栽培高粱(S.bicolor)是全球性的重要粮食及饲料作物。它相当耐盐,经常种植在盐碱地(Taylor 等,1975;Francois 等,1984)。另一种高粱属植物——约翰逊草(S,halepense),是一种有害的杂草,是潜在的生物能源作物,比栽培高粱更耐盐(Longenecker 等,1974)。这一结论是基于观察偶然的质量生长和存活性,但对二者的生长和耐盐性间的数量关系没做过比较鉴定。这可通过测定对盐浓度的生长反应程度,对比盐环境和对照环境中生物产量降低的表现,来比较它们的耐盐性(Maas 等,1977)。另外,借助对盐含量的相对生长反应 S. bicolor is a major global food and feed crop. It is quite salt tolerant and is often planted in saline soils (Taylor et al., 1975; Francois et al., 1984). Another sorghum, S, halepense, is a devastating weed that is a potential bioenergy crop that is more salt tolerant than cultivated sorghum (Longenecker et al., 1974). This conclusion is based on the observation of occasional quality growth and viability but no quantitative identification of the relationship between growth and salt tolerance. This compares their salt tolerance by measuring the extent of the growth response to salt concentration, comparing the reduction of biological yield in salt and control environments (Maas et al., 1977). In addition, with the relative growth of salt content of the reaction
