تشکیل میوه تحت تأثیر عوامل مختلف ژنتیکی درختان میوه و فیزیکوشیمیایی محیط قرار میگیرد و بروز حالت نامناسب در هر کدام از عوامل یاد شده باعث کاهش گردهافشانی، تلقیح، تشکیل میوه و درنهایت عملکرد پایین میشود. جوانهزنی و رشد لوله گرده یک مرحله اساسی در باروری و تشکیل میوه ارقام مختلف گیلاس است. در باغات اطراف کلان شهرها این پدیده ممکن است تحت تأثیر تنش عناصر سنگین ناشی از آلودگی محیطزیست قرار گیر...
Climate change is increasing sweet cherry (Prunus avium (L.) L.) production under cover systems such as high tunnels, rain covers, and nets. The objective of this review was to provide an overview the environmental factors physiological responses involved in different types protective covering systems. most important affected by are photosynthetically active radiation (PAR), temperature, relati...
Representatives of the Prunus genera, found in almost every country and continent, have been recognized not only for their delicious fruits nuts, but also because beneficial properties. To date, numerous cultivars phytochemically studied, leading to identification various compounds including terpenes, tannins, flavonoids, phenolic acids, carotenoids, fatty so on. Pharmacological studies on spec...
The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old ‘Summit’ and ‘Hedelfinger’ trees on rootstock Gisela 5 in Fruit Growing centre Gačnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, th...
Sweet cherry (Prunus avium L.) fruits are characterised by a short shelf life. To extend the life, pre-storage hydrocooling is carried out to reduce their temperature before storing them in cold storage. During 2015 and 2016, treatment on of two sweet cultivars, 'Kordia' 'Regina', from orchards locality Trebinje, was performed. Samples both cultivars were subjected an automatic system at 0.9 ºC...
Translocation of nitrogen in the xylem of field-grown cherry and poplar trees during remobilization.
Studies of small trees growing in pots have established that individual amino acids or amides are translocated in the xylem sap of a range of tree species following bud burst, as a consequence of nitrogen (N) remobilization from storage. This paper reports the first study of N translocation in the xylem of large, deciduous, field-grown trees during N remobilization in the spring. We applied 15N...
In a trial to determine if flowering cherries (Prunus serrulata Lindl.) were a source of little cherry disease, infection was found in seven of 10 species and cultivars tested. In an orchard trial with the cultivar 'Lambert', fruit symptoms of little cherry occurred in infected trees in the fifth year of fruiting, 8 years after planting. The symptoms also occurred in the two succeeding years, a...
