Tips for housewives.

I am not a rich person, and therefore I buy ahead of time during sales with the expectation of a certain period.

For example, the same grapes.

But, HOW to keep it fresh for a few weeks or even a month?

It just dries and wilts in the refrigerator.

It bursts in the freezer and turns into porridge, losing both taste and smell.

I tried to put it in tubs of water. Lasts longer, but begins to mold and rot.

I came up with an idea: I put the bunch in a plastic box or on a tray and put a repeatedly folded soaked paper napkin on the stem. This supplied the bunch with moisture and preserved the turgor of the grapes. But the water was drying up and I didn’t always notice it in time.

More honestly— OFTEN!

In parallel, I conducted the following experiments:

I put a bunch of grapes empty in a jar of water and looked to see if this bunch, empty of grapes, would grow roots.

She didn’t let me in, but she just dried up normally.

But the last couple of times something interesting happened: When I picked the berries on a twig, sometimes there was some part of the grape left – a thin green rod. He put an empty bunch in a jar of water. And then I discovered that this part, the GREEN one, remained GREEN for many weeks, even more than a month!!!

This means that the water pump CONTINUED TO WORK even in the grapes that had been cut off and had been without water for a long time, supplying these green rods with water!!! Otherwise, they would have dried up in a few days too.

And now, having bought grapes once again, I placed the bunch in a wide funnel with a hole at the bottom and put this funnel in a bowl of water so that ONLY the stem was immersed in water. I think this is a possible solution to the storage problem.

Of course, such a “construction” is not mandatory! Any variant of the “device” that provides the STEM with water all the time, while the bunch itself is not immersed in water, can be a good solution!

Let’s see!

It is clear that the stalk is capable of supplying water to twigs with berries! Similar to cut flowers in a vase with water.

Apparently, the berry cells send “humoral” signals to the “muscles” of the pump, which supply water to the berries by a kind of “peristalsis”, thereby stimulating their activity. THAT’s WHY the green rods lived so long! They were the ones who, being part of the grapes, produced “peristalsis” stimulants in the cuttings and twigs on which they hung, and thus preserved their lives, so the empty twigs of the bunch, on which there was nothing left, dried up quite quickly after the grapes were cut off.

But why did these green rods wither anyway? For the same reason. Why do cut flowers wither? Water is an important component for plant life, but it DOES NOT REPLACE REAL plant juice, which contains dozens of different substances necessary for the existence of a flower or fruit! Just as injecting saline solution (water with 0.75% sodium chloride) into a person can raise the total blood pressure (in case of massive blood loss, but this will not ensure the long-term life of an organism in need of gas exchange, glucose and many other substances and shaped blood elements.

I think that the peristalsis of both blood vessels and intestines in animals is “borrowed” from our plant predecessors!
