The main objective of this thesis was to examine the effects of climate change and simulated herbivory (artificial foliage damage) on growth responses and leaf characteristics (chemical and morphological structure and consequent palatability) of silver birch (Betula pendula) seedlings. In order to achieve this target, seedlings were grown in climate controlled closed-top chambers under ambient ...

This letter proposes and experimentally demonstrates that oxygen, through action as a surfactant, enables the growth of aluminum nanorods using physical vapor deposition. Based on the mechanism through which oxygen acts, the authors show that the diameter of aluminum nanorods can be controlled from 50 to 500 nm by varying the amount of oxygen present, through modulating the vacuum level, and by...

Citric acid may be involved in plant response to high temperature. The objective of this study was to investigate whether exogenous citric acid could improve heat tolerance in a cool-season turfgrass species, tall fescue (Lolium arundinaceum), and to determine the physiological mechanisms of citric acid effects on heat stress tolerance. The grasses were subjected to four citric acid levels (0, ...

The high temperature may cause difficult growth or bloom in the summer, which is key problem limiting cultivation and application of dahlia. photosynthetic physiological mechanisms dahlia under stress were studied to provide a theoretical basis for expanding range annual production. Two varieties, ‘Tampico’ ‘Hypnotica Tropical Breeze’, used as test materials treated 1 d 2 at temperatures 35/30 ...

Under seasonal conditions, Polydesmus angustus individuals born in the first part of the breeding season have a 1-year life cycle and those born later have a 2-year life cycle (cohort-splitting). In this study, 249 juveniles from four early broods (born in midJuly) and four late broods (born in September) were reared under similar laboratory conditions, to test for possible maternal influences ...

In the present study, the effect of long-term salt stress (NaCl with 0, 0.1, 0.4 and 0.7 MPa)-temperature (25±2 oC and 35±2 oC) interaction on some antioxidant enzyme activities (ascorbate peroxidase, glutathione reductase and peroxidase) in six soybean cultivars (Glycine max L. Merr.) was investigated. The leaves of twenty-three-day old plants were used for the analysis of enzyme activities. S...

Carbon dioxide compensation values of mature leaves from 10 selections of citronella (Cymbopogon nardus [L.] Rendle) grown at 32/27 or 27/21 C day/night temperatures and three strains of lemongrass (Cymbopogon citratus [D.C.] Stapf. and Cymbopogon flexuosus [D.C.] Stapf.) grown at 8- or 15-hour photoperiods were measured in a controlled environment at 25 C. All leaves had low compensation value...
