ALTERNATE BEARING OF FRUIT TREES

Alternate Bearing in Fruit Trees1

Changes of phenolic compounds and non-structural carbohydrates on alternate bearing cycle in ‘Kinnow’ mandarin trees

In this study we have demonstrated the variations of carbohydrates and phenolic compounds present in the leaves and stems of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees in alternate bearing cycle and the possible involvement of these compounds to flower bud formation process. The amounts of these compounds were determined in the leaves and stems of “on” and “off” trees  monthly  from Nov...

Seasonal changes in carbohydrate and nitrogen contents of olive trees ʻFishomiʼ cultivar in several parts under alternate bearing conditions

Some olive cultivars possess high tendency to alternate bearing, which have a minus economic effect on olive industry. The experiment was performed in an olive orchard located in Shiraz region. Monthly monitoring of concentrations of unstructured carbohydrates (glucose, fructose, sucrose, mannitol and starch), protein, nitrogen, potassium and phosphorus in leaves, branches and roots of olive tr...

The Role of Olive Trees Distribution and Fruit Bearing in Olive Fruit Fly Infestation

The role of fruit bearing percentage in olive fruit fly infestation is investigated through a simulation model where the spatial law of dispersion distances were modeled via an appropriate exponential law. The dispersal of olive fruit flies was simulated for two distinct cases, an olive grove with no olive fruits and an olive grove with 100% olive fruit bearing. Results showed that when no oliv...

The effect of vehicular air pollution on leaf anatomical characters of some fruit-bearing trees (cause study: traditional Qazvin gardens)

Background and Objective: Air pollution, especially the portion related to Motor vehicles, is a serious problem in many heavily polluted areas in the world. This investigation was conducted to study the effects of the air pollution on the anatomical structure of leaf in some valuable fruit-bearing trees in Traditional Qazvin gardens. Materials and Methods: In this study, 72 leaf samples were r...
