A polar gibberellin active in the dwarf rice (Oryza sativa L.) seedling and barley (Hordeum vulgare L.) half-seed assays was extracted from immature sour cherry (Prunus cerasus L.) seed and identified as gibberellin A(32) by gas-liquid chromatography and selected ion monitoring.

Despite senescence-induced chlorophyll depletion in plants has been widely studied, the enzymatic background of this physiologically regulated process still remains highly unclear. The purpose of this study was to determine selected biochemical properties of partially purified fractions of chlorophyllase (Chlase, chlorophyll chlorophyllido-hydrolase, EC 3.1.1.14) from leaves of three Prunus spe...

abstract sour cherry (prunus cerasus l.) is an important iranian-native fruit, considered highly perishable commodity which cannot be stored for any length of time. on this study, effect of three gas compositions (ambient, 5% o2+5% co2+90% n2 and 10% o2+15% co2+75% n2) and two storage temperatures (0 and 5 °c) on two sour cherry cultivars namely erdy jubileum and erdy botermo was studied in a c...

Gametophytic self-incompatibility (GSI) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic S-locus, termed S-haplotype. This study characterizes a pollen part mutant of the S(1)-haplotype present in sour cherry (Rosaceae, Prunus cerasus L.) that contributes to the loss of GSI. Inheritance of S-haplotypes from reci...

Tetraploid sour cherry (Prunus cerasus L.) exhibits gametophytic self-incompatibility (GSI) whereby the specificity of self-pollen rejection is controlled by alleles of the stylar and pollen specificity genes, S-RNase and SFB (S haplotype-specific F-box protein gene), respectively. As sour cherry selections can be either self-compatible (SC) or self-incompatible (SI), polyploidy per se does not...

Flow of sour cherry (Prunus cerasus L. cv. Montmorency) gum solutions through a glass capillary was Newtonian for pressure gradients from 0 to 1.8 megapascals per meter, and hydraulic conductance was inversely proportional to solution viscosity in this range. However, flow became plastic at pressure gradients above 1.8 megapascals per meter, resulting in a decrease in solution viscosity. The ma...

Sour cherry (Prunus cerasus) in the genus Prunus in the family Rosaceae is one of the most popular stone fruit trees worldwide. Of known sour cherry cultivars, the Schattenmorelle is a famous old sour cherry with a high amount of fruit production. The Schattenmorelle was selected before 1650 and described in the 1800s. This cultivar was named after gardens of the Chateau de Moreille in which th...

A partial linkage map was constructed for the sweet cherry (Prunus avium L.) cultivar Emperor Francis from a population of 56 microspore-derived callus culture individuals. The callus cultures were genotyped for two allozymes and 90 random amplified polymorphic DNA (RAPD) markers using 79 random decanucleotide DNA primers and the polymerase chain reaction (PCR). Eighty-nine markers mapped to 10...
