中文摘要 | 本研究以切接法,成功地完成臺灣烏心石(Michelia compressa var. formosana)與蘭嶼烏心石(Michelia compressa var. lanyuensis)之嫁接。接穗係採自農委會林務局羅東林區管理處21年生長青烏心石採種園之優良母樹,而砧木則為由農委會林業試驗蓮華池分所提供之2年生蘭嶼烏心石生苗。本嫁接試驗自2001年8月及9月之嫁接成活率甚低,為1%;10月以後嫁接成活率漸增至10%;11、12月之嫁接成活率約13%;2002年1月都為23%;2月者為22%,3月者約14%;自4月起至7月都均無成活者。成活之苗木生長情形良好。臺灣烏心石接碳氮比試驗結果顯示,在1,2,3月採集之接,具有較高的碳氮比。生理特性觀察發現,嫁接6個月後,臺灣烏心石與蘭嶼烏心石嫁接苗之光飽和點為1800μmol m□s□,其而淨光合速率為2.7μmol CO□m□s□,低於臺灣烏心石實生苗,蘭嶼烏心石實生苗,及臺灣烏心石與臺灣烏心石嫁接苗之淨光合速率。此一現象顯示,臺灣烏心石與蘭嶼烏心石間具有相當程度的嫁接不親和性。嫁接6個月後,臺灣烏心石與蘭嶼烏心石嫁接苗之光補點為15μmol m□s□,高於臺灣烏心石實生苗及蘭嶼烏心石實生苗之光補償點12.5μmol m□s□,此亦顯示,臺灣烏心石與蘭嶼烏心石間具有嫁接不和性。臺灣烏心石、蘭嶼烏心石、及日本烏心石之DNA逢機擴增多型性試驗結果顯示,臺灣烏心石與蘭嶼烏心石之遺傳相似度較高(0.85),而臺灣烏心石與日本烏心石之遺傳相似度較低(0.53)。此亦可佐證,臺灣烏心石與蘭嶼烏心石間之親緣關係。 |
英文摘要 | We have successfully accomplished the grafting of Formosan michelia (Michelia compressa var. formosana) and Lanyu michelia (Michelia compressa var. lanyuensis) with cutgrafting technique。Scions were collected for grafting experiment form superior seed tree of the 21-year-old Evergeen Formosan Michelia Seed Collection Orchard located at Lo-Tong Forest District, Taiwan Forestry Bureau, COA. The rootstocks of 2-year-old Lanyu michelia seedlings from Lien-Hwa-Chu Experiment Station, Taiwan Forest Resezrch Institute, COA. This study was conducted from August 2001 to July 2002. The survival rates of graftings were about 1% in August and September. It increased to 10% in October, 13% in November and December, 23% in January, 22% in February. However, it decreased to 14% in March. From April to July, there was no survival grafts. The growth of grafts was good. Results from CN ratio analysis of scion showed that there were higher CN ratios in January, February, and March. The physiological characteristics of the grafts were subsequently observed and analyzed. The results revealed that 6 month after grafting, light saturation point of 1800μmol m□s□, and a net photosynthetic rate of 2.7 CO□ μmol m□s□, lower than that of Formosan michelia, Lanyu michelia seedlings, and grafts of Formosan michelia and Formosan michelia, respectively. This phenomenon showed that there was certain extent of graft incompatibility between Formosan michelia and Lanyu michelia. The grafting seedlings had a light compensation point of 15μmol m□s□, higher than that Formosan michelia and Lanyu michelia seedlings. This also showed that there was graft incompatibility between Formosan michelia and Lanyu michelia.Formosan michelia and Lanyu michelia had a genetic similarity of 0.85 from random amplified polymorphic DNA analysis, which was higher that that of Fomosan michelia and Japanese michelia (0.53). This also supported the affinity of Formosan michelia and Lanyu michelia. |
