multivariate analysis - Opis:
- The morphology and variability of pollen of Rosa pendulina L. were studied. The material came from 10 native localities of this species. 300 pollen grains were examined. It was established that the diagnostic features of pollen grains of R. pendulina L. were: an elongated, narrow operculum, a poorly developed exine sculpture, long ectocolpi (a low value of the apocolpium index), and the predominance of grains elongated in shape. The results obtained usually correspond to data supplied by other palynologists. A statistical analysis of 10 quantitative grain characteristics showed their variability to be rather low. The highest variability was found to occur in two traits connected with d (the distance between the apices of two ectocolpi). Statistical studies revealed dependences among the grains from the 10 analysed localities
