Traits and Germination Test of Imported Carya illinoinensis Seed

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.
