摘要: 以非洲菊为试验材料,研究不同LED反光及照光方式对非洲菊组培苗形态和生理特性的影响,以期为非洲菊工厂化育苗提供技术支撑和理论支持。结果表明:8种反光及照光方式处理(不同光源倾斜角度+不同结构反光膜+纳米导光板:76.39°+M形+纳米导光板、79.89°+M形+纳米导光板、82.59°+凸形+纳米导光板、86.87°+拱形+纳米导光板、69.77°+平面形+纳米导光板、90°+平面形+纳米导光板、180°+纳米导光板、180°)中,处理1—4的株高、叶数、叶幅、整株鲜质量、地上部鲜质量、地下部鲜质量、整株干质量、地上部干质量、地下部干质量、可溶性蛋白含量等指标随照光光源倾斜角度的增加整体呈现先升后降的趋势,而叶长、最长根长、地上部干物率、地下部干物率、总干物率、叶片下表皮气孔大小、气孔面积、根系活力整体呈先降后升或降低趋势。其中,处理4(86.87°+拱形+纳米导光板)的气孔密度、气孔大小、气孔面积、叶绿素含量等光合相关指标整体较优;处理1(76.39°+M形+纳米导光板)的最长根长、根系活力、地下部干物率和总干物率等指标整体较优。综上可知,处理4有利于非洲菊组培苗的光合作用,可促进其地上部茎叶生长;而处理1则利于其根系生长发育和干物质积累。

Abstract: Gerbera jamesonii was used as the experimental material to study the effects of different LED reflecting and lighting methods on the morphological and physiological characteristics of Gerbera jamesonii tissue culture seedlings,in order to provide technical support and theoretical support for industrialized seedling cultivation of Gerbera jamesonii.The results showed that among the eight reflective and lighting methods treatments (Different light source inclination angles+different shape reflective films+nano light guide plates:76.39° +M‑shape+nano light guide plate,79.89° +M‑shape+nano light guide plate,82.59°+convex+nano light guide plate,86.87°+arch+nano light guide plate,69.77°+plane+nano light guide plate,90°+plane+nano light guide plate,180°+nano light guide plate,180°),the plant height,leaf number,leaf width,whole plant fresh weight,aboveground fresh weight,root fresh weight,whole plant dry weight,aboveground dry weight,underground dry weight and soluble protein content of treatment 1—4 showed a trend of increasing first and then decreasing with the increase of the inclination angle of the light source,while leaf length,longest root length,aboveground dry matter rate,underground dry matter rate,total dry matter rate,stomatal size under leaf epidermis,stomatal area and root activity showed a trend of decreasing first and then increasing or decreasing. Among them,the photosynthetic related indexes such as stomatal density,stomatal size,stomatal area and chlorophyll content of treatment 4(86.87°+arch+nano light guide plate) were better than those of other treatments. The longest root length,root activity,underground dry matter rate and total dry matter rate of treatment 1(76.39°+M‑shape+nano light guide plate)were better than those of other reflective treatments. In summary,treatment 4 was conducive to the photosynthesis of tissue culture seedlings of Gerbera jamesonii and could promoted the growth of stems and leaves.Treatment 1 was beneficial to root growth and material accumulation.
