摘　　要：为了提高茭白产量,需要寻找一种快速辨别雄茭的方法。本试验在比较茭白的雄茭与正常茭、灰茭薹管内部结构差异的基础上,通过田间试验验证了薹管内部结构差异与茭白孕茭的关系:正常茭、灰茭的薹管髓腔内有丝状物,而雄茭薹管髓腔内则完全没有丝状物。髓腔内有丝状物的薹管均能孕茭,无丝状物的薹管则不能孕茭。利用薹管髓腔内有无丝状物可以快速区分出雄茭薹管,是一种高效快速辨别雄茭的新方法。In order to increas the yield of Zizania latifolia,it is necessary to find a quick method to distinguish unpregnant plants.Based on comparing the main differences among internal structure of normal swollen culms,swollen culms with Ustilago esculenta and unpregnant plants of Zizania latifolia,this paper verified the relationship between the difference of culm internal structure and formation of Zizania latifolia by field experiment.The results showed that culms with filaments were pregnant,all belonged to normal swollen culms,swollen culms with Ustilago esculenta;and culms without filaments were not pregnant,all belonged to unpregnant plantsof Zizania latifolia.These results indicated that unpregnant plants will be distinguished by finding if there was filaments inside of the medullary cavity of culms.This is a new method for quickly and efficiently distinguishing unpregnant plants of Zizania latifolia.
