中文摘要 | 青時烏龍及台茶12號茶樹之扞插插穗以慣行法貯放後 青心烏龍莖的乾物重反而略為增加,而葉片則在貯改5日即急速減少;台茶12號堅莖乾物重改變不大,而葉片在貯放7日後,乾物重才有明顯下降。兩品種之扞插成活率在葉片乾物重含量明顯下降後,也明顯降低,顯示茶樹葉片乾物重含量與扞插成活率關係密切。分析插穗中主要營養成分顯示,台茶12號插穗除葉片鎂含量外,其他各成分濃度均略高於青心烏龍,整體而言,植體內80%乙醇可溶性醣在貯改後,其濃度即明顯下降,但澱粉含量則變化不大,枝條中之澱粉含量甚至於會提高。相反的葉片中氮濃度改變不大,而枝條內的濃度則明顯下降,其他大量無機要素濃度改變不大。以植體內養分總含量損失之比例看時,扞插成活率較高的台茶12號損失比例扞插成活率較低的青心烏龍低。其中尤其以葉片中之損失率表現最為明顯。因此,在茶樹插穗貯放過程中,如何保護葉片並降低葉片中乾物重及各種養分之損失,將是維持扞插成活率之要點。 |
英文摘要 | Dry weight, Carbohydrate, nitrogen and mineral elements of 'Chin-Hsin Oolong and "TTESNo. 12" cutting shoots was analyzed after storage. Stem dry weight of "Chsin-Hsin Oolong" increased slightly but no influenced of "TTES No. 12." during storage. Leaf dry weight decreased sharply after storaged 5 days and 7days of "Chin-Hsin Oolong" and "TTES No.12." respectively, cutting survival rate decreased sharply too in the meanwhile. It shown that leaf dry weight comtent was very close related to cutting survival rate. Nutrients content of "TTES No.12." were higher than "Chin-Hsin Oolong" except leaf magnesium content. During storage, 80% etoh soluble sugar content of shoot and nitrogen content of stem decreased significantly, but only slightly change of starch content, moreover would increase in stem. There were no significant chang of macro-mineral nutrients content of leaf. Total amount of all the nutrients in the shoot, except starch content of stem, would significant loss, because of the dry weight loss of cutting. The ratio of nutrients loss in leaf of "TTES No. 12.", which had higher suvival rate, was lower than those of "Chin-Hsin Oolong", It's shown the leaf protection and decrease nutrients loss of cutting shoot were very important practices in tea cutting. |
