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...
متن کاملSeasonal 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...
متن کاملInsight into Alternate Bearing of Pecan
The fundamental cause of alternate bearing in pecan [Carya illinoinensis (Wangenh.) K. Koch] is unknown, but is closely linked to the size of the dormant season carbohydrate pool. Nut yields (over a period of up to 78 years) were evaluated, for 66 cultivars, in regards to alternate bearing intensity (I). Best-fit regression analysis indicates no association between I and fruit ripening date (FR...
متن کاملEffect of Increasing Fertilization Levels on Alternate Bearing of Olive Cv. "Picual"
The present study was carried out for three successive seasons 2008/2009, 2009/2010 and 2010/2011 on fifteen years old of olive trees cv. Picual to reduce the degree of alternate bearing through fertilization by NPK over than the rates recommended by the Ministry of Agriculture and Lands Reclamation. The obtained results showed that, fertilizing olive trees with 50% over NPK recommended doses i...
متن کاملCorrigendum: Direct coupling: a possible strategy to control fruit production in alternate bearing
We investigated the theoretical possibility of applying phenomenon of synchronization of coupled nonlinear oscillators to control alternate bearing in citrus. The alternate bearing of fruit crops is a phenomenon in which a year of heavy yield is followed by an extremely light one. This phenomenon has been modeled previously by the resource budget model, which describes a typical nonlinear oscil...
