We examined intraseasonal changes in maize phenology and heat stress exposure over the 1979–2008 period, using Mozambique meteorological station data and maize growth requirements in a growing degree-day model. Identifying historical effects of warming on maize growth is particularly important in Mozambique because national food security is highly dependent on domestic food production, most of ...

We examined changes in nitrogen (N) net uptake and activity and amount of plasma membrane H+-ATPase (PM-ATPase) in roots of hydroponically cultured Scots pine (Pinus sylvestris L.) seedlings throughout a simulated second growing season. Seedlings were grown with low (0.25 mM N) or high (2.5 mM N) nutrient availability to determine whether root PM-ATPase is dependent on an external nutrient supp...

Field population densities of Ditylenchus dipsaci associated with shoot tissue of Phlox subulata were monitored during two consecutive growing seasons and intervening periods of overwintering and plant storage. The population density increased significantly through four peaks during the first growing season, and decreased significantly during storage at 5-7 C or overwintering in the field. Duri...

primary bud necrosis (pbn) in grapevine is a physiological disorder that leads to death of fruitful buds and yield loss. the aim of this study was to determine the changes in soluble sugars and starch and their relationship to the incidence of the primary bud necrosis in askari grapevine. experiment was conducted in a vineyard that the vines were 15 years old, with a head system, vines spaced 2...

Two prospective, multi-centre, observational studies (GlaxoSmithKline [GSK] identifier No. 110938 and 112519) were performed over 2 influenza seasons (2007-2008 and 2008-2009) in the Republic of Korea (ROK) with the aim to evaluate the burden of laboratory-confirmed influenza (LCI) in patients ≥ 50 years of age seeking medical attention for acute respiratory illness (ARI). The median participan...

Forty-five male yaks (born April 2001) were studied to determine how seasonal changes on the Qinghai-Tibetan plateau affected BW and body composition. Thirty yaks were weighed monthly from birth to 26 mo of age to determine seasonal changes in BW. The remaining 15 yaks were allocated randomly to five groups (three yaks per group), designated for slaughter at 13, 15, 18, 22, and 25 mo to measure...

120 Journal of Plant Registrations, Vol 2, No. 2, May 2008 Drought stress reduces dry bean seed yield in most production regions worldwide (White and Singh, 1991). The release of pinto bean (Phaseolus vulgaris L.) germplasm CO46348 (Reg. No. GP-275, PI 651500) will provide plant breeders with drought-tolerant, pinto bean germplasm that takes advantage of a full growing season (95–98 d) and has ...

BACKGROUND GPs play a major role in influenza epidemics, and most patients with influenza-like-illness (ILI) are treated in general practice or by primary care doctors on duty in out-of-hours services (OOH). Little is known about the surge capacity in primary care services during an influenza pandemic, and how the relationship between them changes. AIM To investigate how general practice and ...

Two cultural treatr7zents were applied in an overstocked loblolly pirze (Pinus taeda L.) plantation (2,900 trees/ha after eight growing seasorzs): precom~nercial tlzinning (Yes or No) to 747 tt-ees/lza after the eighth growing season and broadcast fertilizatiorz (Yes or No) with diamrrzonium phosphate (150 kg/ha of P and 135 kg/ha of N) early in the ninth growing season. Total height and diamet...
