在从 Gracilariaasiatica Chang et 夏的果孢子的孢子石楠的早发展的学习在控制文化条件下面在室内被进行。除孢子石楠的正常开发以外,细丝状的复叶的新发展现象被观察。它由一个或二排房间组成,并且从基础圆盘的最外面的边缘发生了。发芽果孢子,果孢子或在大约 10%basal 磁盘上形成的二片细丝状的复叶的 Duringthe 早圆盘舞台。同时,年轻复叶从单个、联合的磁盘的中心稍微开始了到拱门;最近,直到 80% 的更细丝状的复叶出现在基础磁盘的边缘上。同时基础磁盘上的至少一正直的复叶 protuberated。通常,细丝状的复叶在一样的基础圆盘上与正常年轻孢子石楠在自我存在或共存形式展出了,并且单个房间从开发进一片新细丝状的复叶的细丝状的复叶分开了。Thisnew 现象在 G.asiatica 的早发展期间展出了一条唯一的区别小径,它将为在人工的孢子石楠托儿所的应用程序是潜在的。
Study on the early development of sporelings from carpospores of Gracilaria asiatica Chang et Xia was conducted indoors under controlled culture conditions. Besides normal development of sporelings, a new developmental phenomenon of filamentous frond was observed. It was composed of one or two rows of cells, and took place from the outmost brim of the basal disc. During the early disc stage of germinated carpospores, one or two filamentous fronds formed on about 10% basal discs. Simultaneously, young fronds began to arch slightly from the centers of single and coalescent discs; lately more filamentous fronds up to 80% appeared on the brims of basal discs. Meanwhile one or more upright fronds protuberated on the basal discs. Generally, filamentous fronds exhibited in self-existence or co-existence forms with normal young sporelings on the same basal disc, and single cell detached from filamentous fronds developed into a new filamentous frond. This new phenomenon exhibited a unique differentiation pathway during the early development of G. asiatica, which would be potential for the application in artificial sporelings nursery.
