摘　　要：选择白网纹草(Fittonia verschaffeltti)作为试验材料,观察其在不同光强处理下的观赏品质,探讨其在不同光照强度处理下形态特性及光合特性发生的一系列适应弱光环境的变化。通过对白网纹草光响应曲线的测定,在栽培时应将光照条件控制在413μmol/m^2·s以下,以免发生日灼现象。白网纹草的光补偿点小于2.1μmol/m^2·s,低于大部分室内照明灯(PAR为18μmol/m^2·s左右)。因此,白网纹草能够适应室内的弱光条件,可以进行合理的室内景观配置。In this paper, Fittonia verschaffeltti ornamental quality under different shading treatments is observed as test material. By exploring their morphological characteristics and photosynthetic characteristics in a series of chan- ges to adapt to low light conditions under different shading treatments, we got the statistic about how the influence of different light on the growth of this species. Measures of the photosynthetic light curves of Fittonia ver- schaffeltti showed that the highest light saturation point reached 413μmol/m2·s. It is suggested that the pho- tosynthetically active radiation （PAR） should be kept below this point. Otherwise, it suffers sunburn and adverse effects in growing. The light compensation point of Fittonia verschaffeltti was lower than 2. lμmol/m2·s ,indi- cating that Fittonia verschaffeltti could adapt to low light conditions （where PAR is about 18μmol/m2·s of indoor environment and were favorable for indoor planting.
