Localization of ginsenosides in Panax quinquefolium root tissues

Acta Agrobotanica, 2012
We carried out histochemical studies to find the localization of ginsenosides in roots of Panax quinquefolium cultivated in Poland. We performed an anatomical study on the structure and localization of secretory canals on the cross section of 4-year-old ...

Panel statement on young pine plants used for afforestation or reforestation as pathway for pinewood nematode (PWN) Bursaphelenchus xylophilus

EFSA Journal, Volume 24, Issue 8, August 2026.
Abstract Pinewood nematode (PWN) (Bursaphelenchus xylophilus) is a destructive pest of Pinus trees worldwide which depends for transmission on the cerambycid insects of the genus Monochamus. EFSA was asked to assess the potential role of young host plants for afforestation or reforestation planting as a pathway for PWN. According to legislation (EU COM/

Evolutionary origins of secondary growth - the periderm perspective: Integrating evidence from fossils and living plants [PDF]

Periderm is a structural feature with roles in protection of inner plant tissues and wound healing. Knowledge of periderm occurrences in the fossil record and living lineages outside the seed plants is limited and its evolutionary origins remain poorly ...

Permeability of Periderm and Cuticular Membranes to Alkali Cations

, 1995
The rates of penetration of alkali cations through isolated potato periderm and pear fruit cuticular membranes as a function of pH and the external solution concentration were determined. Steady-state rates were measured using a diaphragm diffusion cell,
