Abstract
SummaryIn the absence of special pre-treatments germination of achenes of three octoploid varieties of strawberry at 20°-25° C. was light-dependent and very variable. Values seldom exceeded 30% and were frequently much lower. Treatments with thio-urea and gibberellins A3 and A4 produced variable results, but failed to secure useful increases in percentage germination rates.Pre-chilling the imbibed achenes at 2° C. for six to eight weeks promoted germination to about 80% within 14 days of transfer to warm conditions.After chilling treatments the achenes eventually became largely independent of light for germination, but longer chilling periods were required for equivalent performance of dark-grown, compared to light-grown, achenes.
