14In recent years a growing interest to widen the cherry (Prunus avium L.) 15 production calendar results in cultivation out of the traditional cultivation areas. Since 16 cherry has high chilling requirements, this often causes erratic cropping related to 17 phenological alterations. However, appropriate phenological characterisation and 18comparison is hampered, due to the lack of a consensus phenological scale for this 19 species. In this work we have characterised flower development in sweet cherry, 20 framing it in the BBCH scale. For this purpose, the phenology of two cherry cultivars 21 has been characterized over two consecutive years and adapted to the BBCH code, and 22 flower development has been framed within the principal growth stages of this code. 23This provides a unified standardised approach for phenological comparative studies. 24 25

“…A third closely related species, the tetraploid ground cherry P. fruticosa Pall., hybridizes freely with P. cerasus, contributing to genetic and morphological diversity, as well as reduced fertility, in sour cherry (Iezzoni 2008). Dirlewanger et al (2004) discussed the potential value of several wild species closely related to P. persica -namely P. davidiana, P. kansuensis, and P. mira -as possible sources of resistance to several important pests and diseases of peach.…”

“…In the case of cherries (subgenus Cerasus), there are two major species that are cultivated for fruit: diploid sweet cherry, P. avium, and tetraploid sour cherry, P. cerasus L. (Iezzoni 2008). A third closely related species, the tetraploid ground cherry P. fruticosa Pall., hybridizes freely with P. cerasus, contributing to genetic and morphological diversity, as well as reduced fertility, in sour cherry (Iezzoni 2008).…”

“…Carraro et al (2002) reported that several wild species of Prunus -P. spinosa, P. cerasifera, and P. domestica -serve as hosts for the phytoplasma that causes European stone fruit yellows (EFSY), a disease of many cultivated Prunus species, and the psyllid vector (Cacopsylla pruni) that transmits the disease. Similarly, P. virginiana serves as an alternate host for X-disease, a phytoplasma disease of cherries transmitted by leafhoppers (Iezzoni 2008). Damsteegt et al (2007) showed that 40 species and varieties of Prunus, including many wild species native to the US, were susceptible to infection by plum pox virus, which causes Shakra disease, considered the most important viral disease of stone fruits in Europe, and maintained infections through repeated cycles of cold-induced dormancy over 4 years.…”

“…At the same time, Gradziel (2003) has demonstrated that interspecific hybridization and backcrossing can provide an effective means of introgressing desirable genes from wild species into both peach and almond cultivars. Wild species have been important in a few cases as sources of disease resistance for Prunus crop species, e.g., resistance to plum pox virus in P. armeniaca derived from P. mandshurica (Ledbetter 2008), and resistance to cherry leaf spot in P. cerasus derived from P. maackii and P. canescens (Iezzoni 2008). Hybrids resulting from a cross between P. persica and P. davidiana were used to select for resistance to powdery mildew, peach green aphid, and plum pox virus (Kervella et al 1998).…”

The aim of this study was to examine the dimensions and surface morphology of pollen grains of some sweet and sour cherry genotypes through scanning electron microscopy (SEM) as an additional alternative identification tool. In vitro pollen germination and pollen tube length as indicators of their viability were determined as well. Observations were carried on 10 sweet cherry (Prunus avium L.) and 7 sour cherry (Prunus cerasus L.) genotypes. All genotypes had prolate, tricolpate pollen grains, and striate exine ornamentation, with more parallel longitudinal ridges. Significant differences among genotypes within species and between species were found for most pollen grain characteristics and exine ornamentation. In both sweet and sour cherry the largest variability was recorded for colpus length (CV = 15.0% and 12.9%, respectively). For sweet cherry genotypes, in vitro pollen germination and pollen tube length ranged between 1.4% to 51.5% and 360.4 to 669.3 μm respectively, while for sour cherries they ranged from 15.5% to 37.0% and 96.3 to 960.2 μm, respectively. The results of the correlation analysis showed that in vitro pollen germination correlated positively with pollen length/pollen width (L/W) ratio (r = .640) and furrow width (r = .588), and negatively with the number of ridges (r = −.517), while pollen tube length was not significantly correlated with any of the studied characteristics. Principal component analysis (PCA) revealed that pollen length, pollen width, L/W ratio, colpus length, mesocolpium width, and ridge width are relevant tools to discriminate among the studied genotypes. The measurements made on pollen grains did not reveal individually big differences, but when all features were considered together, the pollen of each genotype exhibited a unique pattern. The distribution on the scatter plot showed considerable variation among sweet and sour cherry genotypes based on pollen morphological characteristics, which led to their distribution into two separate groups. This demonstrates the ability to distinguish cherry species based on pollen morphological characteristics determined by SEM. To improve discriminative ability for genotypes within species combination between pollen ultrastructural analysis, morphological and molecular markers is desirable, in subsequent work.Research Highlights Significant differences in pollen characteristics between sweet and sour cherry. Significance of pollen morphology in taxonomic differentiation. Significance of SEM studies for the taxonomic identification.
