温度和光照对富贵籽果实着色的影响

Effect of Temperature and Illumination on Fruit Coloration of Ardisia Crenate

探讨了温度和光照对富贵籽果实着色的影响，为合理制定富贵籽的栽培技术措施，提高其观赏价值和调节观果时间提供依据。试验结果表明，当果实生长发育到一定程度后，较低的夜温（10～15℃）是诱导富贵籽果实变红的主要因子，而24℃以上的夜温则会抑制果实变红。此外，光照强度与果实着色密切相关，是影响富贵籽果实着色的另一个重要因素。在一定的光照强度（400～10000Lx）范围内，光照越强，果实变红的速度则越快。光周期对富贵籽果实的着色影响不大。

With the aim to provide theoretical basis for formulating cultivation, enhancing ornamental value and adjusting ornamental period of Ardisia crenate ,This study discussed the effect of temperature and illumination on fruit coloration of Ardisia crenate. Experiment results showed,when fruit developed to a certain extent,low night temperature （10 -15 ℃ ） was the major factor which led to fruit color of Ardisia crenata turn red, but fruit coloration was inhibited above 24 ℃. Light intensity was another important one for it was closed related to fruit coloration. Fruit color turned red faster with increases of light intensity among 400 - 10 000 Lx. Photoperiod had little impact on the fruit coloration of Ardisia crenate.
