SOME RESULTS OF THE STUDY ON SIBERIAN FIR (ABIES SIBIRICA LEDEB) GROWN IN THE NURSERY OPEN FIELD AND GREENHOUSE
Keywords:humidity, heat, sapling, growth
AbstractThe present study aims to investigate growth dynamics of Siberian fir (Abies sibirica Ledeb) saplings and determine their development stages. Siberian fir seeds were planted in the open field and in the greenhouse at narrow-row spacing (10x5x15x5x15x5x15x5x15x5x10) with 1200 saplings selected as random samples. Climate of a given region is mainly affected by interrelated factors such as geographic location, ray of sunlight, atmospheric cycle and ground surface. Therefore, the study determines air temperature, precipitation, humidity, air heat and dynamics of saplings. The study also suggests that there are seven stages of growth of saplings and starting from the eighth stage, saplings reach 2 years old. Because this is the first study on growing Siberian firs directly from seeds in forest-steppe zone in Mongolia, it determines growth dynamics and development stages of 1-3 years old saplings and would serve as the basis for further studies on Siberian firs.
