采用水培法对高丹草及亲本进行发芽期耐盐性评价。结果表明:盐胁迫对种子发芽起到明显的抑制作用;标准差系数赋予权重法、5级评分法能够准确评价耐盐性;明确了胚芽长、胚根长、幼苗生物量、发芽率等可作为耐盐性测定指标;耐盐性强的亲本组配的杂交种耐盐性也较强;NaCl溶液耐盐性评价方法简单,结果准确;不同材料耐盐性强弱顺序为冀草1号、S2006、冀草2号、天农2号、冀草3号、S76、HB623B、HG5B、H239B;按不同种分析,高丹草耐盐性最强,苏丹草次之,保持系较差。
採用水培法對高丹草及親本進行髮芽期耐鹽性評價。結果錶明:鹽脅迫對種子髮芽起到明顯的抑製作用;標準差繫數賦予權重法、5級評分法能夠準確評價耐鹽性;明確瞭胚芽長、胚根長、幼苗生物量、髮芽率等可作為耐鹽性測定指標;耐鹽性彊的親本組配的雜交種耐鹽性也較彊;NaCl溶液耐鹽性評價方法簡單,結果準確;不同材料耐鹽性彊弱順序為冀草1號、S2006、冀草2號、天農2號、冀草3號、S76、HB623B、HG5B、H239B;按不同種分析,高丹草耐鹽性最彊,囌丹草次之,保持繫較差。

Experiment was conducted to evaluation of NaC1 stress on Sorghum bicolor× Sorghum sudanense at seed germination stage based on water culture. The results indicated that the germination of seeds was markedly inhibited under NaC1 stress;The methods of standard deviation coefficient allocation weighted and the five level grade could be evaluate NaC1 stress on Sorghum bicolor×Sorghum sudanense accurately. And bud length, root length, seedling biomass and germination rate could be evaluation index, the sequence of salt tolerance from strong to weak was as follows.JC-001, S2006, JC-002, TN-002 ,JC-003, HB623B, HG5B, H239B. Salt tolerance of Sorghum bicolor×Sorghum sudanense was the highest while that of Sorghum sudanense was between Sorghum bicolor×Sorghum sudanense and Sorghum bicolor.
