Background: Blackberry is a seasonal harvested fruit that is also very fragile and perishes quickly. A comparative study was conducted to find out influence of cold storage on physicochemical parameters of wild and cultivated blackberry over a period of 12 days. Methods: The plant materials were composed of the blackberry fruit, including a compound of cultivated blackberry (Rubus spp.), and w...
We explore how the ground flora of a temperate woodland (Wytham Woods, southern England) changed in terms species-richness, cover and biomass over five decades; what drivers change were; possible future as consequence decline Fraxinus excelsior canopy dominant. Vascular plants were recorded from 164 permanent, 10x10 m plots, distributed 141 grid, 1974, 1991, 1999, 2012, 2018. Species presence f...

initial growth of quercus castaneifolia (c.a.meyer.) seedling in competition with rubus fructicosus l. was investigated in a caspian lowland intervened forest located in noor city, north of iran. the research was conducted as factorial experiment in three replications. for this purpose, seedlings of 3 and 5 mm in collar diameter (cd) were planted in areas a (covered with rubus), b (without rubu...
BACKGROUND AND AIMS In the UK, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year. The fruits of hedgerow plants are a source of winter food for frugivorous birds on farmland. It is unclear whether recent declines in pollinator populations are likely to threaten fruit-set and hence food supply for birds. The pr...
The plant pathogen Erwinia amylovora can be divided into two host-specific groupings; strains infecting a broad range of hosts within the Rosaceae subfamily Spiraeoideae (e.g., Malus, Pyrus, Crataegus, Sorbus) and strains infecting Rubus (raspberries and blackberries). Comparative genomic analysis of 12 strains representing distinct populations (e.g., geographic, temporal, host origin) of E. am...
