In northern Europe, replacing winter barley with winter wheat as the preceding crop for winter oilseed rape (Brassica napus L.; WOSR) often results in a delayed WOSR sowing and poor autumn growth. Based on data from a field experiment running in 2009/2010, 2010/2011, and 2012/2013, this study aims (i) to investigate how a delayed sowing method affects seed yield, N offtake with the seeds, and a...

two experiments studied the effects of canola or sunflower seed supplementation on conjugated linoleic acid (cla) concentration in milk fat of lactating cows. in each experiment, only eight cows in early lactation were available to assign to one of two treatments in a completely randomized design and were fed individually for 12 wk. experiment 1 compared similar diets with or without the additi...

seed bank is a central topic for plant community restoration. we determined the potential and regeneration capacity of soil seed banks of woody plant patches in conservation of the vegetation in an alpine habitat, since vegetation has completely disappeared in some sites by intensive grazing in the habitat. the study was done in mountainous area of alborz in iran. a total of 20 individual shrub...

Ground flora is an important response variable to monitor after tree thinning and prescribed burning treatments de signed to restore Arizona ponderosa pine {Pinusponderosa P.& C. Lawson) forests. This paper reviews published liter ature on the effects of thinning and burning on ground flora in Arizona ponderosa pine forests in five main categories of research: ground flora biomass, species dive...

A seed-specific 2S albumin gene and its promoter region of grape (Vitis vinifera L.) were isolated using an improved thermal asymmetric interlaced PCR that allowed efficient amplification of target sequence of up to 3 kbp in length directly from genomic DNA. The 2S albumin VvAlb1 (for V. vinifera 2S albumin 1) gene from different grape cultivars encompasses a coding region of 504-540 nucleotide...

Seeds are under strong pressure from seed predators. Therefore any physical seed trait increasing the chances of the seed’s survival should undergo positive selection. Seed color polymorphism, varying from pale to dark seeds, occurs in Scots pine (Pinus sylvestris), a keystone species of coniferous forests in Eurasia. This phenomenon can be explained by the production of large quantities of emp...

Chronic intermitted hypoxia including sleep breathing disorder leads to brain injury. This study explores the potential therapeutic effects of grape seed proanthocyanidin as a neuroprotective agent. A rat model of chronic intermittent hypoxia was employed, and the animals were given low or high doses of grape seed proanthocyanidin. The ultrastructure changes in the brain, the biochemical compon...
