利用通常的筛选、浮选、风选或肉眼鉴别等方法难以区别美国鹅掌楸翅果种子是否饱满。最近才发明一种利用低剂量 X 射线的鉴别方法。利用 X 射线研究大粒种子是早有的方法,但用以研究小粒的种子饱满度尚属初次尝试。方法是将100到200粒的美国鹅掌楸翅果置于 X 光软片上,使受低剂量软性 X 射线的照 It is difficult to distinguish the Pleurotus ostreatus seeds from the usual methods of screening, flotation, wind selection or naked eye. Recently, an identification method using low-dose X-rays was invented. The use of X-ray to study large seeds is an early method, but it is still an initial attempt to study the seed fullness of small particles. Method is 100 to 200 capsules of American Liriodendron placed X-ray film, so that by low-dose soft X-ray photos
