Research ArticleOpen accessIn the abstractGermination Study and Monitoring in the Nursery of Young Seedlings of Garcinia mangostana L.Haba Jean Florent, Dembele Ardjouma, Koffi Kouao Jean et al.Mangosteen tree (Garcinia mangostana L.) is a plant of the Clusiaceae family cultivated for its particular taste and for its excellent medicinal properties. However, the vegetative propagation of the plant by cuttings or grafting being difficult to achieve, seed germination remains the main means of production used. This study was therefore initiated with the aim of determining the influence of … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Sep 2021 · 7,445 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Physical Treatments on the Promotion of Seed Germination in Green and Giant FoxtailsInagaki Hidehiro, Sakakibara TakumiThe difficulty of breaking seed dormancy in Setaria (foxtail) species presents a problem in using them as model plants. In the present study, we observed the structure of the seed coat surface of two Setaria species, the green foxtail (Setaria viridis) and the giant foxtail (Setaria faberi), using an electron microscope. In addition, we tested the effects of physical treatment … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 25 Nov 2020 · 6,480 accessesView PDF Cite
