Drying starts at the bottom of the bin, which is the first place air contacts. The dry air is brought up by the fan through a layer of wet grain. Drying happens in a layer of 1 to 2 feet thick, which is called the drying zone. The drying zone moves from the bottom of the bin to the top, and when it reaches the highest layer, the grain is dry.
Cold stratification simulates the natural process by subjecting seed to a cool (ideally +1 to +3 °C [34 to 37 degrees Fahrenheit]) moist environment for a period one to three months. Seeds are placed in a medium such as vermiculite, peat, or sand and refrigerated in a plastic bag or sealed container. [1]

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.

Partially shelled popcorn seed saved for planting. In agriculture and gardening, seed saving (sometimes known as brown bagging) [1] is the practice of saving seeds or other reproductive material (e.g. tubers, scions, cuttings) from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees.

Marjoram (/ ˈ m ɑːr dʒ ər ə m /, [2] Origanum majorana) is a cold-sensitive perennial herb or undershrub with sweet pine and citrus flavours. In some Middle Eastern countries, marjoram is synonymous with oregano, and there the names sweet marjoram and knotted marjoram are used to distinguish it from other plants of the genus Origanum.
The Lamiaceae (/ ˌ l eɪ m i ˈ eɪ s i. iː,-ˌ aɪ / LAY-mee-AY-see-ee, -eye) [3] or Labiatae are a family of flowering plants commonly known as the mint, deadnettle, or sage family. . Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other ...
Recalcitrant seeds are seeds that do not survive drying and freezing during ex situ conservation. [1] By and large, these seeds cannot resist the effects of drying or temperatures less than 10 °C (50 °F); thus, they cannot be stored for long periods like orthodox seeds because they can lose their viability.
