In the process of observing the growth and development of the flowers to the fruits and seeds of the plane tree, because I was too anxious, I caused a crack of about 10 days between the insemination of the female flower, the beginning of the development of the ovary and the opening of the five small butterfly fruits like fingers, and now, this crack has been filled.
See, some of the tops of the bean fruit below (of course, it cannot be called "fruit" at this time, let's call it) are still gathered together, like the skeleton of a lantern; Some tops have been separated, like mechanical claws. Of course, we also obviously see very clearly that not all female flowers are lucky enough to be pollinated and insecuted and grow and develop normally.
Do the math, only 12 days have passed since the last observation. In the last article, I really didn't expect the 5 brothers to separate so quickly. Actually, think about it, after all, they should crack by late July.
Remove a small lotus fruit – I'll call it "heartskin", carefully cut along its ventral suture with a knife, and I was surprised to find that there were 2 small white dots on each side of the edge of the pericardium - ovules! It is clear that they originally grew staggered, not originally symmetrical and then staggered by the force of the heart's skin.
I am glad that my previous explanation of this in the comments of the article was wrong, it was just my self-righteous subjective imagination, and this time I finally got the correct explanation through observation - although the result was the same. Plants are far smarter than we think, they know how to do it, and far-fetched explanations only make themselves seem so naïve and ridiculous.
It should be noted that whether it is very small or when it is about to crack in late July, when you cut it, there will always be a lot of brown and slightly sticky liquid, and you must be prepared in advance, otherwise you will be a little embarrassed.
At this point, I have nothing more to say about the flowers, fruits and seeds of the plane tree for the time being.
