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]
The leaves are used as a flavoring in a similar way to chives or scallions, and as a stir fry ingredient. They are often used in dumplings with eggs, shrimp, and/or pork. A Chinese flatbread similar to the scallion pancake may be made with garlic chives instead of scallions. Garlic chives are also one of the main ingredients used with yi mein ...
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.
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth. In the field of nutrition, the term signifies the practice of germinating seeds (for example, mung beans or sunflower seeds ) to be eaten raw or cooked ...
The hard stone restricts germination and cracking the shell or extraction of seeds hastens germination. Without pretreatment the seeds normally germinate within six weeks whereas extracted seeds only need one week to germinate. [citation needed] Seedlings to be used as rootstock can be raised from seed. Several studies indicate that germination ...
It is uncommon for pathogens to be transmitted from the plant to its seeds (in sexual reproduction or in apomixis), though there are occasions when it occurs. [2] [page needed] Seeds generated by apomixis are a means of asexual reproduction, involving the formation and dispersal of seeds that do not originate from the fertilization of the embryos.
It cannot tolerate the slightest frost or low temperature. Refrigeration of seeds at 4 to 13 °C (39 to 55 °F) resulted in loss of viability after 5 days. Seed germination is highly recalcitrant, reduced from 98 to 19% after 12 weeks of storage at room temperature; seeds stored for more than 137 days did not germinate.
A controlled fusion of the egg and sperm has already been achieved with poppy plants. [16] Pollen germination, pollen tube entry, and double fertilization processes have all been observed to proceed normally. In fact, this technique has already been used to obtain seeds in various flowering plants and was named “test-tube fertilization”. [17]
