Short Days

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)

Ocean warming has facilitated the extension of Heliocidaris crassispina to Oga Peninsula, Japan, where the native species Mesocentrotus nudus has disappeared. To verify the temperature impacts on the physiology and behaviour of the two species, we reared small sea urchins at the increasing/decreasing temperature rate of 2.5°C week-1. The righting response, lantern reflex, gonad and gut carbon (C) and nitrogen (N) contents, and feeding rate were investigated. The high and low temperature limits of H. crassispina were 33.3°C and 3.9°C, respectively, which were higher than those of M. nudus. The optimal temperature ranges for behaviour and feeding in H. crassispina were 10.3–31.0°C and 10.3–33.4°C, respectively, which were higher than those in M. nudus. Feeding rates decreased significantly in both species when the temperature approached the high or low temperature limit, but the gut C and N contents of were not greatly affected. At 26–31°C, the feeding rate significantly decreased in M. nudus but not in H. crassispina, which may explain the replacement of M. nudus by H. crassispina in the Oga Peninsula.
