Abstract: Provided is a method for improving the yield of a harvested product of at least one plant selected from the group consisting of plants belonging to the families Solanaceae, Cucurbitaceae, Poaceae and Fabaceae. A method for cultivating at least one plant selected from the group consisting of plants belonging to the families Solanaceae, Cucurbitaceae, Poaceae and Fabaceae comprises applying a plant-vitalizing agent comprising an exogenous elicitor and an endogenous elicitor to a young seedling of the plant at least one time.

Abstract: Physiological processes in plants are regulated and reinforced, and crop vitality, yield, quality and post-harvesting storage life are improved. A plant vitalizer that includes a cellooligosaccharide is applied to the plants.

Abstract: In an analysis device, an auxiliary gas supplied from a compressor 1 is introduced from an auxiliary gas inlet 3 via a pipe 2 to a burner through a pressure regulator 5, a pressur meter 6, a pressure switch 7 and a connecting joint 8. On the other hand, a combustible gas supplied from a gas bomb 9 is introduced from a combustible gas inlet 11 via a pipe 10 to the burner through a first electromagnetic valve 12, a pressure regulator 13, a pressure meter 14, a needle valve 15, a second electromagnetic valve 16 and a connecting joint 17 and further via a tube.

Abstract: A light beam emitted by a hollow cathode lamp is concentrated on a central portion of an electrothermal sample atomizing apparatus by a concave mirror. The light concentrated on the central portion of the electrothermal sample atomizing apparatus is further concentrated on a central portion of a flame produced in a burner type sample atomizing apparatus by a lens. The light traveled through the burner type sample atomizing apparatus is condensed by a concave mirror, reflected by a flat mirror, and concentrated on an entrance slit of a spectroscope. Light outgoing through an exit slit of the spectroscope is detected by a photodetector.
