After germination, transport plants to an area with a temperature of 60–70 °F (16–21 °C). Keep under light for at least 12 hours a day. Plant seeds 6 inches (15 centimetres) apart to prevent crowding. Remove deceased plants to promote growth for newly planted ones.
Before repotting seedlings, double-check your seed packets for planting instructions or do some research on the plant's growing needs. Seed packets will usually let you know if your seedlings need ...
Etiolation / iː t i ə ˈ l eɪ ʃ ən / is a process in flowering plants grown in partial or complete absence of light. [1] It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color . The development of seedlings in the dark is known as "skotomorphogenesis" and leads to etiolated seedlings.
The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule ...
These cultivated plants lack seed dormancy because of generations of selective pressure by plant breeders and gardeners that grew and kept plants that lacked dormancy. Seeds of some mangroves are viviparous and begin to germinate while still attached to the parent; they produce a large, heavy root, which allows the seed to penetrate into the ...
As the plant embryo grows at germination, it sends out a shoot called a radicle that becomes the primary root, and then penetrates down into the soil.After emergence of the radicle, the hypocotyl emerges and lifts the growing tip (usually including the seed coat) above the ground, bearing the embryonic leaves (called cotyledons), and the plumule that gives rise to the first true leaves.
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
A seedbed of rice plants. A seedbed or seedling bed is the local soil environment in which seeds are planted. Often, it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field.
