Effect of light intensity on the
growth and physiology of Quercus acrodonta seedling
Abstract: In this thesis, the different light the quercus acrodonta seedling growth and physiological impact. Initially proved light, quercus acrodonta seedlings growth and physiological What are the effects. Understanding of the role played by the light in the quercus acrodonta seedling growth. Original plants growing evenly distributed, are numbered, were pided into three groups A, B, C, n = 18 pots, placed under different light conditions, the measurement light response curve, observed quercus acrodonta growing conditions, regular measurement of each crown and leaves of the plant, and observe the color change of the blade while applying some of the controlled-release fertilizer. Final experiment, measured by the light sensor curve, chlorophyll content, specific leaf weight, height, spacing, different light to determine the quercus acrodonta leaf development Final experiment, measured by the light sensor curve, chlorophyll content, specific leaf weight, height, spacing, different light to determine the quercus acrodonta leaf development, collateral, Found that when the light reaches a certain range, quercus acrodonta seedling growth will peak, insufficient light and over-saturated quercus acrodonta will affect the growth of oak seedlings

1.绪论
1.1壳斗科的地理分布
壳斗科植物广泛分布于南、北两半球，主要分布于欧洲（包括地中海周围）、亚洲东半部、北美至中美洲（含南美北部），而北极区、大洋中的岛屿、沙漠、南美洲与撒哈拉沙漠南方的非洲并没有它的踪迹。
壳斗科依不同观点，共6～11属，约900种，主要产于亚洲南部及东南部，中国有栗属（Castanea）、锥属（Castanopsis）、水青冈属（Fagus）、柯属（Lithocarpus）、栎属（Quercus）、青冈属（Cyclobalanopsis）三棱栎属（Trigonobalanus）等7属，约300种。除新疆有引种外，自然分布于南北各省区，主要产于西南及南部。自沿海低丘陵至海拔约3800米高山均有生长，常为山地常绿阔叶或针叶阔叶混交林的主要上层树种，又是山地水源林的重要成分，也是秦岭南坡以南各地的主要用材树种。
