Investigation of plant systemic organoseleno compounds. V. Effects of the derivatives of selenomorpholine on the selenium content of garlic.

摘要

The availability of inorganic and organic forms of selenium (Se) to garlic was studied by supplying selenium twice during the life cycle under field conditions. Most of the organic seleno compounds were more effectively taken up by garlic than sodium selenite. When sprayed with 50 mL 100 ppm O,O-diethyl-(N-selenomorpholinyl)phosphonate, the selenium content of the garlic bulb increased from 0.138 ppm to 1.734 ppm. When sprayed with 3-butyl selenomorpholine hydrochloride and 4-amino benzenesulfonyl selenomorpholine hydrochloride, the selenium content of the garlic leaf increased from 0.240 ppm to 7.32 ppm and 6.03 ppm, respectively.
