摘　　要：为了探寻山西省临汾地区‘美乐’葡萄最适冬季修剪方式,试验研究单芽、双芽、三芽以及四芽修剪方式对结果母枝冬芽萌发率、结果枝率、结果系数和花序着生位置的影响。结果表明:随着结果母枝留芽量的增多,基部芽的萌芽率、结果枝率依次降低;随着结果母枝节位升高,结果系数增大,花序着生位置提高;在单、双芽修剪方式下,结果母枝有较高的萌芽率、结果枝率和结果系数;在三芽、四芽修剪方式下,结果母枝基芽萌芽率、结果系数均较低,导致结果部位上移或外移。表明临汾地区‘美乐’葡萄宜采用单、双芽修剪。In order to explore an appropriate winter pruning method for ＇Merlot＇ （Vitis vinifera L. cv. ） in Linfen region, Shanxi province, the germination rate of winter bud on bearing shoot, bearing shoot rate, fructification coefficient and the position of inflorescence for the methods of single bud pruning, double buds pruning, three buds pruning and four buds pruning, four kinds of winter-prun- ing systems were investigated. Experimental results showed that germination rate of the basal bud and bearing shoot rate decreased with the increase of left bud number of bearing shoot~ besides, higher node of bearing shoot resulted in raising fructification coefficient and higher position of inflorescence. Compared with three and four buds pruning of single and double buds, three and four buds pruning had a lower germination rate of bearing shoot, bearing shoot rate and fructification coefficient and resulted in position of bearing moving up and outside. In conclusion, the single bud pruning and double buds pruning methods are appropriate methods for ＇Merlot＇ grapes in Linfen region.
