Abstract

Morphological ampelography characteristics, technological, phenolic and tannic maturities were studied over four seasons (from 2009 to 2012) of Ahmeur Bouamer autochtonous Algerian variety. During the four harvests, Ahmeur Bouamer's cluster has showed a high quality of morphological parameters (weight, size, number of seeds/ berries per cluster).The weight was proportional to the size of the cluster which was moderately compact, thus avoiding the deformation and the bursting of the berries. As For the maturity index (MI), Ahmeur Bouamer grape recorded values ranging from 31.07 to 54.95 for the four seasons; values which would make it possible to consider that the harvest would be of excellent quality (when 30

对阿赫默布玛尔自产品种的成熟度监测及最佳采收期的确定

研究了2009 - 2012年4个季节阿尔及利亚Ahmeur Bouamer品种的形态特征、工艺成熟度、酚类成熟度和单宁成熟度。在四次收获中，Ahmeur Bouamer的集群显示出高质量的形态参数(重量、大小、每集群的种子/浆果数量)。重量与簇的大小成正比，簇的大小适度紧凑，从而避免了浆果的变形和破裂。在成熟度指数(MI)方面，Ahmeur Bouamer葡萄四季的记录值为31.07 ~ 54.95;当30
