Cultivar and fruit size influence bruise susceptibility and some physical properties of apple fruit
ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...
متن کاملGrowth Conditions, Crop Load and Fruit Size Affect Sheepnosing in Grapefruit
We evaluated crop load, fruit yield and size in several grapefruit blocks on the central Florida Ridge and in the Indian River areas over three growing seasons to determine potential causes of elongated, sheepnosed grapefruit. Previous studies showed that relatively higher rates of N fertilization and high early season (February-July) temperatures within tree canopies resulted in high percentag...
متن کاملmodeling and assessment of crop load effect on fruit growth pattern of apple cv. red spur in karaj climatic conditions
an analysis of the stages of crop growth presents an important step in the improvement of production management. through growth analysis, planning for planting systems, fertilization, pruning operations, harvest time as well as obtaining economical yield can be more accessible. therefore, a development of mathematical models simulating plant growth would be helpful in improving crop management,...
متن کامل`McIntosh' apple fruit thinning by benzyladenine in relation to seed number and endogenous cytokinin levels in fruit and leaves
The relationship of 6-benzylaminopurine (BA)-induced fruitlet abscission to seed number and endogenous cytokinin levels in the fruit and leaves was examined in `McIntosh' apples (Malus domestica Borkh.). BA applied at the 10 mm stage of fruit development effectively thinned apple fruit and increased fruit size. The seed number of abscising fruit increased as BA concentrations increased. In pers...
متن کاملFruit Self-Thinning: A Trait to Consider for Genetic Improvement of Apple Tree
In apple (Malus×domestica Borkh), as in many fruiting crops, fruit maintenance vs abscission is a major criteria for production profitability. Growers routinely make use of chemical thinning agents to control total fruit load. However, serious threats for the environment lead to the demand for new apple cultivars with self-thinning properties. In this project, we studied the genetic determinism...
