Growth and Physiological Responses of Tundra Plants to Defoliation
In addition to extreme abiotic conditions, biotic factors such as grazing influence the growth of tundra plants. Strategies of carbon assimilation, accumulation, and utilization must not only satisfy the requirements of a rigorous physical environment but also must simultaneously adjust to the impacts associated with herbivory. Representatives of four growth forms found in northern Alaska (a de...

متن کاملthe effects of sowing rate, defoliation intensity and time of defoliation commencement on vegetative and reproductive growth of medic swards
to obtain detailed information of sowing density and defoliation intensity under more controlled conditions on herbage production and seed yield, paraggio medic was grown on raised-beds located outdoors at the waite agricultural research institute. a split split randomised block design was used. treatments comprised three sowing rates (densities): low (3 kg/ha), medium (15 kg/ha) and high (...
متن کاملChanges in Growth and Chemical Defences upon Defoliation in Maize
ÐThe eect of defoliation on growth and on levels and allocation patterns of hydroxamic acids (Hx) in maize seedlings was evaluated 6 days after treatment. No signi®cant dierences were found between defoliated and nondefoliated plants for the Hx concentration, relative Hx content and Hx-aglucone to Hxglucoside ratio in shoots, roots and root exudates, with the exception of Hx concentration in ...
متن کاملDeclines in dissolved silica concentrations in western Virginia streams (1988–2003): Gypsy moth defoliation stimulates diatoms?
[1] Dissolved silica concentrations in western Virginia streams showed a significant bias toward declines (p < 0.0001) over the time period from 1988 to 2003. Streams with the greatest declines were those that had the highest mean dissolved silica concentrations, specific to watersheds underlain by basaltic and granitic bedrock. We examined potential geochemical, hydrological, and biological fa...
