- Abstract:
- Using 32 collected lily germplasm from China and overseas as experimental materials,effects of medium-term plant height,SPAD value,leaf nitrogen content,mature plant height,stem diameter,flowers per plant,and period from sowing to flowering of lily germplasm on alkali stress (pH 7.8) were studied under field environment.It would provide a reference for the comprehensive evaluation of alkali tolerance of lily germplasm during the whole growth period.The results showed that 32 lily germplasm could be clustered into 2 categories,Category I was alkali-tolerant lily germplasm with 19 germplasm,and category II was alkali-sensitive lily germplasm with 13 germplasm.The variation range of medium-term plant height among the 19 lily germplasm was 5.12-22.38 cm,the average was 12.16 cm,the standard deviation was 4.17,and the coefficient of variation was 34.33%.The coefficient of variation for flowers per plant was 51.28%,followed by the medium-term plant height,and the minimum coefficient of variation for period from sowing to flowering was 4.21%.Combining weighted subordinate function value alkali tolerance evaluation method with common factor loading matrix alkali tolerance evaluation method,alkali tolerance of ‘Suncrest’‘Honesty’ and ‘Fangio’ among 19 lily germplasm were strong,followed by ‘Leiyi 1’ and ‘Eyeliner’‘Lilium pumilum DC’‘Lilium regale Wilson’ and ‘Lilium davidii var.unicolor Salisb.’ had weak alkali tolerance.The lily germplasm with both the first common factor and the second common factor at the same time in the two-dimensional sorting analysis mainly included ‘Suncrest’‘Honesty’‘Eyeliner’‘Leiyi 1’‘Red alert’ and ‘Detroit’.SPAD value,leaf nitrogen content,medium-term plant height,mature plant height,and period from sowing to flowering could be used as important indexes for evaluation of alkali resistance during the whole growth period of lily germplasm.The weighted subordinate function value alkali tolerance evaluation method and common factor loading matrix alkali tolerance evaluation method could be used as a comprehensive evaluation method for the alkali resistance of lily germplasm during the whole growth period.
