THE PROLONGED INFLUENCE OF ROOT DRESSING OF CAJANDER LARCH (LARIX CAJANDERY MAYR.) ANNUAL AND BIENNIAL SEEDLINGS WITH THE GROWTH STIMULANTS ZIRCON AND EPIN ON THEIR GROWTH AT FIFTEEN YEARS OF AGE
Cajander larch (Larix cajandery Mayr.) is the eastern race of Gmelin larch, the main forest-forming species in the Amur Region and the Primorsky Territory. It is widely used in the national economy. It is promising for landscaping. However, as a result of improper felling and forest fires, the area...

Cajander larch (Larix cajandery Mayr.) is the eastern race of Gmelin larch, the main forest-forming species in the Amur Region and the Primorsky Territory. It is widely used in the national economy. It is promising for landscaping. However, as a result of improper felling and forest fires, the area and stocks of larch have been significantly reduced. Its accelerated artificial restoration is necessary. One of the ways to solve this problem is the use of growth stimulants. The aim of the research was to study the stimulating effect of aqueous solutions of growth stimulants Zircon and Epin at various concentrations of solutions on biometric indicators of annual seedlings and mature Cajander larch trees at the age of 15. In the spring of 2009, grown larch seedlings were transplanted into the previously prepared soil of school department of the nursery with the placement of 0.5 × 0.6 m. During the growing season they were fed twice with Zircon and Epin in concentrations of 0.01 and 0.001%. Seedlings that were not subjected to any treatment were taken as a control sample.
