【Abstract】 The present study has approached the causes which affect the seed dormant traits of common wild rice (Oryza rufipogon Griff) and medicinal wild rice (O. officinalis Wall). It shows the seed dormancy relates to genetic traits of wild rice species, morphological characters of plant, pervious traits of lemma and palea and seed physiological traits. The results of this study have provided scientific basis for and suitabl methods of breaking seed dormancy of wild rice and raisingits seed germinant ability.更多还原
