In home gardens, for example, the seeds of plants which are otherwise difficult to grow from seed may be made viable through scarification. The thawing and freezing of water, fire and smoke and chemical reactions in nature are what allow seeds to germinate but the process can be sped up by using the various methods described thus far.
Typically, these create an environment in which light, humidity and temperature are controlled to provide optimum conditions for the germination of seeds. One type of germinator is the Copenhagen or Jacobsen tank. The seeds rest upon blotting paper which is kept moist by wicks which draw from a bath of water whose temperature is regulated. The ...
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 ...
Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [3] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural form of "cold ...
Rubus parviflorus is a dense shrub up to 2.5 meters (8 feet) tall with canes no more than 1.5 centimeters (1 ⁄ 2 inch) in diameter, often growing in large clumps which spread through the plant's underground rhizome.
The mulberry plants allowed to grow tall have a crown height of 1.5 to 1.8 m (5 to 6 ft) from ground level and a stem girth of 10–13 cm (4–5 in). They are specially raised with the help of well-grown saplings 8–10 months old of any of the varieties recommended for rainfed areas like S-13 (for red loamy soil) or S-34 (black cotton soil ...
Mulberry can be grown up to 4,000 m (13,000 ft) above sea level. Mulberry blooms well in warm, rich, fertile, well-drained, loamy to clayey soils, porous with strong moisture-holding ability. The optimal soil pH range is 6.2–6.8. Because mulberry is a hardy crop, the soil moisture can be used to a greater extent by these plants.
One example of Imbibition in nature is the absorption of water by hydrophilic colloids. Matrix potential contributes significantly to water in such substances. Dry seeds germinate in part by imbibition. Imbibition can also control circadian rhythms in Arabidopsis thaliana and (probably) other plants. The Amott test employs imbibition.
