摘要
以桂花幼苗为试验样品,采用二次正交旋转组合实验优化设计方案,研究了光照、温度、湿度和水分4个基础环境因素对桂花幼苗叶片超弱发光值的影响,建立了4因素对超弱发光值的综合影响模型.分析发现:不同因素及其交互作用对超弱发光值影响的显著性也不同;其中4个因素的一次项和光照、湿度、水分因素的二次项,以及光照和水分、温度和湿度的交互项,对超弱发光值的影响极显著(p≤0.01);当光照采用10根灯管(即照度值均值为4 229 Lx)且温度、湿度和水分分别控制在35 ℃、85%和90 mL/d时桂花幼苗的超弱发光值最大.在此基础上进一步分析并获得了对超弱发光值存在影响作用的各单因素及交互作用的影响规律.
Abstract
To obtain the ultraweak luminescence properties of plant affected by multilateral growth, environment factors of osmanthus tree seedings were used as the research material.Quadratic rotation-orthogonal composite experimental design was used to study the effects of illumination,temperature,relative humidity,and moisture on the ultra-weak luminescence of leaves of osmanthus tree seedings.The model of four environmental factors to ultra-weak luminescence of osmanthus tree seedings leaves was established.The ANOVA(analysis of variance) analysis showed that the significant value of influence of different factors and their interaction on ultra-weak luminescence are different.The linear effects of four variables,the quadratic effects of illumination,relative humidity and moisture,and the interaction effects of illumination & moisture and temperature & relative humidity are all significant,with p-value ≤0.01.And when light by 10 stick of lamp tube (intensity of illumination value 4 229 Lx) and mean temperature,humidity and water respectively controlling in 35 ℃ 90 mL/d,85%, the value of ultraweak luminescence was maximum.Based on that,the influence rule of each influential environmental factors and their interactions on the ultra-weak luminescence was also included.
