2.1 Introduction

Cherry trees are a paradigm of how flower biology influences the final crop. While some

8 weeks elapse from flower to mature fruit, the crop load is established very early after flowering, within approximately 4  weeks, although preharvest fruit abscission (‘June drop’) can modify the apparent crop load in some years. Differences between growing and non-growing flowers are determined as early as 1 week after pollination, a time that is concomitant with fertilization (Hedhly et al.,

2007). What occurs during this short bloom time, along with the prebloom stages of flower development, are critical to understand fruit set.

17.1 Introduction

Cherry nutritional composition, phytochemical content and antioxidant capacity should be considered on a cultivar/genotype basis since many new cultivars that enter into the market through the breeding programmes

(Sansavini and Lugli, 2008) have apparent differences for both qualitative and phytochemical antioxidants contents (Ballistreri et al., 2013; Goulas et al., 2015). The breeding programmes have led to the release of numerous cultivars, where the main attributes considered were bearing habits, ripening period, fruit size and yield, increased fertility, reduced susceptibility to environmental damage and diseases, extension of seasonality, especially for early-ripening genotypes, and resistance to cracking. However, to the best of our knowledge, phytochemical status and nutritional properties are not being evaluated through the breeding programmes.

19.1 Introduction

Sweet cherry is an edible drupe that can be classified according to the physical or pomological characteristics of the fruit. The Bigarreau and Duroni groups (Italy) include cultivars with firm flesh, while the Guigne

(France), Gean (England) and Tenerine groups

(Italy) include soft and tender flesh. Only

Bigarreau cherries are firm enough for commercial use, being better able to withstand the rigours of harvest, postharvest handling and long-distance transport. Fruit have either dark- or light-coloured flesh. Dark cherries are red to reddish-purple or mahogany in colour, whereas light cherries (so-called white) are yellow, usually with a pink to red partial blush on the yellow skin. Fruit vary in shape from round to oval to heart-shaped, and their pedicels vary in length from 2 to 8 cm

6.1 Introduction

Rootstocks for cherries are chosen from among taxa showing appropriate graft compatibility. Considering this criteria, Prunus avium, Prunus cerasus, Prunus mahaleb and Prunus fruticosa, as well as their hybrids and some related taxa, can be used as rootstocks.

Further factors that influence rootstock use are the diverse pedoclimatic conditions in the different sites. Rootstocks remain important tools for extending the site adaptability of sweet and sour cherry cultivars, and also allow growers to plant cherries in suboptimal sites. Although modern sweet cherry orchard systems, the so-called ‘pedestrian orchards’, require dwarfing and precocious rootstocks, the rootstocks used in sweet and sour cherry orchards are still diverse. The training system and rootstock must be considered together, and matched properly with the vigour of the soil fertility and climate of the orchard site. Growers of intensive orchards, producing hand-picked cherries for fresh market, prefer dwarfing rootstocks, which allow planting densities of up to 1000–5000 trees ha–1 (Robinson,

Cherries are infected by a range of viruses, viroids and phytoplasmas. Some of these cause severe diseases, having a significant impact on commercial cherry production.

Viruses such as prune dwarf virus (PDV) and
