Eleven non-polar sugars were detected in fresh seeds of
A. morrisonense, and the rank order of their abundance was
sucrose > fructose > myo-inositol > glucose > raffinose > mannose
(Table 5). Sucrose concentration in fresh seeds was 11.8 mg
(g DW)1 and it increased to 15.4 mg (g DW)1 during cold strati-
fication for 4 weeks and remained at this level through 12 weeks of
cold stratification. However, sucrose decreased to 5.9 mg (g DW)1
in radicle emerged seeds. Fructose decreased about four-fold
during cold stratification, and it continued to decrease when the
radicle emerged. Myo-inositol, glucose and mannose decreased
about 50% during cold stratification; however, they rapidly
increased three-to four-fold in radicle-emerged seeds. Raffinose
remained at the same level in fresh and cold-stratified seeds but
decreased about seven-fold as the radicle emerged. The concentration
of melibiose was 44 mg (g DW)1 in fresh seeds, and it was
significantly reduced to 23e26 mg (g DW)1 in cold-stratified and
radicle-emerged seeds. The concentration of trehalose remained at
about the same level, 44 mg (g DW)1
, in fresh, cold-stratified and
radicle-emerged seeds (Table 5).
