Mature seeds of yellow lupine contained sucrose, raffinose family oligosaccharides (RFOs), and galactosyl cyclitols as major soluble carbohydrates. The study showed that RFOs dominated in lupine seeds (16 % DW). The disappearance of both types of α-d-galactosides in germinating lupine seeds was strongly inhibited by the presence of jasmonic acid–methyl ester (JA–Me) at a concentration of 10⁻³ M in the incubation medium. JA–Me inhibited the activity of α-d-galactosidase (fraction I) during seed germination. Anatomical studies of lupine roots have shown certain cell structure differences between control and JA–Me-treated seedlings. The cross-sections of plant roots treated with JA–Me showed a characteristic folding of the cell walls in all root tissues, starting from the rhyzodermis, cortex and vascular cylinder. In water-treated (control) plants, the cell walls were rounded with no folding.
