Effect of temperature and scarification on seed germination of Conanthera spp. (Tecophilaeaceae)

Abstract: The Chilean endemic genus Conanthera is comprised of five species of herbaceous cormous geophytes. They have ornamental value due to their bell-shaped flowers, which are blue, violet or white. Previous germination studies of Conanthera campanulata and Conanthera trimaculata were carried out at 22 °C, and manual mechanical scarification improved germination. Based on these results, it was suggested that physical dormancy is present in the non-scarified seeds. However, an improvement in germination after scarifi… Show more

“…The predominant form of scarification is mechanical scarification, wherein the testa, or seed coat, undergoes physical manipulation to enable the ingress of moisture and air. Various approaches are utilized in this process, encompassing the abrasion of seed coats with tools such as metal files, sandpaper, knives for nicking, gentle hammering for cracking, or any method that weakens or opens the seed coat [34][35][36][37][38][39]. This technique finds extensive application within the realms of horticulture and agriculture, serving as a fundamental method to facilitate the germination of seeds encased in rigid or impermeable seed coats.…”
