On 22th August, Professor Andrea Polle at forestry institute of the Gottingen University came to make academic exchanges and reported on“Molecular, Physiological and Growth Acclimation of Trees to Phosphorus Stress”at the invitation of Lab of forestry cultivation of Experimental Center of Forestry in North China. The Lab was aimed to have a better understanding of impacts of nutrient stress on the growth of forest, eventually progress the relevant researches at the Center.
During the report, Professor Andrea Polle detailed the distribution of Phosphorus elements in the global forests and the their constantly rising trends in recent years. He mainly revealed the strategies to response and trade-off mechanism for plants under the phosphorus stress through the limitation to phosphorus elements and long-term positioning and observation of contents, utilization rate and cyclical features of phosphorus elements in different types of plants under phosphorus enrichment conditions. He also pointed out that ectotrophic mycorrhiza plays the key role in the utilization of phosphorus elements and we can sift out key elements that controls utilization of phosphorus elements through 3PP tracer thchniques and molecular biological means.
Zhang Yao, director of the center expressed the gratitude to Professor Polle for his fabulous report and guidance to groups of scientific research at the center. He pointed out the groups should take full advantage of the functions and strengths of national forestry experimental base for scientific research on basis of its own development and mission, actively participate in cooperation and exchanges at home and abroad, broaden its horizon and inspire more ideas for scientific researches so as to contribute to the forestry development in North China and the rest of the world.
More than present researchers actively submit their questions and make cooperation and discussions with Professor Polle on the relevant researches carried out and key technologies and key scientific issues.
Ph.D Andrea Polle is the board member of Gottingen University, professor and director of research institute of forest botany and prestigious scientists in international tree Psychology, ecology and botany. He main studies includes the study on the stress resistance of trees(drought resistant, salt resistant and heavy metal-resistant.), trees ecological research and timber forming ,
plant-mycorrhiza interaction mechanism and the diversity of Mycorrhiza functions.
