【摘要】 用包埋-脱水法在常温和常低温下保存条斑紫菜自由丝状体,探讨了温度、光(暗)和含水量等因素对存活率的影响。结果表明,条斑紫菜自由丝状体在常温或常低温下都可以保存6个月并保持较高的存活率;其中,4℃(暗)保存的最高存活率达到71.5%;而且保存后的丝状体的生长力达到了保存前的水平。包埋-脱水法操作简单,无需贵重设备,在藻类种质保存中有广阔的应用前景。更多还原

【Abstract】 The free living conchocelis of Porphya yezoensis Ueda were preserved in normal temperature and normal low temperature by using encapsulation-dehydration method.The facters influencing the algal viability,such as different temperature,illumination intensities and the water content of beads were studied.The results showed that the conchocelis were stored for 6 months under normal temperature and normal low temperature and the high viability were obtained.,the algae viability reached the most point at 71.5 % in the temperature of 4℃(dark),furthermore,the algae viablity of the conchocelis preserved could reach the normal level.The method of encapsulation-dehydration simplifies the operation procedure and do not need expensive equipments,so it is a potential method for preservation of the algae.更多还原
