Angiopteris somae (Hayata) Makino & Nemoto is an endemic and endangered fern in Taiwan, facing population decline due to inadequate habitat protection, plant competition, and illegal collection. Ex situ conservation is urgently needed, and stipule vegetative propagation is a practical method for this purpose. However, the low stipule production limits propagation efforts. This study investigated the correlations between phenotypic traits and sprouting parameters, finding no significant links between plant age or size and their sprouting ability. Juvenile stipules located near the apex of rhizomes produced more sprouts than those situated near the base. Additionally, deceased stipules were observed to be smaller and lighter. Sprout number did not correlate with stipule size, nor did the time for sprouting relate to age or size of the stipules. These findings can guide conservationists in selecting stipules with higher potential for sprout production, ultimately helping to minimize collection and protect mother plants during ex situ conservation. |
