Seasonal Changes in the Photosynthetic Rate in Apple Trees : A Comparison between Fruiting and Nonfruiting Trees.
Seasonal changes in photosynthesis of apple trees (Malus domestica Borkh.) were monitored to examine the effect of source-sink interactions on photosynthesis and photorespiration. Elevated photosynthetic rates were observed during two periods of the growing season and correlated with the fruiting process. The first period of increased photosynthetic rates was during the bloom period, when spur ...
متن کاملThe Effect of Chemical Thinning on Seasonal Changes of Mineral Nutrient Concentrations in Leaves and Fruits of ‘Soltani’ Apple Trees
ABSTRACT- The purpose of this study was to elucidate the effects of chemical thinning on seasonal variations of leaf and fruit mineral compositions of ‘Soltani’ apple trees. Treatments, including unthinned control, naphthalene acetic acid (NAA) at 5 and 10 mg L-1, naphthaeneacetamide (NAD) at 25 and 50 mg L-1, benzyladenine (BA) at 50 and 100 mg L-1 and carbaryl at 500 and 1000 mg L-1 were appl...

متن کاملA Viroid Resembling Hop Stunt Viroid in Infected Apple Trees with Apple Scar Skin Disease in the Northeast of Iran
Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...
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...
