Kinetics of growth, development and absorption of nutrients in stone pine (Pinus pinea L.) cultivated in the presence of NaCl

open access: yesBrazilian Journal of Biology, 2022
The aim of the present work was to evaluate and analyze the growth and mineral nutrition response of stone pine (Pinus pinea L.) seedlings, an economically important forest species. We analyzed the salinity effects on the kinetics of growth, development,

Gravitational stress on germinating Pinus pinea seeds

open access: yesComptes Rendus. Biologies, 2003
In the germination of lipid-rich seeds, the glyoxylate cycle plays a control role in that, bypassing the two decarboxylative steps of the Krebs cycle; it allows the net synthesis of carbohydrates from lipids. The activity of isocitrate lyase, the key enzyme of the glyoxylate cycle, is an indicator of the state of seed germination ...

Modelling Pinus pinea forest management to attain natural regeneration under present and future climatic scenarios [PDF]

open access: yes, 2013
Natural regeneration-based silviculture has been increasingly regarded as a reliable option in sustainable forest management. However, successful natural regeneration is not always easy to achieve. Recently, new concerns have arisen because of changing

A silviculture-oriented spatio-temporal model for germination in Pinus pinea L. in the Spanish Northern Plateau based on a direct seeding experiment [PDF]

open access: yes, 2013
Natural regeneration in Pinus pinea stands commonly fails throughout the Spanish Northern Plateau under current intensive regeneration treatments. As a result, extensive direct seeding is commonly conducted to guarantee regeneration occurrence.

Multisite Inhibition of Pinus pinea Isocitrate Lyase by Phosphate [PDF]

open access: yesPlant Physiology, 2000
Abstract Our results show that the phosphate ion is a nonlinear competitive inhibitor of Pinus pinea isocitrate lyase. In addition, this compound induces a sigmoidal response of the enzyme, which usually exhibits standard Michaelis-Menten kinetics. This peculiar behavior ofP. pinea isocitrate lyase could be explained by a dimer (two-site)

Therrya fuckelii and other fungi on stems and branches of Pinus sylvestris following lightning damage

open access: yesActa Mycologica, 2013
The evidence-based hypothesis is presented that the stems and branches of Pinus sylvestris injured by lightning strikes are colonized first by Therrya fuckelii and successively by Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella ...
