摘　　要：在吕梁临县引进15个枣树优良品种,对其物侯期、果吊比等生长发育习性进行调查,并测定果实大小、单果重、产量、品质,以及果实的总糖、维生素C,酸度、Ca,Zn等含量。结果表明,木枣萌芽期和展叶期最早,不同枣树品种的萌芽期、展叶期、开花期、坐果期差异较大。各品种的单株产量、果实结果习性、生长发育动态、果实成熟度、裂果情况、果实营养成分等均存在显著差异。15 excellent jujube varieties were introduced to Linxian of Lvliang city.Their growth habit such as the phenological period and the of fruit hanging ratio were investigated.The fruit size,weight per fruit,yield and quality were measured,and the contents of total sugar,vitamin C,acidity,Ca,Zn and so on of the fruit were determined.The results showed that the germination stage and leaf development stage of Muzao were the earliest,and the germination stage,germination stage,leaf development stage,flowering stage and fruit setting stage in different jujube varieties were quite different.There were significant differences in yield per plant,fruit bearing habit,growth and development dynamics,fruit maturity,fruit cracking and fruit nutrient composition among different jujube varieties.
