Abstract 

Objective

To shorten the duration of seed germinating, improve seed emergence and eventurally to establish a practical method for seeding of Paris polyphylla var. yunnanensis seed.

Method

To study the effect of some factors (temperature, sowing time, covering-soil depth, plastic film ) on seed emergence of P. polyphylla var. yunnanensis.

Result

The most suitable temperature for embryonic post-maturity and seed germinating is 18-20 degrees C. Paris seed could emerge in April when it was transfer to a low temperature 0-10 degrees C for 2-4 months after being treated under 18-20 degrees C for 3-4 months. For seed emergence, the best sowing time was before April. The suitable soil depth was about 1 cm. It is a better way to cover the seedling bed with black plastic film for improving the emergence percentage.

Conclusion

Above results provide seedling techniques of P. polyphylla var. yunnanensis.
