Abstract

In the current study, the thermal stability of four selected Pinus L. species was analyzed in order to test the hypothesis that wethers pollen grain from same genus exhibit any variation on the species level. For this purpose Pinus sylvestris L., Pinus brutia Ten., and Pinus nigra Arn. were subjected to dynamic thermogravimetric analysis. The obtained thermograms the selected four Pinus species revealed no significant variation among their thermograms. For all the tested species five main degradation stages have been observed. The dTGmax values for P. griffithii Mc. Clelland, P. sylvestris, P. nigra and P. brutia were recorded at 442.6 °C, 439.1 °C, 442.2 °C, and 437.6 °C respectively. Considering the results from the current study it can be clearly concluded that the thermal stability of pollen grains from the same genus do not exhibit any significant variation
