Pinus pinea: Stone Pine

open access: yesEDIS, 2006
Just as its name implies, Umbrella Pine has a broad, somewhat flattened round canopy, and the tree will ultimately reach 80 to 100 feet in height though it is more often seen at 35 to 45 feet tall and wide. The bright green, stiff, six-inch-long needles

In Vitro Adventitious Shoot Formation on Cotyledons of Pinus pinea [PDF]

open access: yesHortScience, 1998
Plant regeneration was obtained from adventitious buds induced in isolated cotyledons of Italian stone pine ( Pinus pinea L.). The best results for bud induction were obtained by using half-strength LePoivre medium with 4.5 μM 6-benzyladenine for 30 days.

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)
