Urban Farm DB summary

This study investigated the growth responses of eight medicinal plants, including Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata, under 70% shading and full sunlight conditions on a rooftop using artificial soil. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth under full sunlight, with Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, and Ligularia fischeri exhibiting low stress under full sunlight in August. While 70% shading was effective for Angelica gigas, Reynoutria japonica, and Aralia cordata, Angelica gigas and Reynoutria japonica grew better under full sunlight during summer.
