许多紫菜品种,包括东亚国家大量栽培的品种,能够产生像单孢子一样的中性孢子或无性孢子。配子体形成的单孢子构成了另一个生长周期,此期仅有单倍体阶段,有别于一般单倍体与双倍体交替的生长周期。因此单孢子作为种子来源在栽培生产上得到广泛应用,并且作为一种培养技术在陆地上 Many varieties of seaweed, including cultivars cultivated in East Asian countries, produce neutral spores or asexual spores like monosporants. Single sporozoites formed by the gametophyte constitute another growth cycle, this period only the haploid stage, different from the general cycle of alternating haploid and diploid. Therefore, the single spore as a seed source in the cultivation and production has been widely used, and as a cultivation technique on land
