The content of chlorogenic acid was studied in three scab resistant apple cultivars (‘Topaz’, ‘Gold Rush’, ‘Goldstar’) and two scab susceptible ones (‘Golden Delicious Weinsberg’, ‘Golden Delicious Clone B’) growing in Laboratory Field of the Biotechnical Faculty in Ljubljana. The leaf samples were collected four times in 30 day intervals between 12 June and 10 September 2001 and analysed using...

Fruits of Ziziphus jujuba Mill. (family: Rhamnaceae), known as Indian jujube or "Ber," are of potential nutritional and medicinal value. The objectives of the present study were to estimate bioactive compound maslinic acid by HPTLC method and to evaluate in vitro antioxidant and hepatoprotective activity of eight cultivars of Indian jujube. Maslinic acid and the fruit pulp of various cultivars ...

DNA markers are useful tools that play an important role in plant cultivar identification. They are usually based on polymerase chain reaction (PCR) and include simple sequence repeats (SSRs), inter-simple sequence repeats, and random amplified polymorphic DNA. However, DNA markers were not used effectively in the complete identification of plant cultivars because of the lack of known DNA finge...

The cultivated apple (Malus domestica) is one of the most important fruit crops cultivated in different regions of the world including Iran. For production and breeding of high quality apple, the knowledge of genetic diversity of the cultivated apples  is  necessary. Therefore we studied genetic diversity of 25 genotypes by using ISSR molecular markers. In present study, ten ISSR primers produc...

Over the last 60 years, planting densities for apple have increased as improved management systems have been developed. Dwarfing rootstocks have been the key to the dramatic changes in tree size, spacing and early production. The Malling series of dwarfing rootstocks (M.9 and M.26) have been the most important dwarfing rootstocks in the world but are poorly adapted in some areas of the world an...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

Physical, chemical and sensory changes of cut apple (cv. Jonagored) stored in the dark at 4 C were evaluated. Colour was found to be the critical parameter for this product. Apple cubes underwent severe surface browning primarily during the initial days of storage. The shelf-life of cut apple was therefore very limited, to three days maximum. Sensory analyses and objective quality evaluations o...
