Study on seedling techniques of Paris polyphylla var. yunnanensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>To study the effect of some factors (temperature, sowing time, covering-soil depth, plastic film ) on seed emergence of P. polyphylla var. yunnanensis.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>Above results provide seedling techniques of P. polyphylla var. yunnanensis.</p>
