Abstract: Macro-vascular bundle (MVB) and small-vascular bundle (SVB) of rachis node in two wheat cultivars (T. aestzvum L.)were observed and the relationship between vascular bundle system and ear productivity were analysed. The results showed that the number of MVB and SVB of rachis node decreased from base

Key words: Rachis, Rachilla, Macro, Small-vascular bundle, Grain number, Grain weight
