摘要：

Ultrastructural alterations of dictyosomes after treatment with monovalent ionophore, monensin, were studied in pollen tubes of Malus domestica Borkh. The cisternae of dictyosomes in pollen tubes, grown in the presence of 125 nm monensin for 60 min, appear dilated and the interval between two consecutives is enlarged. These changes are stronger towards the pollen tube apex. The number of large vesicles is decreased. In pollen tubes treated with 125 nM monensin for 120 min cisternae are swollen. Unlike the small vesicles, the large ones become hardly recognizable and do not react or react weakly to the polysaccharide test.
