Both MHSTs depended on the developmental stage at the time of the shock,and were lower at the early cleavage and blastopre closing stages than at any of the others.Namely,the eggs at these two stages were the most susceptible to the short-term thermal shock.}, pages = {91--95}, title = {キュウセン Halichoeres poecilopterus 卵の発生に伴う高温耐性の変化}, volume = {5}, year = {1991} }
