摘要
以16a生‘北全’葡萄田间结果树为试材,在果实转熟期采用UV-C辐射结合韧皮部环剥的方法,研究了UV-C辐射对葡萄叶片和邻近果穗果实不同器官白藜芦醇(Resveratrol,Res)及其衍生物含量的影响。结果表明:UV-C辐射能够显著提高叶片trans-Res、trans-PD、trans?ε?VIN、trans?α?VIN、trans-RT和trans?δ?VIN含量,而单独的环剥处理则不具备这样的效果;UV-C辐射叶片抑制了邻近枝条韧皮部trans-Res和trans?ε?VIN的积累,环剥能够改变这种结果;而对邻近枝条木质部trans-Res及其衍生物的积累无影响。UV-C辐射叶片能够促进邻近果穗的果穗轴和果皮分别为5种和2种trans-Res及其衍生物的积累,环剥能够阻断这种效应;而对邻近果穗种子trans-Res及其衍生物的积累无影响。
Sixteen-year-old＇Beiquan＇grape （Vitis＇Beiquan＇）fruited trees in the field were used as materials,the effects of UV-C irradiation on trans-resveratrol（trans-Res） and its derivatives＇ contents in the leaves and different organs of neighboring berry clusters of ＇Beiquan grape with the method of UV-C irradiation combined with phloem girdling at veraison were studied. The results showed that UV-C irradiation on leaves （abbreviated as UV-C irradiation） could significantly enhance the contents of trans-Res, trans-piceid （trans-PD）, trans-ε-viniferin （trans-e-VIN）, trans-a-viniferin （ trans-a-VIN） ,trans-resveratrol trimmer（ trans-RT） and trans-δ-viniferin （ trans-δ-VIN） in leaves,while girdling treatment alone could not. UV-C irradiation inhibited the accumulation of trans-Res and trans-ε-VIN in phloem of neighboring branches;additional girdling treatment could change the results. UV-C irradiation had no effect on the accumulation of trans-Res and its derivatives in xylem of neighboring branches. UV-C irradiation could promote the accumulation of 5 and 2 kinds of derivatives of trans-Res in pedicel and berry skins of neighboring fruit clusters;additional girdling could offset this effect. UV-C irradiation had no effect on the accumulation of trans-Res and its derivatives in berry seeds of neighboring fruit clusters.
