不同光照处理对黑老虎生长的影响

Effects of Different Light Treatments on the Growth Characteristics of Kadsura occinea

[目的]分析不同光照条件下黑老虎的生长性状和叶片性状差异,为黑老虎作为园林植物的引种机理研究提供有效的参考依据。[方法]以1年生黑老虎幼苗为试材进行盆栽试验,分析100%光照、50%光照、30%光照、10%光照4种处理下生长性状和叶片性状指标的变化情况;采用单因素方差分析、相关性分析等方法进行统计分析。[结果]不同光照处理黑老虎的生长性状与叶片性状差异极显著,但变异性稳定(变异系数均小于10.00%),其中100%光照处理的叶宽变异系数最大,为7.56%。利用相关性分析进一步发现,地径、株高、叶长、叶宽均存在显著相关性,且这些性状与光照也存在显著正相关和负相关。[结论]光照对黑老虎生长的影响较大,30%~50%光照最适宜。

[Objective]To explore the suitable light environment for the growth of Kadsura occinaea,and provide the basis for its artificial cultivation and garden application.[Method]Pot experiments were conducted to study the effects of different light conditions(100%,50%,30%,10%)on the growth and leaf traits of Kadsura occinaea.One way ANOVA and correlation analysis were used for statistical analysis.[Result]The results showed that there was a significant correlation between growth traits and leaf traits and light intensity under different light treatments,but the variability was stable(the coefficient of variation was less than 10.00%),and the coefficient of variation of leaf width under 100%light treatment was the largest,which was 7.56%.The correlation analysis further found that there were significant correlations among ground diameter,plant height,leaf length and leaf width,and there were significant positive and negative correlations between these traits and light conditions.[Conclusion]Light has a great influence on the growth of Kadsura occinea,and the optimum light range for black tiger is 30%-50%.
