subject: Terms Vliyayushie On Seed Germination - Soaking And Quenching [print this page] Seeds of crops that provide seedlings for 12-20 days, soaked in water or various solutions that stimulate germination, on the day. Water during this time changed 3-4 times, the solutions do not change. In Kazakhstan, most soils is slightly alkaline or alkaline. They are poor in content available to plants of zinc, cobalt, and molybdenum.
The demand of vegetables in these elements is low and its largely be met by pre-treatment of seeds.
Solutions for soaking seeds prepared for snow, rain or boiled and ostuzhennoy to room temperature, normal tap water.

Processing time for bystroprorastayuschih crops (cabbage, radish) - 2-3, for the rest - 16-24 h. Here the concentration of certain solutions, proven in the context of Kazakhstan (in g / l of water):
aloe vera juice. Adults who have completed growth the leaves are cut, wrapped in dark cloth and maintained 10-15 days at 1-3 C, at the same time, they accumulate biogenic stimulators of growth. Squeeze the juice through cheesecloth and diluted with water at a ratio of 1:2.
Hardening of seeds
To increase the resistance of plants to cold, swollen seeds (mostly tomato, peppers, eggplant , cucumber) quenched variable temperatures. After etching and soaking the seeds are placed in a gauze bag, wrapped in a damp cloth and leave for a day in the room. Then within 6-15 days at 15-18 h they take out in a cold place, 6-9 h is made ??in house. During drying of seeds produced by the germination, increased drought tolerance of plants. Well dried, they do not lose germination when stored in a cool, dry place for 2-3 years.
Before sowing in hotbeds or greenhouses for seedling hardening continues until the germination of seeds, roots at the same time must not exceed 5 mm.
If for some reason, sprouted seeds sow at once is impossible, then they are stored for 2-3 days at 1-3 C. Sow them only in moist soil.
The most effective complex preparation of seeds for sowing , including sorting, treatment, soaking in a mixture of stimulating and quenching. After processing is necessary to check the germination of seeds. Seed treatment with low initial germination of the concentration of solution used is reduced by half and hardening do not spend.
