NaCl 胁迫对低植酸小麦突变体材料种子萌发特性的影响
The Effect of NaCl Stress on Seed Germination of Wheat Mutants with Low Phytic Acid
摘要
Abstract
Phytic acid (PA)is naturally stored in seeds of a wide range of cereal and legume crops.In recent years,it has become a research hotspot to breed crop varieties with low phytic acid (LPA)by using mutagenesis technology.In the current research,we ob-tained nine LPA wheat mutants by 60 Co -γradiation,and then assessed their salt tolerance using a germination test with different con-centrations of NaCl.As a result,their seed germination was promoted at 0.5% NaCl concentration,but substantially inhibited at 1.0% and 1.5% NaCl concentrations;all tested NaCl concentrations produced an inhibitory effect on seedling growth and primary root growth.Among the nine LPA wheat mutants,four (lp14,lp49,lp50,and lp55)showed higher salt tolerance,which may be used as materials for breeding wheat varieties with salt tolerance in the future.关键词
