Shanks, coddled, absolutely unadapted to conditions of the open ground, take root badly. Therefore before disembarkation they need to be tempered. This procedure helps shanks to adapt better in adverse conditions and increases their stability.
Even at the beginning of summer frosts are possible at night. That shanks well took root, use agroreception – hardening. It usually there begin weeks for two before disembarkation to the open ground.
During training, conditions the closest to natural in which the plant should grow are created. During training at shanks for several days growth of escapes stops. Leaves and stalk gain saturated green color.
Light training takes place at temperature from +15 to +25os. After it in escapes the maintenance of pigments increases almost five times. And on heel of shank which was in nutritious solution pronounced root hillocks are formed. After light training the gap between root - and forthputting is almost absolutely liquidated. And rooting of shanks in shkolka is the main key to high exit of saplings. Training time – 10-15 days. In the beginning it should be seen off only in morning and evening hours and it is obligatory to bring for the night to the warm room. The last 5-6 days should be done training under direct sunshine and to leave shanks on the street even at night. To the room they should be brought only at frosts. Excellent results are yielded by training under the film shelter. It is carried out under direct sunlight. The first 6-8 days it is necessary to protect gain from overheating and especially bright sun. For this purpose it is necessary to raise film and to regulate temperature. To watch that it was not lower than +10 and not above +25os. If there occurs temporary fall of temperature to +5os, shanks should not be brought to the room. Even during cold snap the leaflets continue to produce organic matter and to assimilate partially. And at threat of frosts the film covering needs to be warmed blankets.
