Polyspermana)

According to the Caferium website, the flowers of these multi-seeded coffee trees produce a rose-like knot among the new leaves at the top of the tree. The calyx has more than 5 lobes, and the Corolla has two rings, each with 6-10 petals.

Such a big coffee fruit. What will it taste like? "how big is it?" (don't worry, I remember playing the comparison picture! Well, actually, I almost forgot!

If there are more coffee beans in a fruit, the nutrition will naturally be thinned, so the flavor of coffee is not ideal, so it is not planted in large quantities. However, the gene of resistance to leaf rust should be retained for genetic and genetic improvement.

"this is not garlic cloves! The size of multi-peeled coffee beans is also very big! "

Since it is not a perfect coffee variety, there are not many records about multi-seed coffee. This article can only let you know more about the cold knowledge of coffee and the mystery of nature.
