PRESOWING TREATMENT OF SEEDS PINUS SYLVESTRIS VARIOUS STIMULANTS

Abstract

In the forest nursery of the Arykbalyk branch of the SNNP "Kokshetau" conducted monitoring of annual seedlings of common pine, which were grown from seeds using growth substances. In the nursery Arinbasarova branch of the SNNP "Kokshetau" we observed the one-year seedlings of pinussylvestris , which were grown from seeds with the use of growth substances. It was conducted by
soaking the seeds before planting in solution of the following stimulants: extrasol, EPIN-Ekstra, humate sodium humate + 7 minerals, zircon, "Baikal". Watering of seeds sown with soil activator AridGrow was carried out. It was revealed that the variants with soaking of Pinussylvestris seeds in extrasol for 5 minutes, humate+7 minerals for 2 and 6 hours and "Baikal" for 1 hour had the greatest energy of germination and laboratory germination. Laboratory germination of experimental variants was small and varied from 18 to 41%, it was 35% under control. All the experimental seedlings was superior in the height of control seedlings. The
survival rate of annual seedlings of Scots pine was large enough in variants with pre-sowing treatment of seeds "Baikal" for 30 minutes (97.6%), 1 hour (91.1%) and soaking in Na humate (2 hours) (90.0%). Only two options (when soaking pine seeds in extrasol for 5 minutes, in humate+7 minerals (2 hours)) lagged behind the control. As a result of the observations revealed a positive effect of presowing treatment of seeds pinussylvestris on survival and growth in height of annual seedlings pinussylvestris . In the North Kazakhstan region the best stimulants for seeds are "Baikal" with soaking for 30 minutes and 1 hour, as well as Na humate
with soaking duration of 2 hours, which is confirmed by the ranking analysis
