Why do carnations go to sleep in the city?
In 1908, a florist in Chicago, Wu, consulted a botanist. He said: "I have many beautiful pink flowers in the countryside, where they bloom very brightly, but in the city, they have developed sleep sickness." Botanists think it may be because the composition of the air in cities is different from that in the countryside. To prove his idea, he took a variety of gases in the glass cover, and then put the flowering pink inside, the results found. As long as the hood contains a few parts per million of ethylene gas, the blooming pink bamboo flowers will wither. It turned out that in the ship carrying the flowers, there was a leak of lighting gas. At the time, another physiologist knew about this, he put frogs in glass bottles, slowly added ethylene to do experiments, when ethylene added to four-fifths of the bottle, the frog finally fell asleep on the ground, but removed the frog, after a few minutes, it woke up. He then did numerous experiments on various animals, and ethylene made them sleep temporarily. Ethylene has since become an anesthetic used by surgeons to ease the pain of patients during surgery.

When there are 5 or 6 nodes on the main stem, the growing point of the stem tip can be removed, and more or less 1 or 2 nodes can be left according to the characteristics of the occurrence of lateral branches of different varieties.
