壶瓶枣果实生长动态与气象因子的关系

Relationship between fruit growth dynamics of Huping Jujuba and meteorological factors

为了研究枣果实生长发育动态及其与气象因子的关系,以10年生密植壶瓶枣为试材,利用DD-S植物生长动态仪测定了果实的纵横径,对果园内各气象因子进行了同步检测,并分析了果实的生长变化规律及其与气象因子的相关关系。结果表明:枣果实生长期内其纵横径与果形指数日均值的变化密切相关,两者均呈波浪形变化;果实膨大期枣果纵横径日变化曲线呈"N"型,成熟期枣果纵横径日变化曲线呈"V"型;果实生长期枣果受到的不同气象因子的影响都较大。

In order to research growth and development dynamics of jujube fruit and its relationships with meteorological factors, taking 10-year Huping Jujube as materials, the longitudinal and transverse diameters of fruits were measured by DD-S dendrometer, the meteorological factors in the orchard were determined at the same time, and relationship between fruit growth rhythm and meteorological factors was analyzed. The results showed that： The longitudinal and transverse diameters were closely related to daily mean change of fruit shape index at fruit growth period, and their changes were wavy. The daily changes of the longitudinal and transverse diameters were ＂N＂ types at fruit enlargement period, the daily change of the longitudinal and transverse diameters were ＂V＂ types at fruit maturity period. Different meteorological factors had larger effects on fruit growth.
