effect of pollen load size and source (self, outcross) on seed and fruit production in highbush blueberry cv. 'bluecrop' (vaccinium corymbosum; ericaceae).	reproductive fitness of a plant is ultimately determined by both number and quality of seed offspring. this is determined by sexual selection of pollen microspores and ovules during pollination and fertilization. these processes may include pollen competition and seed abortion, which reduce the number of microspores and ovules available for final seed production. thus, even an excess of pollen microspores to ovules does not result in fertile seeds equal to ovule number. we investigated pollen re ...	2000	11080108

protective activities of vaccinium antioxidants with potential relevance to mitochondrial dysfunction and neurotoxicity.	both the neurotransmitter dopamine (da) and a neurotoxic metabolite, 6-hydroxy da, can be oxidized to generate hydrogen peroxide and other reactive species (ros). ros promote oxidative stress and have been implicated in dopaminergic neurodegeneration, e.g., parkinson's disease (pd). there is also evidence for a relation between catecholamine-mediated oxidative damage in dopaminergic neurons and the effects of these neurotransmitters on the redox state of cytochrome c (cytc). in neurons and other ...	2007	16956663
the influence of auxins on the biosynthesis of isoprene derivatives in callus cultures of vaccinium corymbosum var. bluecrop.	callus cultures of vaccinium corymbosum var. bluecrop were optimized for their isoprene derivatives production by supplementing schenk-hildebrandt (sh) medium with constant concentration of kinetin (2.32 microm) and two different amounts of selected auxins. every auxin, except for iba, used in 10-time higher concentration (2,4d, naa, iaa, noa) stimulated biosynthesis of beta-sitosterol and inhibited triterpene synthesis. quantitative analysis of isoprene derivatives in callus biomass collected o ...	2013	16989318
blueberry (vaccinium corymbosum l.).	recent advances in plant biotechnology have led to a reliable and reproductive method for genetic transformation of blueberry. these efforts built on previous attempts at transient and stable transformation of blueberry that demonstrated the potential of agrobacterium tumefaciens-mediated transformation, and as well, the difficulties of selecting and regenerating transgenic plants. as a prerequisite for successful stable transformation, efficient regeneration systems were required despite many r ...	2006	17033069

anti-inflammatory and antinociceptive properties of blueberry extract (vaccinium corymbosum).	blueberries are among the edible fruits that are recognized best for their potential health benefits. the crude extract from vaccinium corymbosum was assessed in anti-inflammatory and antinociceptive models. the crude hydroalcoholic extract was administered orally at doses of 100, 200 or 300 mg kg (-1) for all the assays. in the carrageenan test, the crude extract reduced rat paw oedema by 9.8, 28.5 and 65.9%, respectively. for the histamine assay, the reductions of oedema were 70.1, 71.7 and 81 ...	2007	17430644
seasonal variation of temperature response of respiration in invasive berberis thunbergii (japanese barberry) and two co-occurring native understory shrubs in a northeastern us deciduous forest.	in the understory of a closed forest, plant growth is limited by light availability, and early leafing is proposed to be an important mechanism of plant invasion by providing a spring c "subsidy" when high light is available. however, studies on respiration, another important process determining plant net c gain, are rare in understory invasive plants. in this study, leaf properties and the temperature response of leaf respiration were compared between invasive berberis thunbergii, an early leaf ...	2007	17609983
leaf phenology and seasonal variation of photosynthesis of invasive berberis thunbergii (japanese barberry) and two co-occurring native understory shrubs in a northeastern united states deciduous forest.	early leafing and extended leaf longevity can be important mechanisms for the invasion of the forest understory. we compared the leaf phenology and photosynthetic characteristics of berberis thunbergii, an early leafing invasive shrub, and two co-occurring native species, evergreen kalmia latifolia and late leafing vaccinium corymbosum, throughout the 2004 growing season. berberis thunbergii leafed out 1 month earlier than v. corymbosum and approximately 2 weeks prior to the overstory trees. the ...	2007	17647021

transmission, field spread, cultivar response, and impact on yield in highbush blueberry infected with blueberry scorch virus.	scorch disease caused by blueberry scorch virus (blsv) spreads rapidly and radially from foci of infection. healthy potted blueberry plants became infected when placed next to diseased field bushes from early may through mid-august. the aphid fimbriaphis fimbriata, collected from infected field bushes, transmitted blsv to healthy blueberry plants in controlled tests and was regarded as the most important means by which bushes in commercial fields became infected. the rate of spread in the symp-t ...	2000	18944552
transmission and the role of honeybees in field spread of blueberry shock ilarvirus, a pollen-borne virus of highbush blueberry.	abstract the rapid and random spread of blueberry shock ilarvirus (blshv) in commercial plantings suggested that insects played a role in transmission. transmission from infected field plants to trap plants only occurred during bloom, indicating that flowers were the avenue for infection and flower-visiting insects including pollinators were involved. trap plants readily became infected during bloom when a honeybee hive was included in cages with diseased field plants and trap plants. there was ...	1999	18944785
antioxidant activity of blueberry fruit is impaired by association with milk.	the antioxidant properties of dietary phenolics are believed to be reduced in vivo because of their affinity for proteins. in this study we assessed the bioavailability of phenolics and the in vivo plasma antioxidant capacity after the consumption of blueberries (vaccinium corymbosum l.) with and without milk. in a crossover design, 11 healthy human volunteers consumed either (a) 200 g of blueberries plus 200 ml of water or (b) 200 g of blueberries plus 200 ml of whole milk. venous samples were ...	2009	19135520
herbivore-induced volatiles in the perennial shrub, vaccinium corymbosum, and their role in inter-branch signaling.	herbivore feeding activates plant defenses at the site of damage as well as systemically. systemic defenses can be induced internally by signals transported via phloem or xylem, or externally transmitted by volatiles emitted from the damaged tissues. we investigated the role of herbivore-induced plant volatiles (hipvs) in activating a defense response between branches in blueberry plants. blueberries are perennial shrubs that grow by initiating adventitious shoots from a basal crown, which produ ...	2009	19159981
patterns of nocturnal rehydration in root tissues of vaccinium corymbosum l. under severe drought conditions.	although roots in dry soil layers are commonly rehydrated by internal hydraulic redistribution during the nocturnal period, patterns of tissue rehydration are poorly understood. rates of nocturnal rehydration were examined in roots of different orders in vaccinium corymbosum l.
