The timing of germination of different plants
A variety of flora, each plant its own characteristics and different periods of germination. Vegetable crops grown in Russia, have variation in the timing of germination from 3 to 20 days. Quickly germinate Cruciferae – the radishes, the cabbage, radish. Under favorable conditions, they come to the surface after 4-5 days.
Tomatoes, pumpkins, squashes germinate in 4-7 days. A little longer sit to the ground beets, carrots, eggplant, peppers – 8 to 15 days. When planting is necessary to consider that the Solanaceae – and thermophilic, at low temperatures, below +20 ° C, time of germination increased up to 20-25 days. Tight, within a month, germinate celery and parsley. At high temperature and adequate moisture, the germination of watermelon appear in 6-7 days after planting, and melons – 3-5 days.
Flower seeds, as well as the vegetables have different times of germination, most of the boards in 1-2 weeks. The zinnias, gillyflowers, marigolds will take 2-8 days, vervain sprouts hatch in 15-22 days. Unlike annuals, perennial crops have significant periods of germination, for example, some species of irises and lilies on the germination takes months.
Affects the timing of crop emergence temperature. Aliens from a cold climate to germinate in 6−10 ° C, for southerners optimal temperature 10-12 ° C, seeds of tropical crops need to be 20−30oC.
How to stimulate the growth of the seeds
Accelerate the germination of seeds of natural stimulants:
− aloe juice;
− succinic acid;
chicken egg;
− ash water.
The easiest way to stimulate the seed to hold it 6-8 hours in a solution of "Energen": 5 drops to 1 Cup of water.
To reduce the time of germination can, soaking the seeds before planting in a moist environment wrapped in wet cotton cloth and put in a container. Germination is preceded by swelling, the seed absorbed water and returning to life. As soon as the seeds hatch, they immediately planted in soil. Do it cautiously, trying not to damage the fragile sprout.
Depends on the germination rate and planting depth. Small seeds for germination need light, so they only lightly sprinkle the ground. Some seeds require stratification – maintaining them at low temperature for 1-2 months.
Moisture and cold lead to the growth of the embryo, softening and cracking of the shell. Landing product in rigid sheath for quick germination is subjected to scarification, that is, destroy the top layer of propilivanie or perforation.
