Scarification is a violation of the integrity of the upper shell of the seed.
For example, the seeds of sweet peas have a shell so dense and durable that water may not reach the embryo, but even if it penetrates inside, the sprout may not have the strength to break it. Therefore, it is recommended to scratch the surface of sweet pea seeds. How? It's very simple. Put the seed peas on a piece of sandpaper, cover with another piece of sandpaper on top, and, pressing with your hands, roll the peas, scratch. That's it! The scarification is done.
Another way. Soak the seeds in warm enough water. For sweet peas, a water temperature of about 60 degrees with an exposure time of up to six hours is suitable.
And if you find a recommendation to file the seed shell with a file or knife (usually, this is recommended for seeds of trees and shrubs), then you know - this is also scarification.
Despite the fact that these words are very similar, stratification is something else. It means pretreatment of seeds with cold. Sometimes short-term, sometimes quite long-term.
For example, what is very often called seed hardening is a short-term stratification.
Of course, you know that carrot, dill and parsley seeds should be soaked before planting and kept wet in the freezer of the refrigerator for at least three days. This is recommended in case the crops suddenly do not fall under slight frosts. Suddenly, spring will turn out to be so warm that the seeds will not receive their portion of cold, then they will germinate poorly.
And the seeds of perennial lavender, delphiniums, wild cherry, primroses, etc. need stratification lasting about a month. This scares many customers, although in fact everything is very simple.
These seeds can be planted immediately in the ground in late autumn. And don't even water it. Nature will do everything for us.
In general, for most perennials, winter planting is preferable to spring planting. Many annuals will also agree to this - asters, calendulas, marigolds, etc.
And if spring has already begun? It's nothing complicated either. Plant the seeds in a pot, pour them over and put them on the balcony if it's still cold outside. If it's warm, then put it in the refrigerator or in a cold cellar. For a month.
As you can see, it's nothing complicated.
Of course, these recommendations are not relevant for all Semenyans. As a rule, the bags indicate whether the seeds need stratification or scarification. オンライン カジノで 新規カジノ 入金不要ボーナス を獲得し、投資なしでギャンブルの世界への冒険を始めましょう。最も人気のあるスロット、ルーレット、テーブル ゲームをプレイして、リアルマネーを獲得するチャンスを掴みましょう。私たちのカジノは、自分のお金を投資することなく、運を試し、興奮を楽しむユニークな機会を提供します。
