摘    要:本文对鸭茅Dactylisglomerata二倍体和四倍体的生物学特性进行了比较研究。结果表明:二者在生长发育时间、速度上明显不同,二倍体鸭茅前期生长缓慢,后期生长迅速;在产草量、再生性、茎叶比方面,四倍体均优于二倍体;对抗逆性它们表现相似。本文还讨论了鸭茅二倍体和四倍体资源开发利用的途径。

关 键 词:鸭茅  二倍体[45CF]  四倍体  生物学特性  比较研究

Abstract:Biological Froperty in diploid and tetrayloid of Dactylis glomeratawas studied, Time and velocity of growth of diploid and tetraploid are quitedifferent, slowly growing during the early period and guickly during the lateperiod.Tetraploid is better than diploid in yroduction of grassl reyroducibilityand stem/ leaf. They are similat in resistanee. The methods of exploiting andutilizing are also discussed.
Keywords:DACTYLIS GLOMERATA  DIPLOID  TETRAPLOID  BIOLOGICAL PROPER  CONTRAST STUDYD
