Lolium perenne (L.) is one of the most used turfgrass species for the establishment of

multipurpose turfgrass both in Turkey and around the world. Lolium perenne (L.) is sensitive

to environmental abiotic stress conditions such as drought and salinity. This study aims to

improve the germination properties of Lolium perenne (L.) seeds (turf varieties of Sun and

Ringle) under drought stress. The seeds of Sun and Ringle were covered with the seed coating

solution, included Endomycorrhiza, Trichoderma spp., Bacillus subtilis, Bacillus megaterium. -1

The coating solution was applied 4 liters 1000 kg seeds . This germination experiment was conducted in randomized parcel design with 4 replications. A total 6 different drought stress levels (0, -2, -4, -6, -8, -9.8 Mpa) were created in this study and used Polyethylene glycol-6000 (PEG-6000). 20 seeds were laid in each petri dish and placed in the germination cabinet (70% humidity, 20 oC temperature, 14 hours light-2000 lux, and 10 hours darkness). At the end of the 14th day, the germination rate was calculated and the fresh weight of the shoots and roots, and length of shoots and roots were determined. The results obtained in this study indicated that the coating treatments improved to germination properties of Lolium perenne (L.) seeds under drought stress.
