摘要
试管模拟盐碱土对30个马铃薯品系材料进行了耐盐碱筛选。结果表明，当培养基中总盐含量达到0．1％时，耐盐碱能力最差的品系就开始死亡，如144－4、3－2、65等品系，而耐盐碱能力强的品系，即使总盐含量达到0．4％，植株仍能存活，如品系I、131、31等。耐盐碱能力强的品系，其培养基的pH值在培养过程中都逐渐下降，到取样时均达到了适宜植株生长的范围。这说明，耐盐碱的植株能够向土壤中分泌大量H＋。
Thirty potato clones were screened for their tolerance to salts in vitro. When the total salt concentration in medium was 0.1 %, the clones, such as 144-4, 3-2 and 65, began to die,but other clones , such as I, 131 and 31, which shown tolerance to salts, can still be alive even when the total salt concentration was up to 0. 4 %. The pH value of the media in which the tolerant clones were cultured, was lowered. This result suggest that the tolerant potato plants secrete H + into soil.
