摘要： A seedling-cutting apparatus includes a pair of arms (211, 212) that is to nip a portion of a stem of a seedling for grafting and that can be opened and closed and a blade (111) that is provided so as to be capable of reciprocating relative to the portion of the stem. At least one of the pair of arms (211, 212) includes a through hole (210) or a cutout that penetrates a portion of the arms (211, 212) along a direction in which the blade reciprocates. At least a portion of the through hole (210) or the cutout faces the portion of the stem and at least a portion of the blade (111) moves through the through hole or the cutout.

摘要： The present invention provides an organometallic complex having a high quantum efficiency even in a polymer thin film as a emitting material for organic electroluminescent (EL) element. The present invention relates to an organoiridium complex for an organic electroluminescent element represented by the following Formula; wherein a C-N ligand including two atomic groups (A 1 , A 2 ), and a ²-diketone) ligand in line symmetry having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The organoiridium complex of the present invention has a high quantum efficiency even in a polymer thin film with respect to green to yellow electroluminescence. (In the aforementioned Formula, R 1 , R 2 , and R 3 are each a tert-butyl group or a hydrogen atom, and have at least one tert-butyl group; they may bond each other to thereby form a saturated hydrocarbon ring, when having two tert-butyl groups; A 1 , A 2 are each an unsaturated hydrocarbon ring, at least one is a single ring, and at least one is a heterocyclic ring.)
