壶瓶枣果实生长动态与气象因子的关系

摘要

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 toresearchgrowthand development dynamics ofjujubefruitanditsrelationshipswithmeteorological factors, taking 10-year HupingJujubeasmaterials, thelongitudinaland transverse diameters offruitsweremeasured by DD-S dendrometer, themeteorologicalfactorsin the orchardwere determinedat the same time,andrelationship between fruitgrowthrhythmandmeteorologicalfactorswasanalyzed. Theresults showed that: Thelongitudinaland transverse diameterswere closelyrelated to dailymean change offruit shapeindexatfruitgrowth period,and their changeswere wavy. The daily changes of thelongitudinaland transverse diameterswere"N" typesatfruit enlargement period, the daily change of thelongitudinaland transverse diameterswere"V" typesatfruitmaturity period. Different meteorologicalfactors hadlarger effects onfruitgrowth.
