Abstract

Abstract:

Eighteen sweet potato varieties were selected as the test material. The control and treatment groups were established via saline soil cultivation in seedling stage. The treatment group received 200 mmol L ^-1 NaCl. Fourteen physical traits were observed in each treatment, which were fresh stem leaf weight, fresh root weight, dry stem leaf weight, dry root weight, relative leaf conductivity, F_v/F_m, SPAD value, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, proline content, root vigor, root Na ⁺ content, root K ⁺content, and Na ⁺/K ⁺ ratio. A comprehensive analysis of the salt tolerance of different varieties was conducted via correlation analysis, principal component analysis, clustering analysis, and stepwise regression of the salt tolerance efficiency of each index. Principal component analysis narrowed down the 14 single indexes in the salt-stressed seedling stage of sweet potatoes to five independent comprehensive indexes. Subordinate function analysis was conducted to obtain the comprehensive assessment value (D-value) of salt tolerance of different varieties in seedling stage. In clustering analysis, the 18 sweet potato varieties were divided into four salt tolerance types, including four salt-sensitive, three weak salt tolerant, seven moderate salt-tolerant, and four high salt-tolerant. On the basis of this division, stepwise regression method was used to establish a regression equation for salt tolerance assessment of sweet potatoes in seedling stage. Eight physiological indexes were selected (fresh stem leaf weight, fresh root weight, dry stem leaf weight, leaf SPAD value, SOD enzyme activity, MDA content, proline content, and Na ⁺/K ⁺ ratio) for the same assessment purpose. This paper presents the germplasm information for selection and breeding of new salt-tolerant sweet potato varieties. The results could serve as a basis for subsequent assessment of seedling stage salt tolerance of sweet potatoes and further studies on their salt tolerance mechanism.

Key words: sweet potato, seedling stage, salt tolerant, comprehensive assessment, identified index
