Relation analysis on rhizome growth of newly-planted Phyllostachys pubescens

Analysis on rhizome growth factors of newly planted Phyllostachys pubescens showed that there were extremely significant differences in end breakage rate , diameter of rhizome , length of rhizome but significant ones in number of rhizome slice among different ages .There were extremely significant relations between diameter of rhizome and length of rhizome slice or ages but no significant ones between diameter of rhizome and number of rhizome slice , length of rhizome slice or end breakage .There were extremely significant relations between length of rhizome and length of rhizome slice or condition of end breakage but no significant ones between length of rhizome and ages .There were no signidicant relations between diameter and length of rhizome .Regression on diameter of rhizome and every year bud length of new rhizome provided direction for a deep study on rhizome growth regularity of newly-planted phylolostachys pubescens .
