pp: 244-250

Abstract:
Autumn-harvested achenes of Rosa corymbifera ‘Laxa’ can be successfully germinated in the following spring if pretreated with a proprietary compost activator and stored under controlled conditions. The pretreatment used is 10g moist achenes, 25g moist vermiculite, 0.5g * "Garotta" compost activator, before storing at 20° C for 12 weeks and then at 4° C for 12 weeks. A series of experiments is described which shows that the time of harvest, rate of compost activator, proportion of vermiculite and storage temperatures can all be varied within given limits.
