6种常绿藤本植物的生长速度与高度的观测与分析

目的]观测与分析6种常绿藤本植物的生长速度与高度。方法]通过对南京及周边地区的常绿攀缘植物调查和引种栽培,选出6个具开发应用潜力的常绿种络石、洋常春藤、扶芳藤、南五味子、宁油麻藤、薛荔,并对这6种攀缘植物的生长速度和高度方面作了定性的和定量的观测和分析。结果]前10年生长速度由快至慢的顺序为:洋常春藤>扶芳藤>宁油麻藤>薜荔>络石>南五味子,前10年中生长高度由高至低的顺序为:洋常春藤>扶芳藤>薜荔>络石>南五味子>宁油麻藤。结论]藤本植物的攀缘高度与其寄主有关,不同种间攀缘高度差异较大,灰色系统模型并不能描述所有这6种攀缘植物的生长高度。

Observation and Analysis of Growing Speeds and Heights of 6 Evergreen Lianas

Objective]Growing speeds and heights of 6 evergreen lianas were observated and analyzed.Method]By surveying the evergreen liana resources,introductiing and cultivatiing them in Nanjing region,6 potential evergreen species were screened for ornamental application purposes.Qualitative and quantitative measurements were applied to test their growing speeds and heights.Result]The growing speeds in the first ten years from fast to slow was: Hedera helix > Euonymus fortunei > Mucuna paohwashanica > Ficus pumila > Trachelospermum jasminoides > Kadsura longipedunculata.The growing heights in the first ten years from high to low was: Hedera helix >Euonymus fortunei> Ficus pumila > Trachelospermum jasminoides > Kadsura longipedunculata > Mucuna paohwashanica.Conclusion]The climbing heights of lianas were correlated with their hosts.There was a great difference between of climbing height among different species of liana.The gray system can not fit the growing speed and height of all the 6 species of liana.
