Nonchemical quarantine treatments, using a combination of short-duration high temperatures under low oxygen, elevated carbon dioxide atmospheric environment were developed to control codling moth in sweet cherries, Prunus avium (L.). The two treatments developed are a chamber temperature of 45 degrees C for 45 min and a chamber temperature of 47 degreesC for 25 min under a 1% oxygen, 15% carbon...

Microsatellite markers were used to describe the genetic variability of four seed stands of wild cherry (Prunus avium L.). One hundred and thirty one individuals were genotyped at ten nuclear microsatellite loci. Total genetic diversity was high (H(E) = 0.704), while differences between stands were small but significant (F(ST) = 0.053, G'(ST) = 0.234). There was a significant amount of clonal r...

A hypothesis that cherry rootstocks grown under optimal nutrient conditions are affected less by Pratylenchus penetrans infection than those grown under deficient nutrient conditions was tested by growing four Prunus avium L. rootstocks ('Mazzard', 'Mahaleb', 'GI148-1', and 'GI148-8') at a soil pH of 7.0 over a period of 3 months under greenhouse conditions (25 ñ 2 degrees C). Pratylenchus pene...

Sweet cherry (Prunus avium L.) is one of the most important stone fruit species in Bulgaria. The known to be susceptible more than 30 viruses. Among them are prune dwarf virus (PDV), prunus necrotic ringspot (PNRSV) and apple mosaic (ApMV), ilarviruses. Testing for these viruses required certification schemes order provide virus-tested propagated material fruit-growing industry prevent their di...

Many species in Rosaceae, Solanaceae, and Plantaginaceae exhibit S-RNase-based self-incompatibility (SI). In this system, the pistil and pollen specificities are determined by S-RNase and the S locus F-box protein, respectively. The pollen S determinant F-box protein in Prunus (Rosaceae) is referred to by two different terms, SFB (for S-haplotype-specific F-box protein) and SLF (for S locus F b...
