摘　　要：本文研究了在水仙鳞茎水培期间60Co辐射对植株生长和开花的影响.结果表明20～60Gy的辐射能显著降低水仙花鲜重净增量,抑制根、叶伸长生长,损伤叶片维管束细胞,但对根粗度、叶片宽度及叶片厚度影响甚小,20Gy和40Gy辐射能延长水仙花单花寿命,延迟始花期,提高叶片叶绿素含量,适用于水仙鳞茎的商业化处理.The effect of ^60Co γ-my on growth and flowering of water-planted narcissus bulb was investigated in this paper. The results showed that 20 ～ 60Gy irradiation could obviously reduced the increment of weight of narcissus plant and inhibited the elongation growth of narcissus＇ s roots and leaves, harmed the vascular bundle cells in leaves. But, the roots＇ diameter, leaves＇ breadth and thickness were very little influenced. The life-span of single flower was prolonged, first bloom time was delayed and the chlorophyll content in leaves was increased by 20 and 40Gy treatment, which could fit the commodity treatment of narcissus bulb.
