bibo:abstract
  • Lower field germination was observed in lipoxygenase- lacking soybean genotypes. This study was performed to nderstand seed-related traits after accelerated aging in response to planting date of soybeans. Two soybean cultivars, Jinpumkong (null lipoxygenase-2, 3) and Jinpumkong 2 (lacking lipoxygenase-1, 2, 3) were evaluated for germination, and were compared with the cultivar, Taekwangkong containing lioxygenase-1, 2, 3 isozymes. Greater seed coat cracking was shown in Jinpumkong and Jinpumkong 2 than Taekwangkong. Regardless of soybean genotypes, earlier planting resulted in greater seed coat cracking. After accelerated aging, seed fracturability and hardness of Jinpumkong and Jinpumkong 2 were lower than those of Taekwangkong. There was significant difference in germination percentage among soybean genotypes in response to planting date. Seeds obtained from late planting showed better germination ability Accelerated aging resulted in lower germination percentages of Jinpumkong and Jinpumkong 2 than that of Taekwangkong, and showed higher electric conductivity in Jinpumkong and Jinpumkong 2 than Taekwangkong. After accelerated aging at 40℃ for thirty five days, germination percentages of Jinpumkong and Jinpumkong 2 were lower than that of Taekwangkong. Electric conductivity was increased continually as accelerated aging time became longer, and Jinpumkong and Jinpumkong 2 showed higher electric conductivity than Taekwangkong. Even though there were significant genotype differences in seed traits, further studies are needed to determine whether seed lipoxygenase ability is associated with germination ability.
