以文冠果种子为试材,设置10种不同催芽方法,包括水浴加热、不同浓度的H2_SO_4、KNO_3、PEG-6000等试剂处理文冠果种子,诱导发芽后调查种子的发芽率、活力、发芽势等发芽参数,并对不同催芽方法进行了比较分析,筛选适合文冠果种子快速解除休眠的方法。结果表明:80℃水浴加热、4%KNO_3溶液、5%PEG-6000溶液、GA_3溶液、2%KNO_3溶液、10%PEG-6000溶液、4℃蒸馏水浸种、50%H_2SO_4溶液处理,均可不同程度的提高文冠果种子的发芽率,而高浓度H_2SO_4溶液处理对文冠果种子发芽有抑制作用;文冠果种子经80℃水浴加热10min处理可使发芽率提高到55.83%,为未处理的9.3倍。
Ten different germination methods were set up, including water bath heating, different concentrations of H2SO4, KNO3, PEG-6000 and other reagents for seed germination, germination rate, vigor and germination Potential and other germination parameters, and different germination methods were compared and analyzed, screening suitable for the rapid removal of the seeds of the fruit of the method of dormancy. The results showed that: 80 ℃ water bath heating, 4% KNO 3 solution, 5% PEG-6000 solution, GA 3 solution, 2% KNO 3 solution, 10% PEG-6000 solution, 4 ℃ distilled water soaking, 50% H 2 SO 4 solution treatment, , While germination rate of Xanthoceras sorbifolia Bunge seed was increased, whereas the treatment with high concentration H_2SO_4 solution could inhibit the seed germination of X. waruensis. The germination rate of Wen-guan sowing seeds increased by 55.83% at 80 ℃ for 10 min, 9.3 times.
