Comprehensive Evaluation of Saline-alkaline Tolerance of 45 Tomato Materials During Seed Germination
摘要
Abstract
In order to screen and evaluate the germplasm resources of tomato tolerant to salt and alkali,four salts(NaCl,Na2SO4,NaHCO3,and Na2CO3)were combined in a 1∶9∶9∶1 molar ratio to prepare saline-alkaline solutions of 10、30、50 mmol·L-1,facility distilled water as a control,which were used to investigate the effects of salt-alkali stress on seed germination across 45 tomato materials.Germination potential,germination rate,hypocotyl length,radicle length,germination index,and vigor index were measured,and the saline-alkali tolerance was evaluated comprehensively by principal component analysis(PCA)and membership function method.The results showed that saline-alkali stress significantly inhibited the germination ability of tomato seeds,but there were obvious differences for salinity-alkali tolerance among different materials.At 30 mmol·L-1 stress,the germination potential and germination rate of 45 materials decreased by 1.00-95.67 percentage points,and the germination rate decreased by 1.00-66.33 percentage points,which could well reflect the difference in salinity tolerance among tomato materials.The results showed that saline-alkali stress significantly inhibited the germination capacity of all tomato materials,but the salt tolerance of different materials were significant differences.Ten saline-alkaline tolerant tomato materials were identified,including 2 wild tomato materials(W4,W3),and 8 S:lycopersicum(BIG)materials(B28,B13,B17,B36,B12,B25,B37,B39).The results of this study provide a theoretical reference for the screening and utilization of germplasm resources of saline-alkali tolerant tomato.关键词
