摘要:
 研究了对温度、盐分、干旱胁迫和果翅对无叶假木贼种子萌发的影响。结果表明,无叶假木贼种子在不同温度梯度下均有较高的萌发率,这说明低温仅仅抑制了无叶假木贼种子的萌发速率,但并不影响种子的最终萌发率。随着盐分浓度的增高,种子的萌发率降低,在>12 g/L的NaCl溶液中种子的萌发率显著下降,将在盐溶液中处理过未萌发的种子用蒸馏水冲洗后,萌发恢复率较高。随着PEG溶液浓度的增加,无叶假木贼种子萌发率显著降低,复水后种子萌发率恢复正常,说明高浓度的PEG溶液对无叶假木贼种子萌发具有抑制作用。具翅种子的萌发率较低,表明果翅对种子的萌发有抑制作用,去除果翅可以促进种子的萌发。该研究对减缓荒漠化,改善生态环境具有重要意义。
Abstract:
 Influences of temperature,salinity,drought and winged perianths on the germination of Anabasis aphylla seeds were examined.The results showed that the seeds could germinate in different temperatures set in the study,indicating that low temperature only inhibited the seed germination but had no effect on the final germination rate.The germination percentage decreased with the increase of NaCl concentration,the germination decreased significantly when the concentration of NaCl solution was higher than 12 g/L.When the incubated seeds treated in NaCl solution were transferred to distilled water,the recovery rate of the germination was high.With the increase of PEG concentration,seed germination rate decreased significantly,after the water recovery test,the seed germination rate returned to normal,indicating that high concentration of PEG solution inhibited the seed germination.Wing perianths exhibited mechanical inhibition on seed germination.
