Pollen grain bioassay for environmental contamination biomonitoring

open access: yesActa 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

Preliminary studies on mustard taxonomy based on pollen morphology

open access: yes浙江大学学报. 农业与生命科学版, 2006
Pollen grains of 17 mustard subspecies were examined under scanning electron microscope. The result showed that the pollen shapes were nearly spherical, or spheroidal, or super-spheroidal from the equatorial view, depending on cultivars of mustard.
