Image Credit: 123RF. Not all seeds sprout at the same rate. While environmental conditions may alter germination time (e.g., if the soil is too cold, tomato seeds may take longer to germinate ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
Germination is a process by which the seed develops into a seedling. The vital conditions necessary for this process are water, air, temperature, energy, viability and enzymes. If any of these conditions are absent, the process cannot undergo successfully.
Before the operation of a conventional seed drill, hard ground has to be plowed and harrowed to soften it enough to be able to get the seeds to the right depth and make a good "seedbed", providing the right mix of moisture, stability, space and air for seed germination and root development.
Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may have different characteristics from its parents. Some species produce seeds that require special conditions to germinate, such as cold treatment.
In the caryopsis, the thin fruit wall is fused to the seed coat. Therefore, the nutritious part of the grain is the seed and its endosperm. In some cases (e.g. wheat, rice) the endosperm is selectively retained in food processing (commonly called white flour), and the embryo and seed coat removed. The processed grain has a lower quality of ...
In botany, a plant shoot consists of any plant stem together with its appendages like leaves, lateral buds, flowering stems, and flower buds. [1] [2] The new growth from seed germination that grows upward is a shoot where leaves will develop.
Epigeal vs. hypogeal germination. Epigeal germination (Ancient Greek ἐπίγαιος [epígaios] 'above ground', from ἐπί [epí] 'on' and γῆ [gê] 'earth, ground') is a botanical term indicating that the germination of a plant takes place above the ground. An example of a plant with epigeal germination is the common bean (Phaseolus ...
