Abstract:
... Circumnutation, the helical movement of organs, has been observed in diverse species of land plants. Whether circumnutation arises purely from internal growth oscillations or as a response to exogenous forces such as gravity is a subject of active debate. By observing rice seedlings grown under microgravity at the International Space Station (ISS) and analyzing the agravitropic lazy1 mutant, Kobay ...

Abstract:
... The claim by González & Pabón-Moran (Brittonia 69: 176–185, 2017) that Psittacanthus (Loranthaceae) lacks polycotyly but has endosperm is shown to be based both on taxonomic misidentification and misinterpretation of seedling structure. The absence of endosperm and the presence of polycotyly in some species has been abundantly confirmed in the literature, much of the contents of which is ignored b ...

Abstract:
... Root system health is a key factor for seedling quality and it is a prerequisite for the proper growth of seedlings after out-planting. If the seedlings are moved to freezer storage too early in the season, roots can be damaged and thereby the quality of seedlings declines.
