Abstract

Rooted cuttings of commercial cvs were grown to flowering at five temperatures and the the number of short days to flowering was recorded. The optimum temperature for rapid flowering varied between cvs. The number of days to flowering at the optimum temperature was not related to the delay in flowering caused by either high or low temperature. In many cvs the delay in flowering at low temperature was accompanied by a similar delay at high temperature. It was concluded that for the character 'time to flowering' genotypes should preferably be selected at low temperatures. If low temperature cannot be realized, only rapidly flowering genotypes should be selected. (Abstract retrieved from CAB Abstracts by CABI’s permission)
