Abstract:

【Objective】 In order to explore the tolerance of rapeseed under saline-alkali soil stress in Xinjiang, screen out salt-tolerant varieties that are more in line with actual production, and establish a salt tolerance identification system for rapeseed under saline-alkali environment in this region. 【Methods】 In this study, the pot soil culture method was used to identify the salt tolerance of rapeseed germplasm resources with strong salt tolerance screened in the previous experiment with the proportion of T1, T2, T3, T4 and T5 in southern Xinjiang saline soil. The salt tolerance of the whole growth period was identified, and the optimum concentration of salt tolerance screening for rapeseed under saline-alkali soil was determined to be. The concentration of saline soil was used to identify 300 rapeseed varieties, and the germination rate was determined. According to the growth situation, 6 rapeseed germplasm resources with strong salt tolerance were screened out, and salt tolerance gradient identification was carried out according to different proportions. The ion content was determined, and the salt tolerance of the varieties was classified by the germination rate of rapeseed under saline soil. 【Results】 The results showed that the optimum concentration of T3 for the identification of salt tolerance of rapeseed during germination under saline soil in Xinjiang was determined. In addition,the ion content was determined, and the salt tolerance of rapeseed varieties was classified according to the germination rate of rapeseed under saline soil. 【Conclusion】 In this experiment, the salt tolerance identification concentration of rape saline soil is determined. According to this concentration, 300 rapes are divided into four categories: strong, medium, weak and extremely weak by germination rate, including 10 salt-tolerant varieties, 75 medium salt-tolerant varieties, 91 sensitive salt varieties and 24 extremely sensitive salt varieties. According to the observation of the whole growth period, 6 varieties with strong salt tolerance are determined, and the salt tolerance identification experiment is carried out in the whole growth period. According to F = 0.4 Z + 0.3 H + 0.3 Y, the salt tolerance was classified. The Z <0.3 of CJLZS219266 and CJLZS219310 was grade IV, saline-alkali sensitivity. The Z value 0.3 ≤ Z <0.5 of CJLZS219346, CJLZS219181 and CJLZS219172 is grade III, which is not tolerant to saline-alkali. The F > 0.7 of CJLZS219368 is grade I strong saline-alkali resistance.

摘要:

【目的】探究油菜在新疆盐碱土胁迫下的耐受性,筛选出更符合生产实际的耐盐品种,在新疆盐碱环境下建立油菜耐盐性鉴定体系。【方法】采用盆栽土培法,按T1、T2、T3、T4和T5比例的新疆南疆盐土,筛选出的10份耐盐性强油菜种质资源,鉴定其芽期和全生育期的耐盐性,确定盐碱土下对油菜筛选耐盐的最佳浓度,使用该浓度盐土鉴定300份油菜品种,测定其发芽率,根据生长情况综合筛选出耐盐性强的6份油菜种质资源,按不同比例对其进行耐盐梯度鉴定,分析其离子含量,以盐土下油菜的发芽率将品种耐盐性分类。【结果】确定油菜盐土的耐盐鉴定浓度,按此浓度根据发芽率将300份油菜分为强、中、弱和极弱4类,其中10份耐盐品种,75份材料中等耐盐品种,91份敏盐品种,24份极敏盐品种。并根据全生育期的观察确定6份耐盐性并根据全生育期的观察确定6份耐盐性较强的品种,对其进行全生育期耐盐鉴定试验,根据F=0.4 Z+0.3 H +0.3 Y对其耐盐性进行综合评价,CJLZS219266、CJLZS219310的Z<0.3,为Ⅳ级,盐碱敏感性,CJLZS219346、CJLZS219181、CJLZS219172,为Ⅲ级,不耐盐碱;而CJLZS219368的F值>0.7,为Ⅰ级耐盐碱性。【结论】油菜在新疆盐土下萌发期耐盐性鉴定的最适宜浓度为T3浓度,明确其离子含量,以盐土下油菜的发芽率进行品种耐盐性分类。
