Evaluation of Salt Tolerance Among 41 Zoysia Accessions
摘要
Abstract
The purpose of the presen t study was to screen Zoysia germplasms of salt tolerance for breeding varieties planted in saline soils. 41 Zoysia accessions from east China were evaluated for salt tolerance using the soil culture method. Each accession was grown with 20 g/L NaCL ( experimental) or without exposure to NaCl (control). The mean dry weight of the root, shoot, and total body of the accessions relative to those of the non-treated controls were calculated after 60 d, and showed considerable diversity. Overall, the coefficients of the variation for the root, shoot, and total body weight of the salt-treated accessions relative to the non-treated controls was 44.86%, 31.09% and 31.51%, respectively. The classification based on subordinate function values revealed that 14 of the 41 accessions were tolerant to salt stress, 13 were moderately tolerant, and 14 were sensitive to salt stress. Z. matrella is the most salt tolerance, Z. sinica in the middle. The five most salt tolerance accessions were Z36, Z35, Z09, Z22 and Z05, the five most salt sensitive accessions were Z03, Z31, Z13, Z29 and Z43.关键词
