进口美国山核桃种子性状及其发芽调控的研究

Traits and Germination Test of Imported Carya illinoinensis Seed

    摘要
  • 摘要: 以野生美国山核桃（Carya illinoensis）引进种子为试材，对其种子特性进行研究，并采用L9（34）正交试验方法进行催芽试验。结果表明，该种批果实较小，单果重平均值为2.68 g，纵径和横径分别为2.7、1.4 cm，出仁率42.8%；该种批含水率在13%左右，净度和优良度分别为99.9%和96%，但该种批发芽率仅41.3%。催芽试验结果表明，不同催芽处理对发芽率和发芽势的影响均存在显著性差异（p＜0.05），在已知组合中，A2B1C2（100 mg/L 的GA3处理3 d）的发芽率和发芽势最好，分别达86.00%和79.86%。极差分析优化可知，用200 mg/L的GA3浸种3 d催芽的发芽率效果最好。用于砧木的进口野生美国山核桃种源，在前一年秋季就应准备好种子，冬季进行低温沙藏层积，春季在播种前用200 mg/L的GA3进行浸种3 d催芽，可以获得高出芽率，并生长迅速。

     

    Abstract: Traits of imported wild Carya illinoinensis seeds were determined and germination experiments were conducted with L9 (34) orthogonal design. The results demonstrate that mean single nut weight was 2.68g, vertical and transverse diameter was 2.7 and 1.4cm with 42.8% kernel. Water content of seeds was about 13% with 99.9% of purity and 96% of quality seed percentage, but open field germination rate had only 41.3%. The experiment showed that different treatments had significant effect on germination rate and force. Treatment A2B1C2 (3 days treatment with 100mg/L of GA3) topped to 86.00% and 79.86% of germination rate and force. Range analysis indicated that treatment of 3 days with 200 mg/L of GA3 would have the best effect of germination rate.
