摘要: In this paper, Wanjian 2090 without LOX-1 and LOX-2, a rice variety, was irradiated by ion beam to screen LOX-1/2 near-isogenic lines, which had the similar genetic background while the enzyme activities of either LOX-1 or LOX-2 were different. When these rice seeds were stored under both the accelerated ageing conditions for 12 days and the natural ageing conditions for 18 months, our results showed that the germination percentages of lines lacking both LOX-1 and LOX-2 were always higher than those either with LOX-1 or with LOX-2. In addition, rice lines with the presence of both LOX-1 and LOX-2 have the lowest germination percentages. The germination percentages of all genotype near-isogenic lines under two ageing conditions were correlated positively and significantly. (C) 2007 Published by Elsevier B.V.
