摘　　要：对经离子注入处理后的3个品种的变异鸡冠花M1代的生长发育和形态变异进行了研究。结果表明:JTM变异的生长发育期比原品种有提早趋势,花冠变紧凑,株高、冠幅、叶形指数和分枝上也有显著变异;YH变异的真叶初始期、出苗期略比原品种早,而抽冠、初花和盛花比原品种晚,花色由鲜红变为深红,株高、冠幅、叶形指数、叶片数、分枝、主花穗长上也有显著变异;ZTH变异的生长发育期与原品种相比略提早,花型变为圆头状,花色有变异为黄色的,株高、分枝和主花穗长上有显著变异;变异均结种子,且有很高的观赏价值。This paper studied the growth and development and morphological variation of M1 population of Celosia cristata treated by ion implantation. The results showed that the stage of growth and development of variant JTM was earlier than control varieties,and corolla became compact. It had significant variation in plant height, crown width, leaf index and branch number. The initial period of true leaf and emergence stage of variation YH was earlier than control varieties, but the squaring period, initial flowering stage, and full-bloom stage was later than control varieties, it＇s flower color changed into dark red, It had significant variation in plant height, crown width, leaf index,leaf number, branch number and the length of main flower cluster. The stage of growth and development of variant ZTH was slightly earlier than control varieties, its flower type became brachycephaly, and flower color was yellow, there was significant variation in plant height, branch number and the length of main flower cluster. All variation of three types Celosia cristata can set seed and had very high popularization value.
