Osmotic adjustment in Pinus pinaster cuttings in response to a soil drying cycle

Leaf gas exchange and carbohydrate concentrations in Pinus pinaster plants subjected to elevated CO 2 and a soil drying cycle

Plants of maritime pine (Pinus pinaster Ait.) were acclimated for 2 years under ambient (350 μmol mol -1 ) and elevated (700 μmol mol -1 ) CO 2 concentrations ([CO 2]). In the summer of the second growing season, the plants were subjected to a soil drying cycle for 6 days. Drought reduced plant transpiration rate and net CO 2 assimilation rate (A) by about 80 %. Elevated [CO,] induced a s...

Resistance and response of Pinus pinaster seedlings to Hylobius abietis

Monitoring Response of a Few bZip Transcription Factors in Response to Osmotic Stress in Sunflower

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Intraspecific Variation in Pinus Pinaster PSII Photochemical Efficiency in Response to Winter Stress and Freezing Temperatures

As part of a program to select maritime pine (Pinus pinaster Ait.) genotypes for resistance to low winter temperatures, we examined variation in photosystem II activity by chlorophyll fluorescence. Populations and families within populations from contrasting climates were tested during two consecutive winters through two progeny trials, one located at a continental and xeric site and one at a m...

Sawing simulation of Pinus pinaster Ait

The paper deals with the sawing simulation of Maritime pine (Pinus pinaster Ait.) and is a report from a project aiming to increase the knowledge in how different raw material characteristics and sawing factors are affecting on the sawing yield of Maritime pine. The conversion was executed by an integrated optimising software system, WooDCIM® developed at VTT Technical Research Centre of Finlan...
