摘要
为探讨大马士革Ⅲ玫瑰在鄂西地区引种可能性,在湖北兴山县境内选取了不同海拔梯度的试验地进行引种试验,第1年进行生长状况调查;第2年测定功能叶Pn、LMA、WSC、花产量及精油提取率,并记录其物候动态。结果显示:(1)生长状况与引种海拔线性相关;(2)随海拔的升高,展叶期、初花期逐渐后移,花期延长,落叶期提前;(3)引种第2年即开花,单株鲜花的产量在51~517g之间,精油实验室平均提取率0.04%以上;(4)单株鲜花产量与单株总叶面积、WSC均线性相关,与LMA、功能叶Pn线性无关。
In order to investigate the possibility of introduction of Rosa damascene tyigintipetala in the western Hubei, a two-year introduction experiment at different sites along an attitudinal gradient was done in Xingshan, Hubei. Growth status was recorded in the first year. In the second year, photosynthesis rate (Pn), WSC, LMA, flower yield and rose oil extraction rate were measured, the phenology was recorded, too. The results showed: (1) The growth was linearly related to attitude. (2) With attitude increased, the date of leaf unfolding and flowering were later, florescence period got longer and the date of leaf-fell were earlier. (3) It began to flower in the next year of introduction, an individual plant could yield 51-517 g flowers, the average oil extraction rate in laboratory was above 0.04%. (4) Individual yield was linear related to total leaf area and WSC, but had no association with LMA and Pn.
