Golgi vesicles and pollen tube walls isolated from germinating Petunia pollen were chemically analysed. The protein: lipid ratio of the Golgi vesicles was 70:30. The total carbohydrate contents of the Golgi vesicles and pollen tube wall were found to be 7.2% and 61 % of the dry weights respectively. The alkali insoluble material of the pollen tube wall contained 6% of the total carbohydrate; this material has been found to be cellulosic in nature. The sugar composition of the polysaccharides extracted from the Golgi vesicles and the tube wall is presented and discussed.
