1967~1970年9~1月,在有珠湾利用每年3月采的条斑紫菜单孢子体冷冻保存的母藻进行了各种方式的采苗及养成试验。结果如下:(1)冷冻母藻的单孢子和壳斑藻的壳孢子不同,它的放散不受时期和时间的限制,赋活1~2天就能长时期放散。但不能在同一时间大量放散,即便给予空气搅拌的刺激,也不会突然大量放散。还有放散的孢子并不完全是单孢子,而含有果孢子及不萌发的孢子。(2)比较一下空气搅拌采苗、悬浮采苗及防护袋采苗的效率,可以看出防护袋采苗的效率最高,每厘米网线上有发芽体30棵,36尺网片用0.37克母藻就够了。从单孢子放散特性来看,用冷冻保存的母藻采苗,在海上自然条件下时间长一些较好。(3)从紫菜养成的情况看来,1968年的生长密度由于二次芽的出现,网上的紫菜苗显著地增加了,藻菜长度也达到10厘米左右。1969年度由于采苗较晚,加上腐烂病的影响及初期露空时间不妥当,二次芽增加不多,藻体没有长大就结束了。
From 1967 to 1970, from January to July 1970, a variety of seedling acquisition and culture experiments were carried out in a population of algae that had been frozen and preserved in Pseudomonas aeruginosa collected in March each year in Zhuwan. The results are as follows: (1) The single spore of the frozen algae is different from the shell spore of the shell-forming algae, and its emanation is not limited by the period and the time, and can be released for a long time after being activated for 1 to 2 days. However, it can not be dissipated in large quantities at the same time, and even if the air-stirring stimulus is given, it will not suddenly dissipate in large quantities. There are scattered spores are not completely single spore, but contain spores and non-germination of spores. (2) Compare the efficiency of air-pickling seedling, seedling pickling and protective bag picking in air, it can be seen that the protective bag picking seedling has the highest efficiency. There are 30 sprouts per centimeter, and 0.37g Algae is enough. From the monospore release characteristics, using cold preservation of algae seedlings, natural conditions at sea for a longer time is better. (3) From the case of cultivated seaweed It appears that the growth of the density in 1968 due to the emergence of secondary buds, the online seaweed significantly increased, the length of the cauliflower also reached about 10 cm. 1969 due to the late seedlings, coupled with the impact of rot disease and the initial open time is not appropriate, little increase in secondary buds, algae did not grow up to an end.
