Abstract: In this paper, light saturation point and light compensation point, p igment content in leaf, theresponse of leaf color to environmental light intensity on 14 kinds of golden-leaf p lantswere measured. The results showed that the chlorophyll content and ratio of Chl. /Car. of golden-leaf plants increased with the descending leaf position and the leaf color ofmost golden2leaf p lantswas affected by environmental light intensity. The golden leave turned green and the content of chlorophyll increased with the decrease of light intensity.According to the sensitivity of leaf color to light intensity, these p lants were divided into three types, namelylight insensitivity, light sensitivity and highly light sensitivity. The light insensitivity type includes Ipom oeabatatas‘Aurea’and Epiprem num au reum. The light sensitivity type includes Celtis ju lianae‘Aurea’, Gleditsia triacanthos‘Sunburst’, Sophora japonica‘Aurea’, Physocarpus opulifolius‘Aurea’, Cornus alba‘Aurea’, L igustrum lucidum ‘Aurea’, Spiraea bum alda‘Goldmound’, B erberis thunbergii‘Aurea’, and thehighly light sensitivity type includes Sam bucus g lauca ‘Aurea ’, Caryopteris ×Clandonensis ‘WorcesterGold’, Forsyth ia koreana‘Suwon Gold’.
Key words: Golden-leaf plant, Pigment content, Leaf position, Light intensity, Light sensitivity
