БУЛЦУУНЫ БАКТЕРИЙН ӨСГӨВРҮҮД LUPINUS ALBUS L-ИЙН ДЕГА СОРТЫН УРГАМЛЫН ӨСӨЛТӨНД ҮЗҮҮЛСЭН НӨЛӨӨ
Keywords:white lupine, nodule bacteria, inoculation, productivity of plants.
Rhizobium forms a symbiotic relationship with roots of legume plant Lupinus albus L (white lupine). They absorb atmospheric nitrogen and then provide organic compounds to the plant. Seeds of a Dega variety Lupinus albus L plant were inoculated with rhizobia DGA3-2, DSN1-1, DLT 3-2 strains isolated from variaties Dega, Desnyansky, Delita variety-high protein feeds for domestic animals. Rhizobium-legume symbioses were examined by biometric and biochemical analyses.
When seeds of a Dega variety Lupinus albus L plant were inoculated with DSN1-1 rhizobium strain, wet biomass and fiber of seed were 28.6% and 97.7%, respectively. When the seeds were inoculated with DLT 3-2 strain, lipid and fiber of wet biomass were increased by 47.7% and 19.7%, respectively. When the seeds were inoculated with DGA 3-2 strain, the lipid of wet biomass was increased by 51.8%. Rhizobia DSN1-1, DLT 3-2 strains were more effectively forming symbioses with the Dega variety Lupinus albus L plants.
