  • Three lipoxygenase isozymes in soybean [Glycine max (L.) Merr.] seeds are thought to be a major contributor to lipid peroxidation and the generation of free radicals which may result in seed deterioration. This study was conducted to understand the relationship between seed lipoxygenase activity and germination and seed vigor in soybean. Two cultivars, Jinpumkong lacking lipoxygenase-2, 3 and Jinpumkong 2 lacking lipoxygenase-1, 2, 3 were evaluated for major traits of seed and germination, and were compared with the normal soybean Taekwangkong containing lipoxygenase-1, 2, 3 isozymes in seed. Seed protein and lipid contents of Jinpumkong and Jinpumkong 2 were similar to those of Taekwangkong. Jinpumkong and Jinpumkong 2 had more palmitic acid, linoleic acid, and linolenic acid in soybean seed than Taekwangkong, but had less stearic acid and oleic acid than Taekwangkong. Type I lipoxygenase activity (pH 9.0) of Jinpumkong lacking lipoxygenase-2, 3 was higher than that of normal Taekwangkong. Germination percentages of Jinpumkong and Jinpumkong 2 were lower than that of Taekwangkong. Electric conductivity was not significantly different in all cultivars. Using two soybean populations derived from the cross between normal Taekwangkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3, and between normal Pureunkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3, the effects of presence or absence of seed lipoxygenase activity on germination characteristics were evaluated. The F₂ derived from the cross between normal Taekwangkong(Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3 fitted to a expected segregation ratio of 9 : 3 : 3 : 1 (normal : lacking L-3 : lacking L-1 and L-2 : lacking L-1, L-2 and L-3), suggesting the tight linkage between the lx1 and lx2 loci, and <TEX>$$F_8$$</TEX> seeds derived from the cross between normal Pureunkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3 fitted to a expected segregation ratio of 1 : 1(L-1, L-2 : l-1, l-2 and L-3 : l-3, respectively). Germination percentages showed wide ranges but didn't differ among lipoxygenase isozyme types of F₃ and <TEX>$$F_8$$</TEX> seeds derived from the cross between normal Taekwangkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3, and between normal Pureunkong(Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3. After accelerated aging, germination percentages showed wide ranges but didn't differ among lipoxygenase isozyme types of F₃ and <TEX>$$F_8$$</TEX> seeds derived from the cross between normal Taekwangkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3, and between normal Pureunkong (Lx1Lx2Lx3) and Jinpumkong 2 (lx1lx2lx3) lacking lipoxygenase-1, 2, 3. Presence or absence of lipoxygenase activity showed no effect on germination percentage. (rdf:langString) (en)
