| Abstract: | Stylar soluble proteins were extracted from the whole style of pear cultivars differing in self&;#1048577;incom patibility ( SI) strength and were separated by isoelectricfocusing polyacrylamide gel electrphoresis ( IEF&;#1048577;PAGE) and each S-glycoprotein content was quantif ied by an image analyzer. Total S-glycoprotein ( sum of two allelic&;#1048577;linked S glycoproteins) content differed among cultivars. The cult ivars which were strong SI, weak SI and sel&;#1048577;compatibility contained &;#1048578;1. 3 ng, 0. 7 - 0. 9 ng, and 0. 7 ng of S&;#1048577;glycoprotein per &;#1048577;g of stylar soluble protein, respectively. S-allele linked glycoprotein content differed greatly in various S-genotypes. Furthermore, the S-glycoprotein content was even different in cultivars with the same S genotype. |
