摘要
2017—2018年以育711桑树品种为试材,对其母枝直径、母枝留芽量、母枝结果量、结果梢芽量、结果梢结果芽百分率和结果梢结果量等6个枝条性状指标,以及单果质量、桑果纵径、桑果宽横径、桑果厚横径、桑果平均横径、果汁含糖量、桑果种子数量、单株产量、果柄长度和果柄直径等10个桑果质量性状指标进行调查,并对桑树各项指标进行相关分析。结果表明:(1)随着桑树母枝直径的减小,桑树母枝结果量和单株产量呈先增加后降低的趋势,均在分组3(25.0mm>d≥22.0mm)达到最大值;(2)结果梢结果量与结果梢结果芽百分率、结果梢结果量与桑葚厚横径、结果梢结果芽百分率与桑葚平均横径、桑葚厚横径与平均横径、果柄直径与桑树桑果纵径、母枝结果量与单株产量显著正相关(P<0.05),而平均横径与桑葚含糖量、母枝芽量与果柄直径、母枝直径与果柄长度、母枝结果量与桑葚宽横径、桑葚宽横径与单株产量显著负相关(P<0.05)。
In 2017-2018, the experiment was conducted with Yu711 mulberry varietiy, six branches trait indices (mother branch diameter, buds number remaining on mother branch, fruits number of mother branch, buds number of fruit branch, fruits number of fruit branch, and rates of fruits number in buds number of fruit branch) and ten quality indices of mulberry fruit (weight per fruit, longitudinal diameter, wide diameter, thick diameter, average width diameter, sugar content, seeds number per fruit, yields per plant, peduncle length, and peduncle diameter) were investigated, and the relationships among the indices were analyzed and discussed. The results showed that with the decrease of the mother branch diameter, the yield per mulberry plant and fruits number of mother branch increased first and then decreased, reaching the maximum value in group 3 (25.0 mm>d≥22.0 mm). There were significant positive relationships (P<0.05) between fruits number of fruit branch and rates of fruits number in buds number of fruit branch, fruits number of fruit branch and fruit thick diameter, rates of fruits number in buds number of fruit branch and fruit average width diameter, fruit thick diameter and fruit average width diameter, peduncle diameter and fruit longitudinal diameter, fruits number of mother branch and yield per plant, while there were significant negative relationships(P<0.05) between fruit average width diameter and fruit sugar content, buds number remaining on mother branch and peduncle diameter, mother branch diameter and peduncle length, fruits number of fruit branch and fruit wide diameter, fruit wide diameter and yield per plant.
