Pollen morphology of Plantago species native to Poland and their taxonomic implications

Acta Societatis Botanicorum Poloniae, 2011
Pollen grains of 9 species of the genus Plantago (Plantaginaceae), including 8 taxa native to Poland, were observed under a light microscope and a scanning electron microscope. Descriptions of grain sculpture are illustrated only SEM micrographs.

Pollen grain bioassay for environmental contamination biomonitoring

Acta Biologica Slovenica, 2004
Pollen grain bioassay near some highways was performed in 45 plant species for identification of environmental genotoxic impact on naturally growing plants due to environmental traffic contaminants. A relationship between the duration of heavy traffic on

Differentiating apple sports by pollen ultrastructure : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science at Massey University [PDF]

, 1995
Cultivars are plants that form distinct, uniform and stable phenotypes. New cultivars can be protected by Plant Variety Rights (PVR) which allow the owner exclusive rights to the propagation and sale of the plant material.

A Mechanistic Study of Bio‐Based Nanotemplated Carbon Nanofibers Derived From Water Processable Lignin Blends for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
As‐spun carbon materials produced from Lignosulfonate, gelatin, and alginate, selected for water solubility, and ability to produce templated sustainable carbon nanostructures. Gelatin and alginate are sacrificial during thermal processing, allowing the production of engineered high surface area nanostructures, which are further characterized for ...
