Der für den 30. September geplante Vortrag der P-Campus-Ringvorlesung 2021 von Yue Hu (Leibniz-Institut für Pflanzengenetik und Kulturpflanzenforschung (IPK)) zum Thema "P utilisation capacity of forage legumes from recycling products" wird auf den 25. November verschoben.
Alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) are important forage legumes cultivated around the world. Phosphorus (P) plays an important role in their growth, therefore P fertilisers are usually applied during their cultivation. However, the interspecific and intraspecific P efficiency of alfalfa and red clover to utilise P from different fertilisers are less well studied. A field trial and a pot experiment were conducted at the University of Rostock, North-Eastern Germany, to test the P efficiency of eight selected accessions each of alfalfa and red clover in utilising P from different sources. This lecture is based on these two experiments and will introduce some basic knowledge of alfalfa and red clover, background of P recycling products, as well as available results from the two experiments regarding plant P uptake and P efficiency of both species.
