METHOD OF PRE-SOWING TREATMENT OF LARCH SEEDS FOR ACCELERATION AND INCREASE GERMINATION IN PROCESS

摘要

FIELD: agriculture.;SUBSTANCE: invention can be used in growing of larch seedlings in greenhouses. Moist seeds are held under snow and dried to loose state. Prior to stratification seeds are treated by tetramethylthiuram disulphide TMTD in amount of 4.0 g per 1 kg of seeds. After drying, they are packed into canvas bags with a layer of not more than 2 cm. It is held before sowing for two months. Immediately before sowing, the seeds are soaked in potassium permanganate 0.2 % for 10–15 minutes for pickling against fungal diseases. Then one performs soaking for 3 hours in a solution of Biopreparat Zircon. Then the seeds are dried and sown.;EFFECT: enabling acceleration and increase in the percentage of emergence and energy of germination of seeds, which affects the rate of obtaining standard planting material.;1 cl
