Increased Ratio of Electron Transport to Net Assimilation Rate Supports Elevated Isoprenoid Emission Rate in Eucalypts under Drought     [PDF]

open access: yesPlant Physiology, 2014
Abstract Plants undergoing heat and low-CO2 stresses emit large amounts of volatile isoprenoids compared with those in stress-free conditions. One hypothesis posits that the balance between reducing power availability and its use in carbon assimilation determines constitutive isoprenoid emission rates in plants and potentially even their

Effect of Fruiting on Net CO2 Assimilation Rates of Peach and Nectarine Trees [PDF]

open access: yesHortScience, 1995
Growth of peach fruits is characterized by a double-sigmoid curve; two periods of rapid enlargement (stages I and III) separated by a lag phase (stage II). Seasonal net CO2 assimilation rates (NAR) were compared in leaves from fruiting and non-fruiting (deblossomed) trees of `Harrow Diamond' (early), and `Vivid' (mid-summer) peach (Prunus persica L ...

Correlation and path analyses in Maize (Zea mays L.) [PDF]

open access: yesElectronic Journal of Plant Breeding, 2014
A study was carried out on correlation and path coefficient analysis for eighteen characters on 45 hybrids, 15 inbred lines and 3 testers along with three checks at three locations and in two seasons (kharif 2012 and rabi 2012-13). The traits days to 50 %

Growth and morphological responses of Manna oak (Quercus brantii) seedlings to different light levels at nursery in the first growing year [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2012
Manna oak (Quercus brantii) is the most important tree species in Zagross region of Iran that faces lack of natural regeneration by seed. Forest managers suggest reforestation by seeds or seedlings as the main silvicultural practice, in order to ...

Modeling impacts of changes in temperature and water table on C gas fluxes in an Alaskan peatland [PDF]

open access: yes, 2015
Northern peatlands have accumulated a large amount of organic carbon (C) in their thick peat profile. Climate change and associated variations in soil environments are expected to have significant impacts on the C balance of these ecosystems, but the ...

Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]

open access: yes, 2013
Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...

Studying in vivo dynamics of xylem-transported 11CO2 using positron emission tomography [PDF]

open access: yes, 2020
Respired CO2 in woody tissues can build up in the xylem and dissolve in the sap solution to be transported through the plant. From the sap, a fraction of the CO2 can either be radially diffuse to the atmosphere or be assimilated in chloroplasts present ...
