Abstract: "The germination percentage of Rosa multiflora Thunb. achenes was
greatly increased when they were treated with 1% Driselase, a macerating enzyme,
for 36 hours. The seeds (corrected from needs) germinated more rapidly when the
achenes were treated with the enzyme for a longer period. Treatment with
Cellulase Onozuka improved seed germination at a lower concentration that did
Driselase. Pure preparations of pectinase and cellulose had effects similar to
treatment with the enzymes noted. Treatment with pectinase was more efficient
than treatment with cellulase.
These enzymes likely loosened the bond between cells along the suture of the
pericarp and forced the (corrected from th) pericarp to split.
