Seeds of hybrid varieties F1
When purchasing bags of commercial seed is now common to find the bag that name beside the name of the variety. The commercial hybrid seeds are not something modern, have existed for many years, and even have something negative in itself.
This feature primarily indicates two things: that the plant comes from the intersection of two genetic lines as well, and that will give a very similar product such as shape, height, weight, and flavor. Surely also indicates that the seed that will produce another hybrid seed, and this time not as uniform.
If you are, in fact, riseminano of seed harvested from a tomato or a hybrid melon F1, for example, plants that grow, this time F2 hybrids, i.e., another subsidiary, will in most cases different from one another and perhaps not so productive as the mother plant.
That’s why it is usually not recommended to re-seed hybrids. Instead, it is wrong to feel the seeds of combinations are not germinating: they are the equal of other non-hybrid, could not own more than all food and productive characteristics of their variety.
Open-pollinated varieties Seeds
They are instead the opposite of hybrids, namely that the seeds collected from these varieties are genetically stable and retain all the production characteristics of the parent plants and therefore are riseminabili. They are usually too old traditional varieties and are much cheaper because of the hybrid seeds easier to grow.
The old varieties have the advantage of not having been subject to modern techniques of genetic modification, preserve traditional flavors, are often better suited to amateur crops because they do not have those useful features instead of the mechanized harvesting system for cold storage of large retail chains. And allow you to cultivate as if the seeds for their consumption.
The best container to store them
The seeds often have to stand the test of time, live, and be stored for years before being disseminated. What is their best container that protects them in this retention period? It may seem strange, but the materials that help conservation are certainly the more simple: small paper bags, in turn, contained in glass jars sealed.
The important thing is that the bags are well drilled and not disperse seeds.
How to avoid the worms? Mix the seeds a little calcined diatomaceous earth, which acts both as a desiccant and as a natural insecticide.
And if you have room in the refrigerator, not freezer below freezing that would kill them, you can use it to store glass jars. This will significantly lengthen the life of our seeds.
There are seeds that, once collected, are not immediately ready to be disseminated. This is the case of some aromatic plants, such as sage or lavender, or wild seeds like most of those native trees whose seed does not germinate if they have not been a few months of collection.
To speed up this process of awakening is enough to put them in the refrigerator and leave them for a few weeks. After germination becomes normal, the same heat treatment can work to speed up the germination of some seeds abortive lenses: you leave them some time before sowing them in the refrigerator in the ground or seedbeds, and you get prompt and uniform germination.
Some seeds are not pure seeds at rest, but real living shoots. And the case of Roscano, that instead of the seed produces in effect a small bud, or chayote, which is a substantial seed inside the fruit and that cannot be separated from it without devitalizzare.
The life of these seeds is usually a few months from the time of separation from the mother plant.
Freezer for vegetables and
Did you ever put in jars of pea or chickpeas and find a few months later a small troop of blacks insettini, the weevils, that if you are eating them from the inside? Unfortunately, these insects are small beetles that are born from eggs laid when our pulses were still on the plant.
To defeat, just put legumes for some time in the freezer at -20 ° once dried and collected.
The seeds of legumes, unlike smaller seeds, do not get ruined by freezing. Even the cold kills any type of parasite that can contain and will prevent their eggs from hatching — a simple and effective way to combat a common parasite of all legumes.
