Research objectives:
Pollen analysis of Ambrosia artemisiipholia L. 2014-
Aim of the research: quantitative and qualitative examination of pollen, examination of microscopic microorganisms of pollen and its ecological and allergic role. The research team consists of 4 people, headed by: Dr. Donát Magyar (Public Health Service)
Description and results of research:
Besides the atmosphere concentration of ragweed pollen and its role in allergies, the connection between the environmental pollution and the augment of the pollen indicated allergic reactions is not a negligible factor. In our study we wanted to find if morphological changes can be observed in different parts of the plant / root, stem, leaves, flower and pollen during copper and cadmium treatment and to what extent.. In the tests hydroponic experiments were carried out. The morphology of pollen grains were studied with the help of an electron microscope and a stereo microscope.
The length of the ragweed root, the stem and the inflorescence axis were significantly reduced compared to the control during copper treatment.
Dry and wet values of the plant are smaller compared to the control in all plant organs in both copper and cadmium treatment. The pollen morphology was changed during cadmium and copper treatment. The average number of deformed pollen in the control ragweed samples is less than 10 %. More than 40 % of the pollen grains are deformed in cadmium treated plants. Pollen deformation exceeds 50 % in copper treatment.
In areas exposed to strong pollution the morphological changes of ragweed pollen could also be observed. In pollen samples from ruderalia the average number of deformed pollen is 40 %. Values were significantly higher in the samples coming from industrial and agricultural areas. The quantity of the deformed pollen correlates with the result of the vitality test. The prolin concentration of pollen grains from ruderalia was the lowest.
Our results draw attention to the environmental impact of pollen morphology, it affects the vitality of pollen grains, which can modify allergic symptoms.
