the fact that ‘Russet Burbank’, a later sport of ‘Burbank's Seedling’, was not particularly susceptible to late blight might have been an achievement at its highest level ( Inglis et al., 1996 ) ( Table 1 ). Although it is often said that no resistance

Fruit color is a commercially important quality for sand pear ( Pyrus pyrifolia Nakai). Sand pear can be divided into russet, semi-russet, and green types based on the color of the peel, which is typically composed of a cuticle layer, an epidermis

Russeting is an important surface disorder in smooth-skinned cultivars of apple ( Malus × domestica Borkh.) and pear that results in significant economic losses. The brownish, dull appearance of russeted fruit is unattractive to the consumer who

Russet is a surface defect of apple fruit that can significantly reduce fresh market value. Fruit with an aggregate of more than 10% of the surface area covered with russet are excluded from both the U.S. Extra Fancy and U.S. Fancy grades, and

Russeting, also known as cuticle cracking, has become a common problem in greenhouse tomato production and an important concern for commercial growers, and the causes of its development are extremely complex ( Demers et al., 2001 ; Dorais et al

Russeting is an important disorder of the fruit surface of many fruit crops including apple ( Faust and Shear, 1972a , 1972b ). In anatomical terms, a russeted area represents an area of periderm comprising phellogen and phellem. The periderm is

Peel russeting is a commonly encountered, economically important surface defect in a number of horticultural crops, including apple ( Faust and Shear, 1972a ), tomato ( Bakker, 1988 ), banana ( Williams et al., 1990 ), and plum ( Michailides, 1991

Russeting is an important peel defect in many apple cultivars, and russeted fruit is subject to reduced value ( Faust and Shear, 1972a ). Apple cultivars differ in their susceptibility to russeting, and fruit in early stages of development is more

Clusters of Vitis labruscana cv. Concord were grown either in full sun or canopy shade, and either not sprayed or sprayed with 3.4 Kg/Ha chlorothalonil every 2 wk from pre-bloom to veraison. Only sun-exposed, sprayed fruit produced skin russeting. Clusters of the very susceptible V. vinifera cv. Rosette were grown in direct sun, sprayed with chlorothalonil 4 times from bloom to veraison, in the presence or absence of purported anti-russeting agents. Heavy russet occurred in all treatments. Russet initiation was similar in the 2 cvs.: epidermal cells first died beneath spray residue in full sun, a phellogen then arose in the hypodermis, followed by periderm. Epidermal death began in `Rosette' within a wk of the bloom spray, but in `Concord' only after 2-3 wk post bloom and 3 sprays. `Concord' russet generally appeared as patches or scabs, whereas `Rosette' russet ranged from freckles, welts, scabs to large smooth burnished areas. In both cvs., unbroken russet consisted of uniform layers of phellum. New, deeper periderm initials arose beneath checks and cracks which formed as fruit enlarged. In `Concord', but not `Rosette', the daughter cells of each such initial were often enclosed in the original cell wall. In all cases of russet, cell walls in the periderm were suberized and sometimes lignified. Cells also contained much phenolic material.
