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. [9]
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.
Dormancy should not be confused with seed coat dormancy, external dormancy, or hardheadedness, which is caused by the presence of a hard seed covering or seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol ...
Ajwain or ajowan (Trachyspermum ammi) [3] (/ ˈ æ dʒ ə w ɒ n /) —also known as ajowan caraway, thymol seeds, bishop's weed, or carom—is an annual herb in the family Apiaceae. [4] Both the leaves and the seed ‑like fruit (often mistakenly called seeds) of the plant are consumed by humans.
Abscisic acid is also produced in the roots in response to decreased soil water potential (which is associated with dry soil) and other situations in which the plant may be under stress. ABA then translocates to the leaves, where it rapidly alters the osmotic potential of stomatal guard cells , causing them to shrink and stomata to close.
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.
Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. [1] Vegetative reproduction involves a vegetative piece of the original plant producing new individuals by budding, tillering, etc. and is distinguished from apomixis, which is a replacement of sexual reproduction, and in some cases involves ...
Origanum dictamnus, the dittany of Crete, Cretan dittany or hop marjoram, is a tender perennial plant that grows 20–30 cm high. It is known in Greek as δίκταμο ( díktamo , cf. " dittany ") or in the Cretan dialect as έρωντας ( erontas , "love").
