生根粉对香蕉组培苗移栽的影响

摘要

The effect of looting powder on transplanting tissue seedling of banana was carried out during 2010～2011 to improve the survival ratio of banana tissue seedling. The results showed that there was very significant effect on transplanting tissue seedling of banana by different looting powder treatment. Compared with treatment 3, treatment 4 and CK,the averages of plant height of treatment 1 and 2 lowed 35.66%, 38.98%, 34.53% respectively; the averages of leaf length shortened 23.89%, 26.56%, 27.35% respectively; the averages of leaf width narrowed 29.14%, 34.38%, 27.10% respectively; and the averages of root length shortened 23.25%, 21.85%, 14.35% respectively. Compared with CK, the difference of plant height, leaf length, leaf width and root length of banana tissue seedling by treatment 3 and treatment 4 were not obvious. The treamentl and 2 had inhibition on the growth of banana tissue seedling, while treatment 3 and 4 could promote the growth and the survival rate of tissue seedling and were time-saving, efficient as well.%为提高组培香蕉苗的成活率,2010～2011年在海南研究了生根粉对香蕉组培苗移栽的影响.结果表明:不同生根粉处理对香蕉组培苗移栽的影响极显著,其中,生根粉1和生根粉2处理的香蕉假植苗与生根粉3、生根粉4和CK的相比,株高平均值分别降低35.66％,38.98％,34.53％,叶长平均值分别短23.89％,26.56％,27.35％,叶宽平均值分别窄29.14％,34.38％,27.10％,根长平均值分别短23.25％,21.85％,14.35％.生根粉3、生根粉4处理的香蕉假植苗株高、叶长、叶宽、根长与CK的相比差异不显著.生根粉1和生根粉2处理对香蕉假植苗的生长有明显的抑制作用；生根粉3与生根粉4处理对香蕉假植苗的生长有促进作用,且具有省时、高效、成活率高等优点.
