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...
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 کاملSeasonal variations of serum copper concentration in Raeini cashmere goats
The aim of this study is to determine the serum copper (Cu) concentration found in Iranian Raeini cashmere goats in different seasonal and climatic conditions. Twenty four male (6 to 18 months old) and 48 female (6 to 18 and 18 to 30 months old) Raeini goats were selected from the station, rural, and nomadic flocks. The average Cu concentrations among the male and female goats were 0.5 ± 0.04 a...
متن کاملSeasonal 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 کاملCharacterization, localization, and seasonal changes of the sucrose transporter FeSUT1 in the phloem of Fraxinus excelsior
Trees are generally assumed to be symplastic phloem loaders. A typical feature for most wooden species is an open minor vein structure with symplastic connections between mesophyll cells and phloem cells, which allow sucrose to move cell-to-cell through the plasmodesmata into the phloem. Fraxinus excelsior (Oleaceae) also translocates raffinose family oligosaccharides in addition to sucrose. Su...
