Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

Chives are cultivated both for their culinary uses and for their ornamental value; the violet flowers are often used in ornamental dry bouquets. [29] Chives thrive in well-drained soil, rich in organic matter, with a pH of 6–7 and full sun. [30] They can be grown from seed and mature in summer, or early the following spring.
Garlic chives are also one of the main ingredients used with yi mein dishes. Its flowers are fermented to make garlic chive flower sauce (韭花酱). When the leaves of garlic chives are blanched by growing them in dark environments these are called jiǔhuáng (韭黄) or jiǔ cài huáng (韭菜黄), known in
Allium ochotense, or the Siberian onion, [3] is a primarily East Asian species of wild onion native to northern Japan, Korea, China, and the Russian Far East, as well as on Attu Island in Alaska.
Allium sacculiferum, also called northern plain chive [3] or triangular chive, [3] is an East Asian species of wild onion native to Japan, Korea, eastern Russia (Amur Oblast, Khabarovsk, Primorye), and northeastern China (Inner Mongolia, Heilongjiang, Jilin, Liaoning). [2] It is found along the banks of lakes and rivers at elevations less than ...
One example of Imbibition in nature is the absorption of water by hydrophilic colloids. Matrix potential contributes significantly to water in such substances. Dry seeds germinate in part by imbibition. Imbibition can also control circadian rhythms in Arabidopsis thaliana and (probably) other plants. The Amott test employs imbibition.
Allium senescens, commonly called aging chive, [4] German garlic, or broadleaf chives, [3] is a species of flowering plant in the genus Allium ...
