摘要: 本文对鸭茅Dactylis glomerata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。

Abstract: Biological property in diploid and tetraploid of Dactylis glomerata was studied, Time and velocity of growth of diploid and tetraploid are quite different, slowly growing during the early period and quickly during the late period. Tetraploid is better than diploid in production of grass, reproducibility and stem/leaf. They are similar in resistance. The methods of exploiting and utilizing are also discussed.

Key words: DACTYLIS GLOMERATA, DIPLOID, TETRAPLOID, BIOLOGICAL PROPER, CONTRAST STUDYD
