Diagnosis of ink disease of chestnut by molecular identification of associated phytophthora species [PDF]

, 2005
For diagnostic proposes of ink disease, chestnut orchards with symptoms of decline or sudden death of trees were sampled by soil baiting techniques and selective agar media (P10VPH). Thirty-six Phytophthora isolates were obtained.

Free Sugar Profile in Cycads

Frontiers in Plant Science, 2014
The sugars fructose, glucose, maltose, and sucrose were quantified in seven tissues of Zamia muricata Willd. to determine their distribution throughout various organs of a model cycad species, and in lateral structural roots of 18 cycad species to ...

Nitrogen Fixation in the Coralloid Roots of Macrozamia Communis L. Johnson [PDF]

Australian Journal of Biological Sciences, 1965
Coralloid roots of Macrozamia communis have been shown by the isotopic method to fix nitrogen when they contain the endophytic blue·green algae. Immature coralloid roots devoid of the endophyte did not fix nitrogen. Coralloid roots from glasshouse-grown plants fixed 2· 7 times as much nitrogen when illuminated than they did in the dark and the IfiN ...

Symbiotic Nitrogen Fixation and the Challenges to Its Extension to Nonlegumes [PDF]

, 2016
Access to fixed or available forms of nitrogen limits the productivity of crop plants and thus food production. Nitrogenous fertilizer production currently represents a significant expense for the efficient growth of various crops in the developed world.

In vitro mycorrhization of micropropagated plants: studies on Castanea sativa Mill. [PDF]

, 2008
In vitro mycorrhization can be made by several axenic and nonaxenic techniques but criticism exists about their artificiality and inability to reproduce under natural conditions.

Encephalartos lanatus-associated bacteria and extracellular enzyme activities improve soil nutrition in nutrient-deficient grassland ecosystems

Scientific African
Encephalartos lanatus, commonly called ‘Olifants River Cycad’, is slow-growing and thrives in nutrient-deficient and acidic grassland soils. Like other Encephalartos spp., E.

Metal‐CO2 Batteries: By‐Product Challenges and Practical Pathways for Low CO2 Concentration Environment

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal‐CO2 batteries have recently emerged as an intriguing class of energy storage and conversion devices that simultaneously utilize and manage carbon dioxide. Originating from studies of CO2 contamination in metal‐air batteries, these systems have evolved into a distinct research direction, offering insights into CO2 electrochemistry and its
