“…This technique with the characteristics of the present study would be an effective tool to protect the plant against temperatures ≤ 0 ºC. At the same time, the increase in minimum temperatures would promote fertilization and fruit set because, according to Aras et al (1996) and Cooper and Schaffer (1985), the initial working temperature of pollinating agents, such as Aphis mellifera and Bombus spp., is greater than 10 and 5 ºC, respectively. This factor is relevant because Brevis et al (2006) and Kirk and Isaacs (2012) point out that the period of flower receptivity is approximately 4 to 5 d. Javorek et al (2002) and Kirk and Isaacs (2012) mention that this greater activity of pollinating agents would increase fruit fertilization, increase fruit size, and crop yield.…”

Blueberry production under netting has increased in recent years to mitigate the adverse effects of climate change. The objective of the present study was to evaluate the effect of different radiation intensities on rabbit-eye blueberry (Vaccinium virgatum Aiton) 'Ochlockonee' photosynthetic efficiency and productive parameters. Four treatments were established: T1 (control), T2, T3, and T4 at 0%, 30%, 60%, and 90% radiation decrease (RD), respectively, with black shedding netting. The following were recorded for each treatment: environmental conditions, photosystem II (PSII) maximum quantum yield (F v /F m ), photosystem II effective quantum yield (Φ PSII ), leaf stomatal conductance (g s ), quality parameters, and fruit yield. Results showed an increase of 4.6 ºC in mean minimum temperatures for the different netting treatments, which promote development and fruit set, as well as prevent damage at temperatures near 0 ºC. The RD treatments increased Φ PSII between 175% and 325% (P < 0.05) compared to the control. It can be concluded that netting decreased soil temperature between 1 and 3 ºC and increased minimum temperatures between 1 and 6 ºC, which promoted plant development and decreased frost damage during flowering and fruit development. Current direct radiation levels over 1000 µmol m -2 s -1 in V. virgatum inhibited productivity in T1. Netting decreased the degree of photoinhibition and increased photosystem II photochemical efficiency throughout the day, and T4 and T3 exhibited the highest efficiency.

“…Similarly, increased minimum temperatures in the high tunnels favor fertilization and fruit set since the threshold for pollinator activity, such as Apis mellifera fluctuates between 10 and 27 °C (Cooper and Schaffer, 1985), and is above 5 °C for bumble bees (Bombus spp.) (Aras et al, 1996). A higher pollinator activity increases the size and the rate of fruit ripening significantly (Javorek et al, 2002).…”

Blueberry (Vaccinium corymbosum L.) production under tunnels has spread in recent years. However, there is little information on the productive and physiological responses of blueberry grown under high tunnels. The objective of this research was to evaluate the effect of high tunnel microclimate on the physiological and productive responses of blueberries. A total of 1296 plants of highbush blueberry 'O'Neal' were grown in high tunnels, leaving the same amount of plants under open fields (control). Environmental temperature (T, °C) and relative humidity (RH, %), diffuse and total photosynthetically active radiation (PAR diffuse and PAR total , µmol m -2 s -1 ), stomatal conductance (g s , mmol m -2 s -1) and maximum photochemical efficiency of photosystem II (F v /F m ) of the leaf were measured. Fruit yield, date of harvest initiation and fruit growth rate were also determined. The maximum T was on average 10-12 °C higher inside the high tunnel than the control, whereas the minimum T averaged only 2-5 °C higher. PAR total decreased an average of 25% under tunnel, while levels of PAR diffuse increased more than 150%. The g s ranged between 42% and 99% higher in the high tunnel compared to the control, and was positive and statistically related (r 2 = 0.69**) to PAR diffuse variations. Blueberries under high tunnel recorded an accumulated yield 44% higher, while harvest started 14 d earlier compared to control. The results suggest that high tunnels in blueberries increases fruit yield and improves precocity due to higher temperatures during the flowering stage and fruit set. Particular light conditions under tunnels would favor higher leaf stomatal conductance in this crop.

“…and larger andrenids (Andrena spp.) (Finnamore and Neary 1978;Mohr and Kevan 1987;Drummond 1999, 2001;Javorek et al 2002), although other, commercially available, bees (e.g., Apis mellifera L. (Aras et al 1996;Javorek et al 2002) and Megachile rotundata F. (Stubbs and Drummond 1997)) may be useful. In fact, there was almost no fruit-set without manipulation of some sort on the flowers of Vaccinium angustifolium and V. myrtilloides (Table 2 and 3).…”

“…Although it is generally accepted that lowbush blueberries usually depend on insects, mostly bees (Hymenoptera: Apoidea) for pollination (Eck and Childers 1966;McGregor 1976;Reader 1977;Hall et al 1979;Morrissette et al 1985;Mohr and Kevan 1987;Aras et al 1996;Stubbs and Drummond 1997, 1999, 2001Javorek et al 2002), most research on pollination is from commercial lowbush blueberry barrens and there is little information from unmanaged habitats, completely natural stands, and especially the boreal forest (Kevan et al 1993;Mohr and Kevan 1987).…”

“…There is little published information on V. myrtilloides, presumably because it is of little commercial importance. It is regarded as an obligate entomophilous outcrosser (Vander Kloet and Hall 1981) and well pollinated by various bees (Morrissette et al 1985;Aras et al 1996). Reader (1977) examined the breeding strategies of V. myrtilloides in natural bogs of southern Ontario and reported that this species was self-compatible with 40% of flowers setting seed autogamously, 60-80% setting seeding set when pollination occurred between flowers of the same plant (geitonogamy), and when pollination occurred between two different plants (xenogamy), the percentage of flowers setting seed was 70%.…”

Pollination and Breeding System of Lowbush Blueberries, <em>Vaccinium angustifolium</em> Ait. and <em>V. myrtilloides</em> Michx. (Ericacaeae), in the Boreal Forest

Breeding systems and pollination requirements of two wild lowbush blueberries, Vaccinium angustifolium and V. myrtilloides, in the Canadian boreal forest in the Chapleau Crown Game Preserve, Ontario, were tested. Fruit production, size and seediness were significantly higher in samples exposed to natural pollination than in those cross-or self-pollinated by hand. There were no significant differences among artificial treatments (variously hand-pollinated and bagged) except when cross-pollination (xenogamy) was done by insect pins. In V. angustifolium, the density of flowering varied with forest age (canopy closure). It was most in open areas and least in the sites with the most mature forest. Although fruit-set and seediness varied among forest habitats of different ages, there were no significant differences between sites in forests of different ages. Thus, pollination seems to be similarly effective no matter the age of the forest. In both species, fruit-set in 1992, which had severe June frosts, was markedly poorer than that in 1993 when the flowers suffered little frost damage. The combined number of complete and incomplete seeds from the fruit among the breeding and pollination systems tested were similar; however, the ratio of complete seeds to total seeds was greater from cross-pollinated than from self-pollinated flowers. Our observations indicate that there is little natural fruit-set without insect-mediated cross-pollination and that cross-pollination provides much better fruit and seed-set than does self-pollination.
