Abstract The article presents the results of many years research on new valuable reed fescue bluegrass crop attracting to fodder production region. Rational combinations main crop-forming factors were established: timing, sowing methods and their effect productivity when used for seed purposes, ensuring receipt 400 800 kg/ha seeds from 20 30 t/ha green mass. Reed fescue, optimizing conditions s...

The coordination of metabolic processes to allow increased nutrient uptake and utilization for macromolecular synthesis is central for cell growth. Although studies of bulk cell populations have revealed important metabolic and signaling requirements that impact cell growth on long time scales, whether the same regulation influences short-term cell growth remains an open question. Here we inves...

Having been introduced to the northern edge of Asian tropics, the rubber tree (Hevea brasiliensis) has become deciduous in this climate with seasonal drought and cold stresses. To determine its internal nutrient strategy during leaf senescence and deciduous periods, we investigated mature leaf and senescent leaf nutrients, water-soluble soil nutrients and characteristics of soil microbiota in n...

Inorganic N is available to plants from the soil as ammonium [Formula: see text] and nitrate [Formula: see text]. We studied how wheat grown hydroponically to senescence in controlled environmental chambers is affected by N form ([Formula: see text] vs. [Formula: see text]) and CO(2) concentration ("subambient," "ambient," and "elevated") in terms of biomass, yield, and nutrient accumulation an...

The capture of patchily distributed nutrients by tree roots has received extensive research, but the fate of those nutrients has not. We performed experiments to determine if nutrient transport within tree species is preferentially transported from specific roots to specific branches. Saplings of five species with contrasting growth requirements were examined: two Betula species (B. papyrifera ...

[1] In an evergreen Mediterranean shrubland we conducted a 6-year field experiment simulating the warming and drought projected by general circulation models and ecophysiological models for the next decades: 20% reduction of soil moisture and 1 C of temperature increase. We tested whether warming and drought have effects on Ca, Fe, Mg, Mo, Na and S availability, concentrations and accumulation ...
