Soil microorganisms are essential for growth, emergence and development in all plants. In our study we decided to evaluate the effect that A. agilis UMCV2 rhizobacteria had on germination and growth of plants of economic-forest interest as P. devoniana to an age of 65 days. Our results show that the UMCV2 bacteria promoted growth of P. devoniana at this early stage of development, further highlighting that despite the short time of interaction between these two, the bacterium was able to increase the rate of germination, increase the size of shoot and generate a proliferation of lateral roots. The data shows a huge potential for using inoculum both in the greenhouse and in open ground and generate a growth promoting species of interest in both agricultural and forest, thereby reducing production periods depending on the crop.

Palabras llave : germination; Arthrobacter agilis UMCV2 and Pinus devoniana.
