DISTRIBUTION OF COAT PROTEIN AND NUCLEIC ACID OF PLUM POX VIRUS (PPV) IN SEEDLINGS OF PEACH ROOTSTOCK GF305 AND APRICOT CV. REAL FINO

In this work, the in-plant distribution of Plum pox virus (PPV) in seedlings of peach rootstock GF305 and apricot cv.Real Hob Buffer Fino was studied.Symptom severity and the optical density with the ELISA-DASI test were determined in the leaves.Occurrence of the virus (coat protein and nucleic acid) in the stems and petioles was analyzed by tissue

The focus of this research was to evaluate genotypes for cold-tolerant germination from wild switchgrass (Panicum virgatum L.) populations collected in the Northeast USA.Switchgrass nurseries were established in 2008 and 2009 with seed collected from native stands of switchgrass in the Northeast USA between 1991 and 2008.Switchgrass seed harvested
