ABSTRACT
<p><b>OBJECTIVE</b>The experiments were conducted to study specialty of seed germinating, plant growing and developing and cultural practices of A. edgeworthii.</p><p><b>METHOD</b>The germinating and sowing test, growth habitants, photosensitive reaction of seedling from subterraneous seeds and above ground seeds on A. edgeworthii were studied in this experiment.</p><p><b>RESULT AND CONCLUSION</b>The results indicated that (1) The water could not be absorbed by seed from plant above ground; (2) The underground and above ground seeds could normally germinate, grow, blossom and bear fruits, A. edgeworthii sowed in early May, blossomed in early September and matured in the last ten days of October; (3) The seed leaf of seedling grew underground; (4) The underground seed was produced from subterraneous branch stem which developed from node of seed leaf; (5) A. edgeworthii was shade demanding, high-temperature sensible short-day light plant. The flowering could be greatly advantaged by short-day light treatment (12, 10, 8, 6 h). Cultural practices were studied also in this experiment.</p>
