Abstract: Black locust ( Robinia preudoacacia) had introduced form north America for vegetation stability after landslides and forest fires, honey plant, etc. however, this species changes vegetation (plagiosere) with its high growth capacity and reproductive capacity. However, adult trees are easy to fall down after infection of root rot, and to regulate this alien species, native root rot fungi were used in Lithuania. Photosynthetic nitrogen (N) use characteristics of this species had been studying in situ at open and shade sites under larch plantations for regulation of the growth of this species. No seasonal change in N allocation pattern in leaves was found between open and shade site; N should allocate from N L (N in Light Harvesting Chloroplast) to N R (N in Rubisco) in a leaf after shedding of top canopy. To simulate increasing atmospheric CO2 [CO2], we studied on growth and evaluation of symbiotic microbe with black locust grown under a free air CO2 enrichment (FACE). Activities of acetylene reduction of nodule wereaccelerated in FACE (500 ppm). From these results, black locust will increase its growth rate under nutrient poor sites in increasing [CO 2] world, therefore, it is essential to develop the management methods which coexist with black locust.
