Abstract

POLLEN ultra structure components and characters including; polar axe, equatorial axe, ratio of polar axe to equatorial axe, ridge diameter, pit surface area percentage and length of furrow were evaluated to test usefulness of each character for identification of PEAR species and cultivars. We used Scanning Electron Microscope (SEM) and image analysis software program. Statistical analysis of the data were conducted in a RCDB design. Results showed that polar axe, ratio of polar axe to equatorial axe and pit surface area were identified as useful means of identification. Result showed that there was no significant difference for equatorial axe among different PEAR cultivars and species. Thus, POLLEN equatorial axe was not a suitable character for identification of PEARs. On the other hand, polar axe, ratio of polar axe to equatorial axe, length of furrow and pit surface area percentage were all useful characters for identification of PEAR. All the PEARs for these characters were divided into 3 groups of maximum, moderate and minimum. POLLEN with a polar axe 43 to 45 micrometers in maximum, 39 to 43 in moderate and 36 to 39 in minimum were grouped. For the ratio of polar axe to equatorial axe a ratio of over 2 was located in maximum, 1.85 to 2 moderate and lower than 1.85 were grouped in minimum. For the germinal furrow, POLLEN with a length of germinal furrow of 37 to 43 micrometers in maximum, 36 to 37 in moderate and lower than 36 were grouped in minimum.
