Photosynthesis in leaves, exposed to temperature change, was measured during spring to provide information for modeling of cropping systems for Chinese cabbage (Brassica campestris subsp. napus var. pekinensis) and radish (Raphanus sativus) in Jeju Island. The net photosynthetic rates (A) of Chinese cabbage and radish were depressed at temperatures above(More)
The Japanese American Cooperative Emulsion Experiments (JACEE) have recently carried out a series of Antarctic circumpolar long duration balloon flights (JACEE-10 ∼ JACEE-13) for the study of high energy elemental composition and energy spectra of cosmic ray particles. The total exposure factor of these experiments is 664 m 2 hr, which corresponds to about(More)
